Automatic Temperature and Humidity Detection and Alarm System for Greenhouse

Abstract

With the continuous development of agricultural production technology, greenhouses have been widely used in the production of agricultural products. Temperature and humidity are important parameters in greenhouses. The real-time detection and regulation of temperature and humidity in greenhouses plays an important role in crop cultivation. This paper designs an automatic detection and alarm system for greenhouse temperature and humidity based on STM32. The system uses STM32F103C8T6 single chip core module as the microcontroller, uses temperature and humidity sensor DHT11 to obtain temperature value and humidity value, and uses LCD1602 liquid crystal module to display monitoring data and Bluetooth module. Together form a temperature and humidity detection system. Through system function testing, the system can operate stably according to the expected requirements and meet the expected requirements. Finally, an intelligent temperature and humidity monitoring and alarming system that can monitor the temperature and humidity in the greenhouse in real time is realized. The system has the advantages of good stability, high precision and convenient operation, which is of great significance for improving the monitoring and management of temperature and humidity and agricultural production.
