Abstract:

Based on ZigBee technology, a wireless temperature and humidity acquisition system is designed. The system is deployed in the environment. Nodes communicate spontaneously. The terminal acquisition node can send the temperature and humidity data of the environment to the coordinator for aggregation, and then send it to the host computer through serial port for real-time display. The coordinator can connect the cloud platform with the networking module. After subscribing to related topics, the mini program can also receive the data reported by the coordinator and see the changing tendency of the data. The system can not only be applied to the monitoring of family environment, but also to the industrial and agricultural production.

Key words: ZigBee, temperature and humidity acquisition, wireless transmission, host computer
