Abstract: In view of the difficulty in monitoring the temperature and humidity of plant growth environment, a remote real-time monitoring system for air temperature and humidity and soil humidity is designed. The system uses stm32f103c8t6 microcontroller as the microprocessor, collects air temperature and humidity and soil humidity through temperature and humidity sensor, and then uploads the collected data to the mobile phone through Wi-Fi module, and transmits the data to the cloud server through the mobile phone App, so as to realize the remote real-time monitoring of environmental temperature and humidity. The simulation results show that the monitoring system has strong real-time performance and high intelligence, which meets the requirements of temperature and humidity control of plant growth environment in agricultural production.

Key words: plant growth, temperature and humidity, sensor, App, real-time monitoring
