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.

Description:
- The dimensions: 32mm x 14mm approx
- The working voltage: 3.3V-5V DC
- On-board LM393 voltage comparator chip and vibration sensing (generally SW-18010P) probe.
- Sensitivity adjustable (fine tune) using potentiometer.
- Can be used to detect vibration and other occasions.
- On-board output signal indication LED, effective output signal is high level, and the same time the indicator LED turns on.
- Output signal can be directly connected to the microcontroller I
-
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.

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.
