Bluetooth Mesh Network-based Intelligent Light Replenishment System for Agricultural Greenhouses

Abstract Given the actual situation of greenhouse production nowadays, this paper proposes a kind of intelligent light replenishment system for greenhouses based on a Bluetooth Mesh network. The system uses the ESP32-C3FH4 microcontroller from Espressif as Bluetooth Mesh nodes to form a Bluetooth Mesh monitoring network. This paper designs an intelligent IoT device control system based on Bluetooth Mesh network technology and cloud platform services. Through the flooded network composed of Bluetooth Mesh, the natural light intensity data monitored by each service node is sent to the cloud platform periodically through the gateway, the monitored data is accessed by the cloud platform for management, and the artificial light source module is triggered according to the deposited data to realize automatic control, realizing the modernized digital management function of agricultural greenhouses.
