Victoria ★★★★★ Oct 20, 2026

Took me about ten minutes to wire this up to my Arduino, and the low-level output triggers my buzzer instantly every time I touch the pad. Running it at 5V is dead simple, and the single channel keeps the wiring clean.

The LM393 chip makes this thing super consistent—every tap triggers the low signal exactly when I expect it. Hooked it up to a simple alarm circuit with 5V and it’s been flawless for a week straight.

I needed a simple touch sensor for a school project, and this module with the LM393 chip worked perfectly out of the box. The low-level output signal triggered my alarm circuit exactly as intended. Very happy with the reliable performance for the price.
