Abstract

Based on the science and technology plan project of Shandong province, this paper designs an automatic control system based on the temperature, humidity and light intensity of the embedded agricultural greenhouse. The system uses DHT11 temperature and humidity sensor and BH1750 light intensity sensor to collect environmental information and transmit the collected data to the STM32F103ZET6 microcontroller for processing and sending out control signals. The system is simple in operation, low in cost and high in precision.
