DFRobot SEN0640 RS485 Photoelectric Solar Radiation Sensor
DFRobot SEN0640 RS485 Photoelectric Solar Radiation Sensor is a high‑precision instrument designed to measure solar radiation in the 400nm to 1100 nm spectral range using a sensitive photoelectric element that converts sunlight into electrical signals for accurate, stable output. An integrated dust cover, featuring up to 95% light transmittance, minimizes environmental interference and enhances long‑term measurement reliability, while the rugged IP67 aluminum housing ensures durability in harsh outdoor conditions. Operating on a wide 5VDC to 30VDC power supply and supporting Modbus‑RTU RS485 communication, the sensor integrates easily with Arduino and industrial systems, enabling rapid deployment for data collection and monitoring applications. The DFRobot sensor offers a measurement range of 0W/m2 to 1800W/m2, ±5% accuracy, 1W/m2 resolution, and a response time of ≤10s, making the device well‑suited for dynamic, real‑time analysis.
