work fine, very sensitive

1 year review. Work as advertised. I have them under both a sheet of acrylic and thin cardboard and they still work fine. Observations. When configured as non latching they only stay on about 2 seconds when held. When configured as latching they output for extended periods. Very sensitive. You don’t actually have to touch to activate. Output is only 4v when operating on 5v which is fine for most logic circuits. Output switches between 4v and ground which is nice because I don’t need pull up or pull down resistors on the Arduino side of the circuit (recommend adding then anyway if your wire runs are long, mine are all less than 7”). However a few of them failed when supposed to output ground and had to be replaced, but that could be due to my initially poor soldering skills (which have improved considerably.) When configured for ground output the LED stays on when not activated. Finally you need to supply and attach your own headers, but that allows you to choose both the orientation and type of connection. I’ve soldered both wires and headers to them without issue, save for the possible failures mentioned above. Overall very satisfied.

No problems so far

Took a few tries to get use to. Doesn't pass enough current directly for a couple LEDs. However, it works WELL as a HIGH/LOW signal when using a logic level MOSFET. Not as well with NPN BJT because of the current required.The quiescent current when wired to project and off is 4.3uA, so totally satisfactory for a battery project.Active power (latched on, no project load) with board LED is 7mA.Board LED removed, current when on rises from 4.3uA to only 7uA, which is GREAT low power when active.I've only used the latching function, HIGH to turn on. Does in fact trigger without quite touching.They are SMALL, so if wanting a decent sized touch pad for other end users, look elsewhere and choose based in dmiensions.Otherwise, I'd recommend having these around to play with projects without using switches and buttons and dealing with debouncing with hardware or code.

Great sensor, very sensitive

Great little sensor, works very well. It does trigger when your finger gets about ¼" away from it. It does work through ⅛" glass. Jumpers allow you to select high or low TTL output as well as momentary or latching. LED indicator is a nice plus. Definitely would recommend.

Muy útil

El módulo es muy fácil de usar y muy versátil; fabriqué un circuito de 220vac con una fuente capacitiva para alimentar el módulo con 5v y luego a través de un optoacoplador y un Mosfet, sirve para para encender luces de 220v con una línea para tocar que lo activa.
