Further to the previous post, I opened a new post.
I have this GS-WDS07 433Mhz Door sensor and i want to connect instead the REED Switch a water leak sensor (2 pins only with cable).
So I dismantled the REED and measured its resistance and it came out at about 50 ohms, I tried to put a similar resistor but it immediately turned on the sensor, I also connected only the wires instead of the REED and tested with a glass of water but it did not activate the sensor. I only measured the resistance of the sensor and it gave 1.5M ohms and put it in a glass of water (obviously disassembled and not connected to the RF module) it gave me the same 1.5M ohms value sometimes cut to 2.5M ohms.
any idea how to make its work ?
