In this paper, we tried the design of an economical system to control various LED lightings using Arduino MKR WiFi 1010 and RS-485 based Modbus protocol. The key features of the lighting system based on a timer were overall lighting ON/OFF, user-adjustable dimming, and sensor-integrated automatic dimming. The master device read data once from sensors, which were installed on each floor of the module composed of multi-layered beds, and uploaded this data to a server via MQTT. It compared the data to the pre-configured target sensor values by user and the master processed the data into dimming control values and wrote the values to the corresponding holding register in slave devices. The lighting system used in the test consisted of LED lightings(1200mm bar-type Quantum-dot lighting) with SMPS supporting 1-10V dimming, a master board, sensor boards, and LED control boards. All components were self-developed. The system was installed for pilot testing in a 2-layer system in a closed green house. Occasional issues were observed, which can be resolved, such as relay control failures and sporadic communication errors. This system configuration was expected to provide precise automatic light control, thereby improving crop productivity and quality.
