The module is based on a touch sensitive IC capacitive touch switch module (TTP223B).
In the normal state, the module produces Low power consumption. When a finger touches the corresponding position, the module output is high, if not touched for 12 seconds, it switches to low power mode. Digital Touch Sensor B21 features:
- Low power consumption
- Input voltage: 2 - 5.5VDC
- Can replace the traditional touch of a button - Four M2 screws diameter 2.2 mm that position the holes for easy installation
- 3-pin control interface:
1- GND
2- VCC
3- Control signal (output pin)
- Power indicators: Bright green LED when the sensor is on

It is very easy to make it work with an Arduino, PIC or any other microcontroller.
In its output pin we will be able to measure the PWM pulse width depending on the distance of the obstacle.
