Proximity Detection Range with CapSense
Question: What is the maximum distance for proximity detection and what is the femto F capcitance do you expect to detect at that range?
Response: The range of 22cm for proximity detection is a best case number. This is achieved with the CSD user module set to slow scan speed and highes resolution. The target is a large hand. Test location is in a lab with no interference sources. The signal produced is near the noise floor of our device, which is around 10fF.
