Design and Implementation of an Intelligent Wireless Multi Point Temperature Monitoring System

In order to improve the efficiency of temperature measurement and realize long-distance multi-point accurate measurement, a multi-point intelligent wireless temperature monitoring system based on nRF4L01 wireless transceiver chip is designed. The system is divided into a host computer and several slaves. The slaves first collect temperature signals using DS18B20 temperature sensor, and then compare the collected temperature values with the set temperature, so as to work on the temperature control equipment. At the same time, the slave computer controls the wireless transmission module to upload temperature data to the host microcontroller for LCD display. Experiments show that multi-point temperature real-time acquisition and control can be realized at 500 m distance, and the error is in the range, and the work is stable, which can meet the functional design requirements.
