1、 Product Introduction
The TH-G1 optical rainfall sensor adopts a three channel narrowband infrared detector ａnd a pure sinusoidal AC signal source. It has the advantages of high accuracy, strong resistance to environmental light, maintenance free, ａnd compatibility with other optical sensors (lighting, ultraviolet radiation, total radiation). It can be widely used in industries such as meteorology, agriculture, municipal engineering, ａnd transportation. The sensor adopts a Low-power electronics, which can be applied to field unattended observation stations.
2、 Product Features
This optical rainfall sensor adopts a pure sine infrared light source, built-in narrowband filter, ａnd a rain sensing surface of 78 square centimeters. It can measure rainfall with high accuracy ａnd is not affected by high intensity sunlight ａnd other light. The high transmittance rain cover does not affect direct sunlight ａnd can be compatible with other built-in optical sensors, such as lighting, total radiation, ultraviolet sensors, etc.
