Frequently Asked Questions

What is the communication protocol and wiring for this solar radiation sensor?

The sensor uses an RS485 interface and communicates via the Modbus RTU protocol. It is typically wired using a 4-wire connection (A, B, power+, and ground) as per the included cable. Ensure your host device (PLC, data logger, or gateway) is configured for Modbus RTU slave addressing and uses matching baud rate, parity, and stop bit settings for successful data polling.

What is the required power supply, and can it be solar-powered?

The sensor operates from a wide DC voltage range of 7 to 30 volts, consuming only 0.06W. This low power requirement and wide input range make it highly suitable for direct connection to 12V or 24V industrial power supplies or for integration into off-grid, solar-powered monitoring stations with appropriate voltage regulation.

How do I install and calibrate this sensor for accurate measurements?

For accurate hemispherical measurement, mount the sensor horizontally using the provided screw set and utilize the integrated bubble level for alignment. The sensor is pre-calibrated and features high annual stability (≤±2%). No user calibration is typically required, but periodic cleaning of the high-transparency dust cover is recommended to maintain optimal accuracy.

What environmental conditions can this sensor withstand?

Built with a durable aluminum housing, the sensor is designed for continuous outdoor operation. It is rated for an operating temperature range of -25°C to +60°C and can withstand 0-100% relative humidity. Its design includes environmental protection features suitable for harsh meteorological and industrial field conditions.
