Abstract
In order to effectively solve the problems of high risk coefficient of artificial temperature measurement in extreme weather, difficult wiring arrangement in industrial production site, and no real-time monitoring data. This paper designs a remote multipoint temperature detection system based on STC89S52 microcontroller, DS18B20 temperature sensor and nRF24L01 radio frequency module as the core System This design ensures that the temperature can be monitored by setting the temperature threshold while detecting and displaying the temperature. When the upper position recognizes that the temperature signal is abnormal, the alarm module can be activated to realize remote and accurate detection and monitoring of real-time temperature in complex environments.
