hello,
I am using the Capacitivesensor.h library for a water level sensor. It works.
So when water touches the homemade probe. A realy is activated.
One issue is during testing I noticed that if the containor was full (relay ON) and the power was turned off
On start up the capacitance is read at a low level . For instance if the realy was on and there was a power shortage. when the program would go back on the relay should be on but it wasnt.
It acted like the the water was not touching the probe.
If I lower the level then raise it back to touching the it reacts like normal.
I am thinking I need somesort of programed on off to trigger it like I am doing manually. Doees this make sence ??
Thank
J
