Linear Capacitive Proximity Sensor
https://www.electronics-lab.com/project/linear-capacitive-proximity-sensor/
The project presented here is an analog capacitive proximity sensor. The circuit is from Texas Instruments application note. Most conventional capacitive proximity sensors produce a “1” or “0” output, this circuit produces a DC output that is a function of the size and relative permittivity of an object passing between the sense capacitor plates. Different […]
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. […]
