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.
