Design of temperature and humidity acquisition system in greenhouse

based on single Chip Microcomputer

Design overview:

temperature and humidity are one of the common and basic parameters in agricultural production. Modern science and technology play an important role in improving agricultural productivity to determine temperature and humidity, real-time display, storage and monitoring. Domestic production, product quality and energy saving. In this paper, a new modern temperature and humidity acquisition system for hardware and software greenhouse is designed by SCM, transducer, computer technique .

The system takes single chip microcomputer as the first basic point, and uses multiple temperature sensors and humidity sensors as acquisition components. The single chip microcomputer is connected to the digital sensor to collect and store the measurement data of the sensor. The MCU (Microcontrol Unit) sends the collected data to the computer via RS-232. Computer stores, records the data sent by MCU for employees for browsing, recording and related processing. In another place, MCU needs to realize the expansion of monitoring system, the real-time display of data and the function of data storage.

This paper mainly completes the following aspects: first of all, the general direction of the system is summarized, the sensors consistent with the system are selected, and the hardware and software are designed according to the selected sensors. Secondly, data collection: including temperature and humidity digital control, monitoring principles, monitoring planning and monitoring system software development. The system can collect and monitor the temperature and humidity in greenhouse environment in a comprehensive and timely manner, and can also save and record the previous data, which is convenient for people to view and compare the data in time. In addition, a display module is designed. By using graphics to display parameters more intuitively, the intelligence is realized. The idea of remote monitoring temperature and humidity.
