The temperature and humidity in the greenhouse can be adjusted with the help of microcontroller system.The system uses STC89C52RC microcontroller,uses DHT11 temperature and humidity sensor to obtain temperature and humidity informa-tion,and the results are displayed on LCD1602 LCD.When the temperature and humidity do not meet the requirements,they can be automatically adjusted.The system development is simulated in Proteus,and implemented and tested in specific hard-ware.The hardware circuit of the system is simple,the cost is low,and it can meet the requirements of greenhouse.
