[mircemk] shows how to create a simple non-contact proximity sensor using little more than ... that it’s possible to measure a capacitor’s capacitance using two microcontroller pins and ...

Well, think again, as [Limi DIY] retrofits the processing element onto a custom track, extending the calipers measurement distance to ... we’ll recall that the capacitance between two parallel ...

The line of capacitive proximity sensors with potentiometer adjustment for sensitivity allows sensing of metal and nonmetal objects through insulating materials, such as wood or plastic. They are ...
