A silicon sensor with RS485 communication for continuous monitoring of solar radiation.
Key features
A silicon photoelectric element for fast response and low power consumption.
Applications
Suited to agriculture, solar energy and monitoring of atmospheric conditions.
What this product isThe sensor measures global solar radiation in the 300 to 1100 nm spectral range. The silicon photoelectric element provides fast response, low power consumption and stable operation in agrometeorological conditions.
The technical values apply to the selected RS485 version for integration with the AGRO VEDA station.
Specifications| Measurement | |
|---|---|
| Spectral range | 300 to 1100 nm |
| Measuring range | 0 to 1500 W/m² |
