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.
