KQS-RS1
The KQS-RS1 Droplet-Sensing Rain Sensor adopts an innovative droplet-sensing design concept. Inside, a special structure precisely controls raindrop size, and optical sensing is used to count raindrops, thereby measuring rainfall intensity. Unlike traditional tipping-bucket, pressure-type, or optical rain sensors, it combines the advantages of all three principles while overcoming their disadvantages, achieving both compact size and accurate measurement.
Widely used in smart agriculture, meteorological environmental protection, smart irrigation, maritime navigation, automatic weather stations, and geological disaster monitoring.

(1) If used with our company's weather station, connect the sensor cable directly to the corresponding interface on the weather station.
(2) For other output signal types, the wiring sequence and functions are as follows:
| Wire Color | Voltage | Current | Pulse | RS485 | RS232 |
|---|---|---|---|---|---|
| Red | Power + | Power + | Power + | ||
| Black | Signal | Signal | Signal | A+ | RX (COM Pin 2) |
| Yellow | B- | TX (COM Pin 3) | |||
| Green | Power - | Power - | Power - | ||
| Brown | Shield GND | Shield GND | Shield GND | ||
| White | Signal | Signal | Signal |
F = Rainfall intensity
I = Sensor output current (mA)
V = Sensor output voltage (V)
A = Range width (upper limit minus lower limit)
B = Range minimum value (lower limit)
Example: Range 0-4mm → A=4, B=0
Mounting hole diameter: 3.2mm
Bolt circle diameter: 83mm
Connector diameter: 15mm (reserve 25mm for wiring – wire first, then mount sensor)
