What it is
The Rain and Water Level Detection Sensor Module for Arduino, Raspberry Pi & ESP32 is a liquid presence and surface moisture sensor for detecting rainfall, water contact, and rising water levels in DIY electronics and automation projects. It is useful for leak alarms, tank monitoring, flood warning, smart irrigation, greenhouse control, weather stations, robotics, and pump or shutoff triggers. This is a simple water detection module rather than an I2C, SPI, or UART sensor board, so check the pinout and listing photos for board-specific wiring details.
Pins
Refer to the silkscreen labels on the board/module and the listing photos for exact pin names. This listing does not provide a full pinout or datasheet, so verify the board markings before connecting it to Arduino, Raspberry Pi, or ESP32.

Frequently Asked Questions
How do I use this rain and water level detection sensor module with Arduino or ESP32?
Wire the module according to the board silkscreen and listing photos, then read its output in your Arduino or ESP32 code. When water reaches the sensing area, you can use that signal to trigger an alert, pump, relay, or shutoff action.
Can this water detection sensor module work with Raspberry Pi?
Yes, it is described as suitable for Raspberry Pi projects as well as Arduino and ESP32. Confirm the module's output labeling and wiring from the board markings before connecting it to your Pi setup.
Does this rain sensor module use I2C, SPI, or UART?
No I2C, SPI, or UART interface is described in the listing. It is presented as a simple water presence and moisture detection module, so check the pinout on the board for exact connection details.
What projects is this rain and water level sensor good for?
Good uses include rain alarms, leak detection, tank monitoring, flood warning, smart irrigation, greenhouse control, weather stations, robotics, and home automation. It is a practical choice when you need fast water detection in a DIY build.
Can this module measure exact water depth?
The product description focuses on detecting water contact and rising water levels rather than giving precision depth measurement specs. It is best treated as a threshold or presence sensor unless your own project testing and calibration show otherwise.
