Based on STM32 MCU and HC-05 module, a wireless temperature and humidity detection system is designed. In this system, STM32 is taken as the control core, the digital temperature and humidity sensor AM2303 with low power consumption and fast response is used to collect temperature and humidity signals, and bluetooth technology is used to transmit the detected environmental information, thus completing the remote communication with the upper computer. The problem of complicated wiring of traditional wired monitoring system is solved. Through Bluetooth module, the communication between STM32 single chip microcomputer and host computer can realize the real-time detection of environmental temperature and humidity. When there is danger in the room, the mobile phone or work computer can receive warning signals in time. The experimental results show that the system has the advantages of good real-time, high data transmission reliability and good intelligence, Meanwhile, the cable is saved and the cost is reduced.
