Water sensor brick is designed for water detection, which can be widely used in sensing rainfall, water level, and even liquid leakage. Water Detector / Sensor Connecting a water sensor to an Arduino is a great way to detect a leak, spill, flood, rain, etc. It can be used to detect the presence, the level, the volume and/or the absence of water. While this could be used to remind you to water your plants, there is a better Grove sensor for that. The sensor has an array of exposed traces, which read LOW when water is detected.

Inputs
- GND – This is where you connect the low side of the voltage you are measuring. Caution! : This is the same electrical point as your Arduino ground.
- VCC: The is where you connect the high side of the voltage you are measuring
Outputs
- S: This connects to your Arduino analog input.
- – (or minus): This connects to your Arduino ground.
- : This is not connected. It does absolutely nothing.

The cable is easiest way ever to connect to your microcontroller/Raspberry Pi/WiFi router serial console port. Inside the big USB plug is a USB<->Serial conversion chip and at the end of the 36" cable are four wire - red power, black ground, white RX into USB port, and green TX out of the USB port. The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V level for interfacing with the most common 3.3V logic level chip-sets.
