Good but needs tuning
Works well but I had to adjust the sensitivity pad for my thick plastic case. Otherwise solid.

Reliable Touch Switch
Used this for a lamp control project. The latching mode is very stable and does not drift over time.

Plug and Play
No complex libraries needed, just digital read. Highly recommend for beginners starting with sensors.

Great for DIY Projects
Works perfectly with my Arduino Uno. Very sensitive and easy to wire up for basic touch controls.
Q: Can I connect multiple modules to one board?
A: Yes, each module requires one GPIO pin. You can chain as many as your controller supports.
Q: How do I change the mode to latching?
A: There is a solder jumper on the back of the module to switch between momentary and latching modes.
Q: Does this come with header pins for breadboard?
A: Headers are not included by default, so you may need to solder pins for breadboard use.
Q: What is the maximum input voltage allowed?
A: The module supports up to 5.5V, but 3.3V or 5V is recommended for most microcontrollers.
Q: Can this sensor work through a glass panel?
A: Yes, it can detect touch through non-conductive materials like glass or plastic up to a certain thickness.
