Hello,

We created a design using the Cy8cmbr3116 chip.

We made PCB production.

Hand detection distance 2 cm.

Antenna size appears in the diagram.

How can we increase this distance?

I ask you to help

Best

Hi MuMu_4440751

The Proximity distance in any CapSense design will be roughly equal to the diagonal distance of the Proximity loop. In your design, to increase the proximity distance, you can increase the size of the loop.

Additionally, you cal also enable Advanced Low-Pass filter (ALP) in Ez-Click to obtain increased sensing distance. Please refer the ALP Filter Tuning section in MBR3 CapSense Design guide​, page 85.

Best regards

Hari
