How To: Design Low-Cost Contactless Position Sensors

View full article: www.allaboutci...
In this video, we’ll demonstrate an inductive sensing technique used for contactless position sensing.
Conventional contactless position sensing methods, particularly Hall effect and magnetoresistive sensors, rely on magnetic fields. While these sensors are widely used, the magnets are costly, and they often need to be shielded from stray magnetic fields, which are particularly problematic in automotive and industrial applications where high currents in the wiring harness generate magnetic fields with the potential to interfere with these sensors. Inductive sensing is contactless, so it won’t wear out, it eliminates the magnet so it’s lower cost, and it’s immune to magnetic fields so it’s more robust. To demonstrate that, we have this evaluation kit for IDT’s ZMID5200 family of ICs, which includes the ZMID5201, the ZMID5202, and the ZMID5203.

I have the ZMID5201 but i did not order the ZMID COMBOARD. so i wonder if it's possible to program it without the comboard and if it has a default setting ?

Guys do u have same video with linear movement?

team, how much is permisible air gap minimum between metal and sensor

I'm looking for a flaks capacitor.

I'm a newbie at this so I apologize in advance if this is not the right place to ask this question. I looking for a ribbon type contact sensor that could detect the precise contact position of a non-metallic marble rolling across it. Or if there is a better way to do this, I'd consider it. Would need to cover a width of about 10-inches. Also, if there is a proper online forum for this, please refer me to it. I'll be using either a Rasberry Pi or Arduino. Thanks.
