Key features
- Analog output rises when water drops are detected on the sensing area.
- Output voltage varies linearly with water amount — from drizzle to heavy rain.
- New revision updates module size and pad shape; functionality unchanged. Ideal for weather stations and smart umbrellas.
Frequently asked about this product
How do I connect the Water Drop / Rain Sensor to my controller board?
The Water Drop / Rain Sensor uses the standard 3-pin GVS (Ground-VCC-Signal) interface with an XH2.54 connector, so it plugs straight into Arduino UNO, ESP32, micro:bit and our sensor shields with a regular sensor cable — no soldering required. It works with Arduino IDE, Mixly, Mind+, Scratch and mBlock.
What voltage does the Water Drop / Rain Sensor run on?
The Water Drop / Rain Sensor runs from a standard 3.3-5 V DC supply (USB or the controller’s 5 V rail). It draws only a few milliamps in normal operation, so it is safe to power from the controller board itself for classroom builds.
What projects is the Water Drop / Rain Sensor good for?
The Water Drop / Rain Sensor is built for STEM and robotics education: classroom demonstrations, science-fair projects, robotics club builds and competition robots. It pairs with the rest of our module range — same connectors, same voltage, same toolchain — so students move from first circuit to competition robot without changing platforms.
What certification do the robotics and electronics products carry?
Controller boards, sensors and modules ship with CE marking and RoHS-compliant components, and the range is designed for classroom use under teacher supervision. Product-specific test reports and declarations of conformity are available for distributors on request.
What is the minimum order quantity, and can I get a sample first?
These are standard catalogue lines with stable production, so minimums are low and lead times are short. Samples ship within about a week and are normally credited against a first order. Mixed-SKU cartons are accepted for evaluation orders.
