Some water sensors use the water itself to complete the circuit between two contact points. They will not be able to report dry. Others can.
Several community members have done various projects which use dry alerts, typically for pet water systems or Christmas tree pots. Here are some to look at.
As people have probably started to notice I do a lot for my pets… But that kinda just happens when you have to take care of 3 cats and a dog… Having things automated out helps a lot…
This project is related to an idea that I have had but am still working on. However I needed something for the mean time while I am still prototyping.
It is rather surprising how much water 4 pets can go through and how easy it is to overlook an empty bowl… So we moved up to a water fountain… However that didn’t really help either… I swear that they just kept drinking more…

I wanted to get alerts when my tree water was low…
I tried the Utilitech water sensor but it beeps when there is water.
I picked up a PEQ water sensor from Bestbuy and I made a small bracket on my 3D printer. I connected a wire to the 2 terminals on the water sensor.

I then zip tied the bracket to the tree at the height I wanted. Sensor hangs outside the tree.

I then used the No water app and I get push and SMS notification when my tree water gets low…works great.
I was also thinking about making the tree lights blink…but the Flasher app does not list moisture sensor as an option.

Hello,
I am thinking to use 1 or more Flood sensors like (eversprings) to measure water level in the ground water tank…
So I should receive a notification when the sensor dry (whish means the tank %50, %70 or %90 empty!!)
What do you think guys??
And any clue how to make it done??
Best,
