After reaching the minimal supply voltage and allowing for the maximal power-up time of 1 ms, the sensor is ready for I2C communication. The quickest way to measure temperature is pseudo-coded on the right-hand side of Figure 1. Using the conversion formulae given in equations ( 1 ) and ( 2 ), the digital signal can be translated into temperature readings.For Code resources, embedded drivers, and CAD files, please refer to the SHT4x files available on GitHub and SnapEDA.2 Sensor Specifications2.1 Sensor PerformanceTable 1. General temperature sensor specifications.Figure 2. STS40 typical and maximal temperature accuracy.1For definition of typ. and max. accuracy, please refer to the document “Sensirion Humidity Sensor Specification Statement”.2The stated repeatability is 3 times the standard deviation (3σ) of multiple consecutive measurement values at constant condit ions and is a measure for the noise on the physical sensor output. Different repeatability commands are listed in Table 6.3Resolution of A/D converter.4Specified range refers to the range for which the temperature sensor specification is guaranteed.5Depends on heat conductivity of sensor substrate and design-in of sensor in application.6Max. value is < 0.04°C/y.3 Electrical SpecificationsValid for all electrical specifications: Typical values correspond to V DD = 3.3 V and T = 25 °C. Min. and max. values are valid in the full temperature range -40 °C … 125 °C and at declared V DD levels.3.1 Electrical CharacteristicsTable 2. Electrical specifications.3.2 TimingsMax. values are measured at -40°C and 1.08 V supply voltage (based on characterization).Table 3. System timing specifications.3.3 Absolute Maximum RatingsStress levels beyond those listed in Table 4 may cause permanent damage or affect the reliability of the device. Kindly note that the reported values are stress ratings only, implying that functional operation of the device under these conditions is not guaranteed. Ratings are only tested separately.Table 4. Absolute maximum ratings.4 Sensor Operation4.1 I2C CommunicationI2C communication is based on NXP’s I2C-bus specification and user manual UM10204, Rev.6, 4 April 2014. Supported I2C modes are standard, fast mode, and fast mode plus. Data is transferred in multiples of 16-bit words and an 8-bit check sum (cyclic redundancy check = CRC). All transfers must begin with a start condition (S) and terminate with a stop condition (P). To finish a read transfer, send not acknowledge (NACK) and stop condition (P). Addressing a specific slave device is done by sending its 7-bit I2C address followed by an eighth bit, denoting the communicationdirection: “zero” indicates transmission to the slave, i.e. “write”, a “one” indicates a “read” request. Schematics of the I2C transfer types are sketched in Figure 3.Figure 3. I2C transfer types: First a write header is sent to the I2C slave, followed by a command, for example “measure T with highest precision”. After the measurement is finished the read request directed to this I2C slave will be acknowledged and transmission of data will be started by the slave.The I2C address is defined by Sensirion and selectable by choosing from a selection of 0x44, 0x45, or 0x46 before ordering. For ordering details, kindly refer to section 8 and 9.4.2 Data Type & LengthThe I2C bus operates with 8-bit data packages. Information from the sensor to the master has a checksum after every second 8-bit data package. Therefore, the temperature data will always be transmitted in the following way (2 * 8-bit data + 8-bit CRC).4.3 Checksum CalculationFor read transfers each 16-bit data is followed by a checksum with the following propertiesTable 5. Data check sum properties.The master may abort a read transfer after the 16-bit data, if it does not require a checksum.4.4 Command OverviewTable 6. Overview of I 2C commands. If the sensor is not ready to process a command, e.g. because it is still measuring, it will response with NACK to the I2C read header.4.5 Conversion of Signal OutputThe digital sensor signal S T corresponds to temperatures, as described in Eqs. (1), and (2).4.6 Serial NumberEach sensor has a unique serial number that is assigned by Sensirion during production. It is stored in the one-time-programmable memory and cannot be manipulated after production. The serial number is accessible via I 2C and is transmitted as two 16-bit words, each followed by an 8-bit CRC.4.7 Reset & AbortA reset of the sensor can be achieved in three ways:• Soft reset: send the reset command described in Table 6.• I 2C general call: all devices on the I 2C bus are reset by sending the command 0x06 to theI 2C address 0x00. • Power down (incl. pulling SCL and SDA low)Any command that triggers an action at the sensor can be aborted via I 2C general call reset or soft reset.5 Physical Specification5.1 Package DescriptionThe STS4x is provided in a dual flat no lead (DFN) package, and comprises the silicon sensor chip made of silicon, which is hosted on a copper lead frame and overmolded by an epoxy-based mold compound.

