ABSTRACT

With the rapid development of embedded computing, sensor, wireless communication technology, wireless sensor network is widely used in environmental monitoring, military defense, industrial and agricultural control fields, has become a hotspot in the development of electronic information technology. CC2530 is a wireless sensor network chip for Zigbee TI solution, with low power consumption, high reliability, simple networking advantages. CC2530 and based on Zigbee protocol, design the temperature and humidity data acquisition system, the software algorithm coordinator and ordinary nodes are given respectively, tested in interference environment, the network has strong robustness and self-organizing ability.

This paper mainly introduces the design of hardware circuit and software flow design of family environment monitoring system based on CC2530 as the core, realizes in the home environment of temperature, humidity. Among them, the analog temperature, humidity, light sensor through the SCM processing output control action corresponding adjusting the corresponding parameters; SCM outputs corresponding protection control: instantaneous over current protection. This design uses Zigbee wireless network protocol, the system parameters of transmission and control, is also available with a PC real-time communication and monitoring.
