Compact and effective

The size is perfect for fitting into small enclosures. I integrated this into a robot arm control panel, and it looks professional. The digital output makes coding very straightforward.

Sensitive to noise

It works well in a controlled environment, but I found it sometimes triggers falsely if there is electrical noise nearby. Adding a capacitor helped stabilize it. Good for simple projects, maybe not for industrial use.

Easy for beginners

As someone new to electronics, I found this incredibly easy to set up. There are plenty of tutorials online for this specific module. It triggered my LED strip exactly as expected when I touched the pad.

Reliable and consistent

We bought ten of these for our workshop classes. All of them worked out of the box without any dead pixels or connection issues. The build quality is solid for the price point.

Great value, minor wiring confusion

The module itself is high quality and very responsive. I deducted one star because the pinout wasn't clearly labeled on the board itself, though the documentation online was helpful. Works great with Raspberry Pi GPIO.

Perfect for my home automation project

This sensor works flawlessly with my Arduino Uno. The sensitivity is easy to adjust using the small potentiometer on the back. I used it to create a touch-sensitive lamp, and the response is instant.

5 FAQ

Q: Can this module be powered directly by a 5V USB source?

A: Yes, the module operates within a 3.3V to 5V range, so connecting VCC to a 5V USB power source and GND to ground will work perfectly.

Q: Does this come with the jumper wires needed to connect to an Arduino?

A: Yes, the package includes a set of female-to-female jumper wires specifically designed to connect the module's 3-pin header to standard Arduino boards.

Q: Is this compatible with the Raspberry Pi Pico?

A: Absolutely. Since the Pico supports 3.3V logic and this module accepts 3.3V input, you can connect the SIG pin directly to a GPIO pin on the Pico.

Q: How do I adjust the sensitivity if it triggers too easily?

A: There is a small blue potentiometer on the back of the PCB. Use a small screwdriver to turn it counter-clockwise to decrease sensitivity or clockwise to increase it.

Q: What is the maximum current this sensor can switch?

A: This is a signal sensor module, not a power relay. It outputs a low-current digital signal (typically <20mA) intended to be read by a microcontroller, not to drive high-power loads directly.
