Zigbee-based Temperature And Humidity Monitoring System Design And Realization

Currently, wireless sensor network is widely used in military, science, medicine, space exploration, people's daily lives, and many other areas. Especially, ZigBee protocol,which has advantages of short range, low-power, low-cost as an emerging wireless sensor network technology is emerged. And it has caused great interest and concern by scientists and engineers at home and abroad.The world's major companies and organizations are generally think that ZigBee technology has potential and value in the future .For the above characteristics, I studied and finished the temperature and humidity system based on the ZigBee protocol. The aim is to reduce agricultural production costs and improve crop output. And China's agriculture moves from manual to automation, information and intelligence. The system detect the growth of crops, the temperature and humidity of the environment,and save the data and analysis the data timely. It can resolve the problems in the growth process of crops and cultivate an excellent crop varieties.This thesis is to design the system based on data transmission methods and algorithms at all levels from ZigBee protocol stack; uses selected hardware chip collecting and transmitting information.Through a reasonable choice of software and hardware, we can making a wireless sensor network, which can control by the control center and complete the various detection tasks.
