RS485 Waterproof Ambient Light Sensor (0-200,000 Lux)

This is a completely waterproof digital ambient light sensor that measures the intensity of light in different environments with a detection range of 0~200Klux. It uses the standard Modbus-RTU 485 communication protocol and a DC5-32V wide voltage power supply. It can be used with the TTL to RS485 expansion board (DFR0259) or the Gravity: Active Isolated RS485 to UART Signal Adapter Module (DFR0845) to read the light value on the Arduino UNO R3, quickly build a test environment, and has a simple wiring method and is easy to use. The ambient light sensor has an IP68 waterproof rating and can be completely immersed in water without damage. It is suitable for various indoor and outdoor harsh environments such as weather stations, vegetable greenhouses, outdoor lighting, flower cultivation, factory workshop lighting, and automotive smart lights.
