Optical Rain Sensor, Pulse/RS485

An optical rain sensor with pulse/RS485 output is for sale, suitable for a variety of climate monitoring scenarios. The power supply voltage is between 10~30V DC and the power consumption is only 0.24W, which is energy-saving and efficient. Its rainfall resolution is 0.1mm, and the maximum instantaneous rainfall is up to 24mm/min with an accuracy of ±5%. The rain sensor has excellent environmental adaptability, can be used in the temperature range of -40°C to 60°C, humidity tolerance up to 99% RH (non-condensing), and has excellent long-term stability, suitable for long-term monitoring and intelligent weather equipment.

Specification

Features

1. Small and Lightweight: The optical rainfall sensor is small and lightweight, it can be easily lifted by one hand, easy to carry and does not take up much space.
2. Optical Sensing Measurement Principle: The optical sensing principle is used to measure rainfall, with infrared light as the measurement medium, and the measurement accuracy is high.
3. High-precision Optical Probes: The sensor has four built-in high-precision optical probes, making the measurement results accurate and sensitive.
4. Automatic Interference Filtering: Reliable filtering algorithms are used to avoid the interference of external light and fog on the detection of rainfall sensors.

Installation and Commissioning

Note:

1. Firstly, you need to install the rain sensor in an open place, there should not be any obstruction around and above to cover it.
2. Mount the optical rain sensor to the bracket in the accessory first, and fix the device and bracket with 4 M4*35 304 stainless steel screws and nuts. Then install the bracket to the position to be installed (to be installed in the position to be opened in 5 holes), bracket to be installed horizontally, and finally through three M4 * 10 304 stainless steel screws and nuts to fix the bracket and rainll sensor.
3. If the bracket is not used, the user can install according to the position and size of the copper studs according to their own installation method.

Applications

Tips: Optical rain sensor daily maintenance

ATO optical rain sensor can be outdoors for a long time, the use of the environment is quite harsh, so the surface of the rain sensor should be kept clean, often wiped with a soft cloth, the instrument for long-term work is generally cleaned once a month, three months must be cleaned once. Do not use the rainfall sensor in any place where it may cause serious consequences due to incorrect indication of the sensor. The system designer or system integrator should ensure fault tolerance to avoid the failure of a single component (including the rain sensor) leading to catastrophic consequences.
