Good quality, needs calibration
The module works well once you understand the solder pads for configuring sensitivity and output mode. Documentation could be clearer, but it's a solid component.

Works as advertised
Simple plug-and-play if you know your way around a breadboard. The momentary mode is exactly what I needed for my reset switch.

Perfect for Arduino Projects
These sensors work flawlessly with my Arduino Uno. The response is instant and the sensitivity is just right for a simple touch button. Great value for the price.

Reliable and Compact
I used these for a custom control panel project. They are small, easy to mount, and very reliable. No false triggers detected so far.

Excellent sensitivity
Even works through a thin plastic case. Very impressed with the detection range and stability. Will definitely buy more for future builds.

Great for learning electronics
Bought these for a university project. They are inexpensive and perfect for prototyping capacitive touch interfaces without complex coding.
Q: How do I switch between momentary and toggle modes?
A: You can change the output mode by soldering the specific configuration pads on the back of the PCB. Please refer to the datasheet included in the product images for the exact pad locations.
Q: Does the package include headers for soldering?
A: The module usually comes with pins unsoldered to allow for flexible mounting options, but some batches may include a 3-pin header strip. Please check the specific listing images.
Q: Is this compatible with 3.3V logic systems like ESP32?
A: Absolutely. The operating voltage range is 2.0V to 5.5V, making it fully compatible with both 3.3V and 5V microcontrollers including ESP32, ESP8266, and Arduino.
Q: Can this module detect touch through glass or plastic?
A: Yes, the capacitive sensor can typically detect touch through non-conductive materials like glass or plastic up to 3-5mm thick, depending on the material density and configuration.
Q: What is the maximum current this output pin can source?
A: The direct output current is approximately 8mA when high. For driving higher load devices like relays or bright LEDs, we recommend using a transistor or MOSFET driver circuit.
