Greenhouse Remote Monitoring Automatic Drip Irrigation System Based on Virtual Instrument

Based on virtual instrument technology and CAN bus technology,the greenhouse remote monitoring automatic drip irrigation system is designed.Its hardware and software are introduced,respectively.The CAN intelligent node with STM32 singlechip as the core collects the signal from soil moisture sensor and uploads it to the LabVIEW monitoring platform,then drives the electromagnetic valve to complete drip irrigation work according to the calculation result of LabVIEW monitoring system and the feedback signal from pressure sensor.Through the related experiments,the results show that the system can realize the automatic monitoring of drip irrigation process.The system has simple hardware,high reliability and can greatly reduce the cost.
