Quick Overview
The DIYables rain sensor module effectively detects rainfall, allowing you to monitor weather conditions and automate actions in response to rain. It uses a detection board that senses water droplets and changes its output accordingly.
The module provides both analog voltage output for measuring rain intensity and digital switch output for simple rain/no-rain detection. Sensitivity is adjustable via a built-in potentiometer. It works with Arduino, ESP32, ESP8266, Raspberry Pi, and other 3.3V-5V microcontrollers for weather stations, irrigation systems, and outdoor automation.
Key Features
- Rain Detection — Effectively detects rainfall for weather monitoring and automation
- Adjustable Sensitivity — Built-in potentiometer for fine-tuning detection threshold
- Dual Output — Both analog voltage and digital switch outputs
- Wide Voltage Range — Compatible with 3.3V to 5V power supply
- Weather Automation — Ideal for automatic window closers, irrigation control, and outdoor alerts
- Presoldered and Not Soldered Options — Provided in presoldered and not soldered versions for selection
- Tutorial Support — Comprehensive tutorials and MicroPython support for Arduino, ESP32, ESP8266, Raspberry Pi, and Pico
- ...NOTE
- If you are using the ESP32, you need to configure the ADC with 11 dB attenuation to set the voltage reference range to handle up to 3.3V.
