Metal Touch Sensor Module KY-036

SKU: FA3026 Tag:
Dimensions 3.5 × 1.5 × 2 cm
Operating voltage

3.3V ~ 5.5V

The module is an analog/digital sensor that uses a transistor to detect changes in electrical conductivity. When the transistor is touched with a finger, the conductivity changes and the module emits a digital and analog signal.

The digital output can be used a switch that changes state when touched. The analog output can measure the intensity of the touch. The detection threshold can be regulated using the on-board potentiometer.

This module consists of a transistor to detect touch, an LM393 differential comparator to control the digital output, a 3296W potentiometer to adjust the detection threshold, 6 current limiting resistors, 2 indicator LEDs and 4 male header pins. The module features analog and digital outputs.

Compatible with popular microcontroller boards like Arduino, Esp32, ESP8266 and Raspberry.

Connect the module’s analog output (A0) to pin A0 on the Arduino, and the digital output (D0) to pin 7.

Connect the module’s power pin (+) and ground (G) to 5V and GND respectively.
