Linear Capacitive Proximity Sensor

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...

Contactless Potentiometer – 12bit Rotary Position Sensor with Analog or PWM Output

Contactless Potentiometer – 12bit Rotary Position Sensor with Analog or PWM Output

This is an easy-to-program magnetic rotary position sensor with high-resolution 12-bit analog or PWM output. This contactless system measures the absolute angle of a diametric magnetized on-axis magnet. The project is designed for contactless potentiometer applications and its robust...
