🔌 TTP223 Capacitive Switch Self Lock Arduino: Enhance Your Electronic Projects Review

Great little sensor. Works great through 1/4" thick plastic, any thinner and it gets very delicate. Wanted to get away from mechanical snap action switches and this is the perfect alternative especially when used with anything Arduino based. A small piece of double sided tape will do to attach the sensor.

1. First of all I only received 5 of these sensors.2. Of the 3 sensors I tested, 1 has no main chip (just missing), 1 doesn't work. So far I have 1 working sensor, 2 dead sensors and 2 untested sensors. I could, but there are about 50 such sensors on eBay for this price and quality. I needed them fast so I chose Revain instead. Okay, but Revain sellers need to get better.

Update: I can't believe two batches of these units have failed in less than two months. It would be a compliment to call these switches trash. They might work for casual use but I can't tell if it's the frequency I use them or just how long they're plugged in, but they've all failed and lasted a minute. Original Review: I used these switches to make a non-clicking capacitive mouse, for which they worked great. about a month. Then, little by little, each switch began to freeze, and it still…
