Optical Rain Gauge

1.Optical Rain Gauge Product Introduction

Optical Rain Gauge determines the presence of raindrops by transmitting beams and receiving scattered light, and calculates rainfall based on the number and size of raindrops.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
