Optical Rain Gauge

1.Optical Rain Gauge Product Introduction

Optical Rain Gauge uses three-channel narrow-band infrared detectors and pure sinusoidal AC signal sources. It has the advantages of high accuracy, strong resistance to ambient light, maintenance-free, and compatibility with other optical sensors (light, ultraviolet radiation, total radiation). It can be widely used in meteorology, agriculture, municipal administration, transportation and other industries. The sensor adopts a low-power design and can be used in unmanned observation stations in the field.

2. Features of Optical Rain Gauge

The Optical Rain Gauge uses a pure sinusoidal infrared light source, a built-in narrow-band filter, and a rain-sensing surface of 78 square centimeters. It can measure rainfall with high precision and is not affected by high-intensity sunlight. The high-transmittance rain-sensing cover does not affect direct sunlight and is compatible with other built-in optical sensors, such as illumination, total radiation, and ultraviolet sensors.

5. Notes on Optical Rain Gauge

1. The sensor should be within a radius of 1 meter horizontally without any obstruction to avoid the impact of water droplets splashing

2. The sensor should be installed in a place where trees are not blocking the sensor, and the sensor should also be installed in a place where trees are not blocking the sensor.

3. To ensure measurement accuracy, the sensor should be installed horizontally