MODEL 061/063 TEMPERATURE SENSOR OPERATION MANUAL Document No 061-9800061/063 TEMPERATURE SENSORSOPERATION MANUAL1.0 GENERAL INFORMATION1.1 Models 061 and 063 are precision thermistor temperature sensors. For the mostaccurate air temperature measurements, the sensors are always mounted in aradiation shield, which minimizes errors caused by solar and terrestrial radiationheating. Sensors produce resistance change inversely proportional to temperature.Model 061 is designed for air temperature measurement. The Model 061 has a time constant of only 10 seconds.Model 063 is designed for the direct measurement of air, soil, and watertemperature. The 063 sensor is completely sealed in stainless steel housing, filledwith silicone oil. The Model 063 has a time constant of 60 seconds.1.2 Sensor Cable and ConnectionsAll sensors are supplied with signal leads one foot in length. Dependent onparticular applications, longer cable length and cable connectors may be provided as an option.2.0 INSTALLATION2.1 Temperature Sensor InstallationA. AIR TEMPERATUREFor maximum accuracy, it is desirable to mount the temperature sensor in a radiation shield. The radiation shield will minimize effects of solar and terrestrial radiation and will additionally provide adequate air flow over the sensor. Mechanical mountinginformation is given in the radiation shield manual.B. SOIL TEMPERATUREThe Model 063 is used for soil temperature measurements. Installation of the soiltemperature probe requires the digging of a small hole to the required measurement depth in firm, undisturbed soil. The probe is inserted horizontally into this firm soil,and the soil is replaced in the hole and packed firmly.C. WATER TEMPERATUREThe Model 063 Temperature Sensor should be placed in water, free from heatradiation sources.D. These sensors are durable, field proven devices; however,DO NOT DROP OR EXPOSE THE SENSOR TO HEAVY SHOCK2.2 Wiring ConnectionsThe output of the thermistor sensor is a relatively high resistance that variesaccording to temperature. It is important not to introduce any parallel resistancepaths. A parallel resistance path may be established by a dirt/moisture build-upbetween two sensor leads. This may occur in poorly made splices and unprotected connections. It is advisable to always use a protective coating on exposed sensor connections. Use a coating such as silastic rubber (RTV).2.3 Direct Wiring to a Met One Instruments TranslatorWhen the sensor is connected directly to a Met One Instruments Translator Module the sensor is loaded with the appropriate resistor to provide a linear output.2.4 Direct Connection to a Data LoggerWhen the sensor is connected to a data logger the data logger must have aterminating resistor to provide a linear output. Refer to Figure 2-1.3.0 OPERATIONAL CHECK-OUT AND CALIBRATION3.1 Temperature Sensor Check-outCompare sensor readings against a precision mercury thermometer. Use a LoCurrent Digital Ohmmeter and compare readings of temperature vs. resistance. 4.0 MAINTENANCE AND TROUBLESHOOTING4.1 General Maintenance Schedule*6 – 12 Month Intervals:A. Inspect sensor for proper operation per Section 3.1.*Schedule is based on average to adverse environments.4.2 Troubleshooting ProceduresA. Incorrect sensor signal: check sensor input connections: check temperature vs.sensor output signal using Table 3-1. Verify that the sensor has the correctterminating resistor if not used with a Met One Translator.4.3 Temperature Sensor CalibrationThe sensors are tested for calibration conformity at the factory. Field calibration may be verified by testing and sensors against themselves or against a known standard.It is not possible to make alterations to the sensor’s c alibration, as it is fixed.4.4 Ice Bath (0︒C Calibration Test)This calibration test requires that a practical reference point of 0︒C be obtained by the preparation of a mixture of shaved or finely cracked ice and enough water to coverbut not float the ice. To create a precision ice bath (± 0.002︒C), distilled water mustbe used for the bath and to make the ice. This mixture is made and contained in alarge wide-mouth Dewar flask with a capacity of about one quart or more. The Dewar flask is stopped up with a cork or other suitable material, with two holes provided for the insertion of both the temperature and a glass thermometer. Both the probe andthermometer are inserted into the Dewar flask so that the tips of each are at least 4 ½ inches below the surface of the mixture, ½ inch from the sides of the Dewar with aminimum of one inch remaining below.

