Turkey-based Seven Sensor has developed a new thermopile pyranometer for the monitoring of solar radiation in photovoltaic plant and meteorological stations. These specialized instruments are designed to measure global horizontal irradiance, which is the power of solar radiation received on a given surface area.
This new tool has an irradiance measurement range of 0 W/m² to 4,000 W/m², with a resolution of 0.1 W/m². The Class A pyranometer is fully compliant with IEC 61724-1:2021 and ISO 9060:2018 standards, ensuring

In addition to irradiance, the sensor can measure internal and housing temperature as well as internal humidity. The internal humidity is measured within a range of 0% to 100%, with a resolution of 1% and an accuracy of ±1%. Both internal and housing temperatures are in the range of -40° C to 85° C, at a resolution of 0.1° C. Measured irradiance, humidity and temperature data are transmitted to data loggers via serial RS485 interface with Modbus RTU protocol.
A built-in LED indicator provides real-time feedback on the device’s operational status and ensures users can quickly verify that it is functioning properly, reducing downtime and improving system reliability.
