Product Description:
The Raindrops Detection sensor module is used for rain detection. It is also for measuring rainfall intensity. The rain sensor can be used for all kinds of weather monitoring and translated into output signals and AO.
Raindrops Detection Sensor Module Rain Weather Module for Arduino, etc. The rain sensor can be used to monitor a variety of weather conditions and turned into several fixed output signal and Analog output.
It includes a printed circuit board (control board) that “collects” the raindrops. As raindrops are collected on the circuit board, they create paths of parallel resistance that are measured via the op-amp. The lower the resistance (or the more water), the lower the voltage output. Conversely, the less water, the greater the output voltage on the analogue pin. A completely dry board, for example, will cause the module to output 5V.
The robot kit for Arduino, raindrop, rain, humidity sensor plant leaves can be used to monitor various weather conditions and has relay outputs that directly control the motor as well as other startup and shutdown.
This Raindrops Detection Sensor Module with 12V Relay Module sensor is made of high-quality double-sided fr-04 item material with a large area of 5.0* 4.0cm and a surface coated with nickel. It has the characteristics of oxidation resistance, electrical conductivity, superior performance and long service life. It is directly equipped with power relay module for load control. you can Adjust the sensitivity distribution position and control the opening of the relay under different humidity control.

Raindrops Detection Sensor Module with 12V Relay Overview
The Raindrops Detection Sensor Module with 12V Relay is a compact weather sensor designed to detect the presence and intensity of rainfall. It converts water droplets landing on its 55 x 40 mm PCB into both analog and digital signals, and drives a 12 VDC relay for direct control of external circuits.
Key Features of Raindrops Detection Sensor Module with 12V Relay
- 12 VDC Relay Output: Switch up to 250 VAC/10 A or 30 VDC/10 A directly when rain is detected.
- LM393 Comparator: On-board wide-voltage comparator provides reliable threshold detection.
- Dual Outputs: Both analog (AO) for rainfall intensity measurement and digital (DO) for on/off signaling.
- LED Indicator: Built-in status LED lights up when the relay is activated.
- TTL & Arduino Compatible: Direct interface with Arduino or other microcontrollers at logic level.
- Fast Shipping: Genuine product shipped quickly from Zbotic’s warehouse.
Applications and Use Cases
- Automatic garden irrigation systems that pause watering during rain.
- DIY weather stations monitoring rainfall intensity in real time.
- Outdoor lighting or window covers that retract when rain is detected.
- Greenhouse ventilation controls to protect plants from over-watering.
- Rain alarms for boats, balconies or patios to prevent equipment damage.
- Integration with home automation platforms for smart environment reactions.
How to Use Raindrops Detection Sensor Module with 12V Relay
Connect the module’s VCC to a 12 VDC supply and GND to common ground, then wire the AO and DO pins to your microcontroller’s analog and digital inputs. Adjust the onboard potentiometer to set the rain-detection threshold. Use the COM, NO and NC relay terminals to switch external loads such as pumps or alarms when rain is detected.

Frequently Asked Questions
What supply voltage is required for this sensor module?
The relay and comparator circuit require a 12 VDC power supply. Do not exceed 12 V to avoid damaging the onboard components.
How do I adjust the rain sensitivity threshold?
Turn the blue trim potentiometer on the control board clockwise or counterclockwise to raise or lower the analog threshold at which the digital output triggers the relay.
Can I read the analog output on a 5 V microcontroller?
Yes. The AO pin provides a voltage proportional to rainfall intensity up to the module’s supply voltage. When using a 5 V ADC, power the module at 5 V and the AO output will scale accordingly, though relay switching requires 12 V.