The temperature reading is provided in a 9–bit, two’s complement reading by issuing a READ TEMPERATURE command. The data is transmitted serially through the 3–wire serial interface, LSB first. The DS1620 can measure temperature over the range of -55°C to +125°C in 0.5°C increments. For Fahrenheit usage, a lookup table or conversion factor must be used.Since data is transmitted over the 3–wire bus LSB first, temperature data can be written to/read from the DS1620 as either a 9–bit word (taking RST low after the 9th(MSB) bit), or as two transfers of 8–bit words, with the most significant 7 bits being ignored or set to 0, as illustrated in Table 3. After the MSB, the DS1620 will output 0s.Note that temperature is represented in the DS1620 in terms of a ½°C LSB, yielding the 9–bit format shown in Figure 2.TEMPERATURE, TH, and TL REGISTER FORMAT Figure 2T = -25°CDS1620Table 3 describes the exact relationship of output data to measured temperature. .TEMPERATURE/DATA RELATIONSHIPS Table 3TEMP DIGITAL OUTPUT(Binary) DIGITAL OUTPUT(Hex) +125˚C 0 11111010 00FA +25˚C 0 00110010 0032h +½˚C 0 00000001 0001h +0˚C 0 00000000 0000h -½˚C 1 11111111 01FFh -25˚C 1 11001110 01CEh -55˚C1 100100100192hHigher resolutions may be obtained by reading the temperature, and truncating the 0.5°C bit (the LSB) from the read value. This value is TEMP_READ. The value left in the counter may then be read by issuing a READ COUNTER command. This value is the count remaining (COUNT_REMAIN) after the gate period has ceased. By loading the value of the slope accumulator into the count register (using the READ SLOPE command), this value may then be read, yielding the number of counts per degree C (COUNT_PER_C) at that temperature. The actual temperature may be then be calculated by the user using the following:TEMPERATURE=TEMP_READ-0.25 + CCOUNT_PER_IN)COUNT_REMA -_C (COUNT_PEROPERATION–THERMOSTAT CONTROLSThree thermally triggered outputs, T HIGH , T LOW , and T COM , are provided to allow the DS1620 to be used as a thermostat, as shown in Figure 3. When the DS1620’s temperature meets or exceeds the value stored in the high temperature trip register, the output T HIGH becomes active (high) and remains active until the DS1620’s measured temperature becomes less than the stored value in the high temperature register, TH. The T HIGH output can be used to indicate that a high temperature tolerance boundary has been met or exceeded, or it can be used as part of a closed loop system to activate a cooling system and deactivate it when the system temperature returns to tolerance.The T LOW output functions similarly to the T HIGH output. When the DS1620’s measured temperature equals or falls below the value stored in the low temperature register, the T LOW output becomes active. T LOW remains active until the DS1620’s temperature becomes greater than the value stored in the low temperature register, TL. The T LOW output can be used to indicate that a low temperature tolerance boundary has been met or exceeded, or as part of a closed loop system it can be used to activate a heating system and deactivate it when the system temperature returns to tolerance.The T COM output goes high when the measured temperature meets or exceeds TH, and will stay high until the temperature equals or falls below TL. In this way, any amount of hysteresis can be obtained.DS1620 THERMOSTAT OUTPUT OPERATION Figure 3OPERATION AND CONTROLThe DS1620 must have temperature settings resident in the TH and TL registers for thermostatic operation. A configuration/status register also determines the method of operation that the DS1620 will use in a particular application and indicates the status of the temperature conversion operation. Theconfiguration register is defined as follows:whereDONE = Conversion Done Bit. 1=conversion complete, 0=conversion in progress. The power-up/POR state is a 1.THF = Temperature High Flag. This bit will be set to 1 when the temperature is greater than or equal to the value of TH. It will remain 1 until reset by writing 0 into this location or by removing power from the device. This feature provides a method of determining if the DS1620 has ever been subjected to temperatures above TH while power has been applied. The power-up/POR state is a 0.TLF = Temperature Low Flag. This bit will be set to 1 when the temperature is less than or equal to the value of TL. It will remain 1 until reset by writing 0 into this location or by removing power from the device. This feature provides a method of determining if the DS1620 has ever been subjected to temperatures below TL while power has been applied. The power-up/POR state is a 0.NVB = Nonvolatile Memory Busy Flag. 1=write to an E2memory cell in progress. 