Specification

Description

A raindrop sensor is basically a board on which nickel is coated in the form of lines. It works on the principle of resistance. The Raindrop Detection Sensor module is an easy-to-use and low-cost drop recognition sensor. The sensor works through a series of exposed parallel traces onboard which produces electrical variations when drops or water volume changes.

Rain Sensor module allows to measure moisture via analog output pins and it provides a digital output when a threshold of moisture exceeds. By using microcontrollers or ADC ICs (Arduino and PIC) it's fairly easy to convert the analog output from the sensor to digital values. This Rain Drops Sensor can be directly read by an Arduino or a comparator circuit if you wish to use it as a rain detection alarm. It can be used to monitor a variety of weather conditions.

Rain Drop Pinout

Wiring

  • VCC: positive power supply (3-5V)
  • GND: power supply is negative
  • DO Digital output pin. It gives the digital output of the internal comparator circuit.
  • AO: Analog output pin. It serves to give analog signals between 0-5 Volts.

Technical Details

  • High-quality double-sided FR-04 material
  • The comparator output signal is clean. And can source up to 15mA
  • Adjustable Sensitivity for D0
  • Working voltage 3.3V-5V
  • Has a fixed bolt hole, convenient installation
  • The output format: digital switching outputs ( 0 and 1 ) and analog voltage output AO
  • Fixed bolt holes for easy installation

Physical Attributes

  • Panel PCB Dimension: Approx.3cm x 1.5cm.
  • Soil Probe Dimension: Approx. 5cm x 4cm.
  • Cable Length: Approx.21cm.
  • Weight (gm): 11

Soldering Job is VERY Sensitive

I had read reviews that the soldering job was not the greatest, but I was very surprised when my order came and already 2/3 of the sensors solders had snapped just in the mail. Fortunately, the third one held on and worked for all of a few minutes. Upon plugging in the sensor, it worked just fine. I then unplugged it and plugged it back in and the THIRD SOLDER SNAPPED! I guess I'll have to return this item but I would really appreciate it if the seller would just send me another. I'm a bit upset but I won't rate the seller bad as their product DOES work, but the solders are just way too sensitive.

Great for many applications !!

I used one in vehicle to Automatically turn on wipers, used one on Garden to automatically turn on Water. Third one still thinking of another application.

So far very pleased....||

I saw a mod where these boards were attached to the Wyze Sensor board to detect moisture. Didn't need the little circuit board provided, just the grid board. Moisture from the finger even will trigger the Wyze Sensor. I'm putting one under the furnace, the water heater, and RO filter to be notified of leaks.

Great addition to watering system

Just what I needed.Added to my Arduino plant watering system

Works well

I have used one of the 3 so far. Good product.

Readily adaptable

Satisfied need for a sensor that could be placed in hard to access locations (inside stud wall) to check for moisture penetration, an application that didn't require the module that connects to the sensor for Arduino use. Simply used the provided wires to connect to an ohmmeter which indicates "infinite" or "open circuit" until a drop bridges the tracings on the sensor. Wrapped the sensor in the toe of a cotton sock to wick up moisture.

3.3V Not compatible

I attempted to use this with an ESP32 and ESP8266 which supply 3.3V and use 3.3V logic without success. I had to use a boost converter to power and a voltage divider to bring the output data into the proper range. Do not trust that your rain sensor will work at 3.3V.
