Optical Rain Gauge

1.Introduction to Optical Rain Gauge Products

Optical Rain Gauge uses an infrared beam to sense water hitting its outer surface, detecting the size of raindrops and providing the user with information about the intensity of the rainfall.Optical Rain Gauge uses three-channel narrowband infrared detectors and pure sinusoidal AC signal source.It has the advantages of high accuracy, strong ambient light resistance, maintenance-free, and compatible with other optical sensors (light, ultraviolet radiation, total radiation).It can be widely used in meteorological, agricultural, municipal, transportation and other industries.The sensor is designed with a low power consumption and can be used in unattended observation stations in the field.

2.Optical Rain Gauge product features

Optical Rain Gauge uses a pure sinusoidal infrared light source, a built-in narrowband filter, and a rain-sensitive surface of 78 square centimeters.It can measure rainfall with high accuracy and be free from high-intensity sunlight and other lights.The high light transmittance rain cover does not affect direct sunlight and is compatible with other built-in optical sensors, such as light, total radiation, ultraviolet sensors, etc.(Invention Patent, Patent No.ZL 2022 1 1306149.3)

5.Precautions for Optical Rain Gauge

1.The radius of 1 meter around the sensor level is not blocked to avoid the influence of water droplets.

2.The above sensor installation position should avoid obstruction of trees, and the oblique direction should also avoid obstruction of shade.

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