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 5V_DC to 30V_DC 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.
