How to get rid of false positives of the touch capacitive switch?

Question

Electronics

I installed a lamp with a built-in touch (capacitive) switch in the bathroom (switching off / on when touched). False positives appeared almost immediately. Most often this happens when you turn on the exhaust fans in the bathroom and toilet.
I'm not an expert, but I guess it's all about pickups.
Tell me how to deal with this and where you can read about these issues intelligibly?
Thank you!

Answer 1

Lamp on batteries or from the mains? If from the network, then you can try to connect it through a surge protector.

Answer 2

Most likely, you need to add a tuning resistor to the circuit with the sensor and adjust it, maybe it is already there (often they are).
There are also different types of capacitive sensors, they work differently, some work if you apply it to anything, some only on human swings, you just need to adjust the sensitivity of the sensor.
PS In rooms with very high humidity, nothing can be regulated, capacitive sensors do not like wet rooms and constant random triggering occurs.

Answer 3

Maybe a ferrite ring? I read that it is just designed to filter out high frequencies (which is just short-term network interference).

Answer 4

The problem can be not only in pickups, but also in the contradiction "in the bathroom" "with built-in touch (capacitive)". capacitive sensors respond to changes in capacitance, and humidity sensors are the same capacitive
