I’ve set up a couple of Touch sensors however the threshold is too close so turns on/off constantly. So the idle state is around 5 When pressed it goes to about 4 Is there a way to make this threshold bigger?

Here’s my repo on GitHub . esp32_touch: setup_mode: false iir_filter: 15ms low_voltage_reference: 0.5V high_voltage_reference: 2.7V voltage_attenuation: 1.5V

Can you describe (or share a photo of) the physical setup of your touch sensors?

Hi Tom, Apologies… Sure. I’m basically trying to make a “bed contact sensor” (on the cheap :wink: ) - So I’m following something similar to this [image] ESP32 Capacitive Touch Sensor Pins with Arduino IDE | Random Nerd Tutorials Learn how to use the ESP32 Touch Pins with Arduino IDE. T…

Try constructing it like this: [image] Bed occupancy sensor, using parts you have Share your Projects! Hi everyone! This idea was posted somewhere in the forum. Unfortunately, I can no longer find the original thread. I thought the idea was so brilliant and tried it myse…

I tried that, but then the threshold goes really high and isn’t stable. For example it may stabilize around 750 but does fluctuate up and down +/- 10. Thus when trying to set the threshold, nothing is really stable.

I did a nija edit when I realised how you were using it.

This is the exact one I followed… BUT… -I only have two pads -Both pads go to one earth -Both pads have their own threshold (as I’d like “each side”) I was curious if I could put any resistors or anything similar on the Earth to widen the range a little?

Try increasing the separation between the plates.

This has also been done. I started originally with one plate and the wires connected to each side. I then changed to two plates, with a wire connected to each and the rear touching each other. This did increase the threshold, but not by much.

Wait, you have the gnd and touch shorted together? Don’t do that, just put the gnd plate really close to the sense plate. Like one width of paper away, but not actually touching.

Sorry Tom, no. I have a piece of A4 paper with foil partially covering one side - with the ‘Touch’ cable connected. Another piece of A4 with the same, but, the Earth connected. These are then placed ‘back to back’ within the ‘sleeve’ (not touching) When pressure is applied, the contact is going …
