6-Channel Capacitive Touch Sensor Module

https://www.electronics-lab.com/project/6-channel-capacitive-touch-sensor-module/

The module described here is a 6-channel capacitive touch sensor. The project is based on CAP1206 IC which contains six (6) individual capacitive touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor input is calibrated to compensate for system parasitic capacitance and automatically recalibrated to compensate for gradual environmental changes. […]
