In order to realize the unmanned detection of temperature,this paper designs an intelligent temperature detection and alarm system based on STM32 microcontroller.The system uses STM32F103 as the main control chip integrating with DHT11 temperature and humidity composite sensors to detect the temperature in the room.When the measured indoor temperature is higher or lower than the preset temperature,the LCD 1602 display screen and LED warning lights will pass the staff related information of temperature ab-normalities.Characterized by low cost and simple operation,the system realizes the intelligent detection of indoor temperature,which has great value in practice.
