If when into the glass of water you are around 1.5-2.5Mohms you should add a transistor in your circuit.
Nevertheless could you explain the goal of using GS-WDS07 instead of off the shelves 433mhz leakage sensors?
I ordered a lot of such door sensors and I stayed 5 and thought of turning them into water sensors, I didn’t think it was that complicated.
Why are you going to add a transistor? What exactly would he do?
The transistor will act as an amplifier of the current detected when water goes through your sensor, it will let pass more current compared to the water sensor itself.
In my point of view for a security related device like a water detector I would go for off the shelves, just my thoughts.
There is something I do not understand, REED SWITCH is just a standard two pins switch, the water sensor I have is two-pin with two wires that once the water touches both legs is short-formed.
My question is why can it be used this way? Doesn’t water shorten?
I would love some circuit diagram for the transistor if you can of course
Your sensor is returning a too high impedance to replace the reed switch as it is.
1500 000 ohms cannot be handled electronically like 50 ohms.
any chance to get more info how to add transistor ?
i measure only the water and get 1.5M ohm and only the sensor is 40-50 ohm
Sorry but I don’t get it, could you be more accurate please:
-Water sensor impedance without water
-water sensor impedance with water
-reed switch impedance when close
-reed switch impedance when far
here is the reslt :
Water sensor impedance without water
water sensor impedance with water
reed switch impedance when close
and when reed switch impedance when far there is no measure (open circut) .
also the volt on 2 leg is
Hope now its OK…
You should measure the impedance between the blue and the orange I think?
ok, that’s clear
ok, seems like a wire contact
I did it, its doubled the result and its about 40-45 ohms
so any idea why its not working ?
Yes, to make it works you should build a circuit that generate an open switch when you have water and a close switch when you don’t have water.
You should better ask on a forum dedicated to electronics, you will have better chances to find support.
Did you figure out how to covert to Water sensor? I’m trying to do something.
After many trials I have answer for other DIYer who wants to do something, I finally got it. It was very simple, I will post proper answer with semantics soon.

Looks good! Did you measure power consumption on each state?
Any updates on power consumption?
Amazing !!!
I try it and its work . now no need to replace battery on 2-3 months on real water leak sensor.