0=nonvolatile memory is not busy. A copy to E2may take up to 10 ms. The power-up/POR state is a 0.CPU = CPU Use Bit. If CPU=0, the CLK/CONV pin acts as a conversion start control, when RST is low. If CPU is 1, the DS1620 will be used with a CPU communicating to it over the 3–wire port, and the operation of the CLK/CONV pin is as a normal clock in concert with DQ and RST. This bit is stored in nonvolatile E2memory, capable of at least 50,000 writes. The DS1620 is shipped with CPU=0.DS1620 1SHOT = One–Shot Mode. If 1SHOT is 1, the DS1620 will perform one temperature conversion upon reception of the Start Convert T protocol. If 1SHOT is 0, the DS1620 will continuously perform temperature conversion. This bit is stored in nonvolatile E2memory, capable of at least 50,000 writes. The DS1620 is shipped with 1SHOT=0.For typical thermostat operation, the DS1620 will operate in continuous mode. However, for applications where only one reading is needed at certain times or to conserve power, the one–shot mode may be used. Note that the thermostat outputs (T HIGH, T LOW, T COM) will remain in the state they were in after the last valid temperature conversion cycle when operating in one–shot mode.OPERATION IN STAND-ALONE MODEIn applications where the DS1620 is used as a simple thermostat, no CPU is required. Since the temperature limits are nonvolatile, the DS1620 can be programmed prior to insertion in the system. In order to facilitate operation without a CPU, the CLK/CONV pin (pin 2) can be used to initiate conversions. Note that the CPU bit must be set to 0 in the configuration register to use this mode of operation. Whether CPU=0 or 1, the 3–wire port is active. Setting CPU=1 disables the stand–alone mode.To use the CLK/CONV pin to initiate conversions, RST must be low and CLK/CONV must be high. If CLK/CONV is driven low and then brought high in less than 10 ms, one temperature conversion will be performed and then the DS1620 will return to an idle state. If CLK/CONV is driven low and remains low, continuous conversions will take place until CLK/CONV is brought high again. With the CPU bit set to 0, the CLK/CONV will override the 1SHOT bit if it is equal to 1. This means that even if the part is set for one–shot mode, driving CLK/CONV low will initiate conversions.3-WIRE COMMUNICATIONSThe 3–wire bus is comprised of three signals. These are the RST (reset) signal, the CLK (clock) signal, and the DQ (data) signal. All data transfers are initiated by driving the RST input high. Driving the RST input low terminates communication. (See Figures 4 and 5.) A clock cycle is a sequence of a falling edge followed by a rising edge. For data inputs, the data must be valid during the rising edge of a clock cycle. Data bits are output on the falling edge of the clock and remain valid through the rising edge.When reading data from the DS1620, the DQ pin goes to a high-impedance state while the clock is high. Taking RST low will terminate any communication and cause the DQ pin to go to a high-impedance state.Data over the 3–wire interface is communicated LSB first. The command set for the 3–wire interface as shown in Table 4 is as follows.Read Temperature [AAh]This command reads the contents of the register which contains the last temperature conversion result. The next nine clock cycles will output the contents of this register.Write TH [01h]This command writes to the TH (HIGH TEMPERATURE) register. After issuing this command the next nine clock cycles clock in the 9–bit temperature limit which will set the threshold for operation of the T HIGH output.Write TL [02h]This command writes to the TL (LOW TEMPERATURE) register. After issuing this command the next nine clock cycles clock in the 9–bit temperature limit which will set the threshold for operation of the T LOW output.Read TH [A1h]This command reads the value of the TH (HIGH TEMPERATURE) register. After issuing this command the next nine clock cycles clock out the 9–bit temperature limit which sets the threshold for operation of the T HIGH output.Read TL [A2h]This command reads the value of the TL (LOW TEMPERATURE) register. After issuing this command the next nine clock cycles clock out the 9–bit temperature limit which sets the threshold for operation of the T LOW output.Read Counter [A0h]This command reads the value of the counter byte. The next nine clock cycles will output the contents of this register.Read Slope [A9h]This command reads the value of the slope counter byte from the DS1620. The next nine clock cycles will output the contents of this register.Start Convert T [EEh]This command begins a temperature conversion. No further data is required. In one–shot mode the temperature conversion will be performed and then the DS1620 will remain idle. In continuous mode this command will initiate continuous conversions.Stop Convert T [22h]This command stops temperature conversion. No further data is required. This command may be used to halt a DS1620 in continuous conversion mode. After issuing this command the current temperature measurement will be completed and then the DS1620 will remain idle until a Start Convert T is issued to resume continuous operation.Write Config [0Ch]This command writes to the configuration register. After issuing this command the next eight clock cycles clock in the value of the configuration register.Read Config [ACh]This command reads the value in the configuration register. After issuing this command the next eight clock cycles output the value of the configuration register.DS1620 COMMAND SET Table 4INSTRUCTION DESCRIPTION PROTOCOL 3-WIRE BUSDATA AFTER ISSUING PROTOCOL NOTESRead Temperature Reads last converted temperaturevalue from temperature register.
