The Solar Radiation Sensor uses photoelectric principle to convert sunlight into electrical signals, measuring 400-1100nm spectral radiation. It has high-precision elements, a 95% transmittance dust cover, Modbus-RTU 485 protocol, 5-30V wide voltage, IP67 aluminum shell. Works with Arduino via adapters, ideal for crop monitoring, photovoltaics, meteorology.

1. Example Code for Arduino-Read Solar Radiation Value
This project demonstrates how to use the RS485 Photoelectric Solar Radiation Sensor with Arduino UNO R3 to read and display real-time solar radiation values. Users will learn RS485 communication setup, Modbus-RTU protocol implementation, and data parsing for environmental sensing applications.
Reference
This article offers an in-depth exploration of the Modbus-RTU communication protocol, detailing communication parameters, data frame formats, register addresses, and providing practical examples for managing solar radiation values, modifying device addresses, and baud rates.
FAQ
1. The sensor is a precision device, please do not remove the protective transparent cover at will
2. If the reading value is 0, check whether there is a light source and whether the product protective cover is removed
3. The 485 bus is disconnected, or the A and B lines are connected in reverse
4. Check whether the power supply meets the marking
5. The dust cover must be kept clean and wiped with a soft cloth regularly
6. There must be no water in the dust cover. If there is heavy rain, snow, ice and other long-term weather, it is recommended to cover it
