Granary Temperature and Humidity Measurement System based on Zigbee Network

Aiming at the problem of intelligent monitoring in grain storage, a design plan of temperature and humidity is proposed based on ZigBee wireless network. The system integrates the SCM technology, computer technology, intelligent sensor technology and wireless communication technology, using STC89C52 microcontroller as the control chip, SHT11 as an integrated temperature and humidity sensor, and using ZigBee as the data transmission of wireless network, PC machine as the position machine to achieve human-computer interaction. Practice has proved, the wireless sensor network system overcomes the limitations of wired sensor networks, and the whole system is easy to operate, strong expansibility, realizes the intelligent management of the granary and has higher application value.
