  • I'm trying to make a capacitive flood detector and I've run into a problem. I'm applying power to the sensor, waiting 100ms then reading the OUT pin; the process repeats every 5 minutes. Here is the issue I'm experiencing: if my finger (or anything else with high relative permittivity) is on the sensor pad before I power on the sensor, the OUT pin never changes to high; I've confirmed the behavior with my oscilloscope. If I power on the sensor, then touch the pad it works fine. Any idea what's going on?

No public wish lists :(
