Metal Touch Sensor by ADIY
ADIY metal touch sensor module 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 variety of applications where touch sensing is required such as buttons, touchscreens and other human-machine interfaces.
Features: Metal Touch Sensor
- Operating voltage: 3.3 ~ 5.5V DC
- Adjustable sensitivity
- The output type is analog as well as digital
VCC input is connected to 3.3 - 5V DC.
DO (Digital signal output) is generated at the moment of contact detection.
AO (Analog output) directly measures value of the sensor unit.
Ground pin is connected to the ground.
Power LED turns ON when the sensor is supplied with voltage.
DO LED turns ON when the sensor detects a magnetic field.
