Design of greenhouse environment monitoring system

Nowdays, most greenhouse planting in our country still relies on manual management with low level of automation, which is not convenient for the accurate control of environmental parameters inside the greenhouse, and is not conducive to the release of labor force and the realization of increased production and income. In recent years, with the popularization of Internet of Things technology and the rapid advancement of agricultural modernization, environmental monitoring systems have been widely used in the field of greenhouses, realizing the precision and automatic adjustment of greenhouses parameters, saving a lot of labor and improving the output of crops. This design uses the Internet of Things technology, based on STM32 microcontroller in the UCOSIII operating system to collect the temperature and humidity environmental parameters of the greenhouse, and through the LAN uploaded to the top computer for remote monitoring. And in automatic mode, the single chip microcomputer through pid algorithm automatic control switch, realize the switch solenoid valve, water pump and other electrical functions. In manual mode, you can adjust the environment parameters as required. Realize the control of two modes and adjust the parameters inside the greenhouse accurately. In addition, the upper computer mounted access database for visitors to view environmental parameter data. Through the combination of soft and hard, the waste of labor is reduced and the environmental parameters of greenhouses are precisely controlled.
