Metal Touch Sensor Module KY-036

The KY-036 metal touch sensor unit is a unit that detects human touch. It can be used as a touch button alternative to traditional mechanical buttons in interactive projects, control panels, or security systems. The unit relies on a Darlington transistor and provides two outputs: an analog output that reflects the strength of the touch or proximity, and a digital output that changes level when a certain touch threshold is exceeded, which can be adjusted via an integrated voltage meter. Technical details: unit model: KY-036, operating voltage: 3.3 volts to 5 volts, output type: digital and analog
