ES-S229 Sunshine Duration Sensors

ES-S229 sunshine duration sensor is used to continuously measure the hours of sunshine. When the value of the radiation voltage on the instrument is greater than a preset threshold (200MV), the time is accumulated, and the zero is cleared daily.

ES-S229 sunshine duration sensor is used to continuously measure the hours of sunshine. When the value of the radiation voltage on the instrument is greater than a preset threshold (200MV), the time is accumulated, and the zero is cleared daily. It is automatically recorded by the collector as the sunshine. Hours. The instrument itself has no moving parts and low power consumption, and can be used for long-term observation in the field. The core device of the sunshine hours sensor is a high-precision photosensitive element, which has good stability and high precision. At the same time, an anti-ultraviolet and anti-aging light cap made of precision optics is installed outside the sensing element, which effectively prevents environmental factors from affecting its performance.
