The RS485 Photoelectric Solar Radiation Sensor is designed to measure solar radiation in the spectral range of 400-1100nm. It uses the photoelectric principle to convert sunlight into electrical signals. Featuring a highly sensitive photosensitive element and a wide-spectrum absorption range, the sensor delivers accurate solar radiation measurements.

The integrated dust cover, with a transmittance of up to 95%, ensures minimal interference from environmental factors, further enhancing measurement accuracy. Additionally, the sensor operates with a wide voltage range of DC 5-30V and supports Modbus-RTU communication via RS485, making it an ideal choice for integration with Arduino.

Wide Voltage Support

The sensor operates on a DC 5-30V power supply, ensuring compatibility with various systems and making it versatile for different applications.

High Sensitivity and Wide Spectrum Range

Utilizing high-precision photosensitive elements, the sensor ensures accurate measurement across a broad spectrum, from 400 to 1100nm, making it ideal for solar radiation applications in various fields.

Durable and Environmentally Resistant

The sensor is housed in a rugged metal aluminum shell with an IP67 protection level, ensuring durability and reliability even in harsh outdoor environments. The dust cover is specially treated to reduce dust absorption, enhancing long-term stability and performance.
