Metal Touch Sensor
The metal touch sensor module by ADIY is a type of switch that only operates when it’s touched by a charged body. It has a high-frequency transistor that can conduct electricity when receiving electromagnetic signals. The Metal Touch Sensor Module utilizes a floating lead on a Darlington transistor to detect a touch. There are 2 LEDs on board. PWR-LED lights when the module is connected to power. DO-LED lights when a touch is detected.
It is a simple module that can be easily integrated into a circuit. It can be connected to an MCU(microcontroller unit) using just three pins: VCC, GND, and DO. The signal pin goes high when the sensor is touched and goes low when the touch is removed. It can be used in a variety of applications where touch sensing is required such as buttons, touchscreens, and other human-machine interfaces.
