Design of Agricultural Greenhouse Environment Measurement and Control System Based on LoRa Wireless Sensor Network
Greenhouses are an important environment for planting off-season crops,and the environmental parameters of green-houses directly determine the production quality and quantity of crops.However,existing measurement and control systems have cer-tain errors in environmental temperature and humidity testing due to factors such as weather conditions.In order to meet the growth needs of crops and improve accuracy,an optimized agricultural greenhouse environment measurement and control system based on Lo-Ra wireless sensor network is proposed.By modifying the sensor equipment and adjusting the internal structure of data processors and controllers,the system database and LoRa wireless sensor network are established,and the real-time environmental data of the green-house are collected to transmit the system terminals.The control variables are calculated and adjusted to achieve the measurement and control function of the agricultural greenhouse environment.Experimental results show that compared with traditional measurement and control systems,the optimized system significantly reduces the errors of environmental temperature and humidity by 3.65 ℃ and 3.75%,respectively.
