METAL & HUMAN BODY TOUCH SENSOR MODULE (KY-036)
Sensor-Arduino Metal and Human Body Touch:
- A transistor is used by the analogue/digital KY-036 Metal Touch Sensor Module to measure variations in electrical conductivity.
- The conductivity of the transistor varies in response to a finger touching it, causing the module to output an analogue and digital signal.
- A switch that changes states when touched can be used with the digital output.
- The touch's intensity can be determined using the analogue output.
- The on-board potentiometer can be used to control the detecting threshold.
- Compatible with widely used microcontroller boards, such as Raspberry, ESP32, Arduino, and ESP8266.
