Simple and effective

No complex libraries needed if you just want a simple digital input. Connect power, ground, and output, and it works immediately. Great for replacing mechanical buttons that wear out.

Solid component for the price

Used this in a student robotics project. It handled the voltage fluctuations well. The only reason for 4 stars instead of 5 is that the soldering pads are a bit small for beginners.

Great for hidden controls

I hid this behind a decorative tile to control my kitchen lights. It looks magical when the light turns on just by touching the tile. Very satisfied with the purchase.

Reliable capacitive switch

I've bought several of these for various prototypes. The response time is quick, and the LED indicator is helpful for debugging. Highly recommend for anyone getting into capacitive sensing.

Perfect for my smart lamp project

This module worked flawlessly behind a thin piece of acrylic. The sensitivity is adjustable and the self-locking mode is exactly what I needed for my bedside lamp conversion. Very easy to wire up with an Arduino.

Good value, minor sensitivity tweak needed

Works well overall. I had to sand down the back of the touch area slightly to get it to work through my specific wooden enclosure, but once calibrated, it's been reliable for weeks.

5 FAQ

Q: Can this module work through a 5mm thick glass panel?

A: Yes, in most cases, this sensor can detect touch through non-metallic materials like glass up to 5-8mm thick, depending on the specific dielectric constant of the material. You may need to adjust the sensitivity if your setup varies.

Q: Does the output stay high indefinitely when touched in self-locking mode?

A: In self-locking mode, the output toggles state with each touch. One touch turns it ON (high), and a subsequent touch turns it OFF (low). It does not require continuous holding.

Q: What is the maximum current this output pin can handle?

A: The output pin is designed for signal-level logic and should not be used to drive high-current loads directly. We recommend using it to trigger a transistor, MOSFET, or relay module for controlling higher power devices.

Q: Is this compatible with 3.3V logic boards like ESP32?

A: Absolutely. The operating voltage range is 3.3V to 5V DC, making it fully compatible with 3.3V microcontrollers such as the ESP32, ESP8266, and 3.3V Arduino variants.

Q: How do I switch between momentary and self-locking modes?

A: The module typically comes with a small solder jumper or pad on the PCB. Bridging or cutting this specific jumper changes the mode. Please refer to the pinout diagram included in the product manual for the exact location.
