Optical Rain Sensor

Using the principle of optical scanning, real-time scanning of the size and number of raindrops is realized, and then the rainfall output is calculated. Support pulse output and RS232 output, when the pulse output function is used, the infrared rain sensor can completely replace the tipping bucket rain gauge.

Features:

■High sensitivity: Electron optics and a series of microelectronic filtering, amplification, and wave detection technologies are used. This principle has a very prominent sensitivity advantage over conventional mechanical rain gauges.

■Maintenance-free: completely closed structure, no mechanical parts, no wear and tear.

■Easy to install: The infrared optical rain gauge is non-mechanical and non-contact measurement, and there is no horizontal installation requirement.

■Can be measured in motion: there are no mechanical parts inside, and the rainfall can be measured on the go without affecting the accuracy.

■Configurable sensitivity: a programmable light energy monitor is used inside, and the sensitivity to light energy changes can be modified by the user.

■Interference filtering: A lot of research on composite materials has been carried out during the research and development period. The refractive index of the light guide is designed to be almost the same as that of water, which is highly adaptable to the environment and has a learning correction function.

■Tilt correction: The internal tilt sensor participates in the calculation, generates a correction coefficient, and corrects the rainfall.

■Ultra-low power consumption: When there is no rainfall, the device is in a deep sleep state, and it will automatically activate when it rains.

■Data storage: It can store data for more than 10 consecutive years.

High precision: fully compatible with the output signal of the tipping bucket rain gauge, it can directly replace the tipping bucket rain gauge, or connect with the collector of the traditional telemetry rain gauge. It can be configured as a tipping bucket rain gauge with any precision (such as 0.1mm, 0.2mm, or even 0.01mm).

Automatic alarm: There are several alarm values for rainfall and rainfall intensity inside. When the alarm value reaches the rain gauge itself, it will start to flash and output a relay closing signal, which can drive the alarm device installed by the user to alarm (such as alarm lights, radio speakers, Wireless transmitting device with alarm function, etc.), this function can also be used to control automatic doors and windows.

Easy installation: The traditional mechanical rain gauge needs to be installed horizontally. If it is not level, there will be system errors, and in serious cases, it may not be able to operate continuously at all. The infrared optical rain gauge is non-mechanical and non-contact measurement, and there is no horizontal installation requirement, as long as most of the rain receiving surface is upward
