The sensor work even if only a terminal is touching (the positive)
What is wrong?

Hello,
I have the same problem. The module outputs a high signal when I touch only one terminal (the External Resistance +).
I connected the cables as shown on the example: https://wiki.dfrobot.com/Conductivity_Switch_Sensor_SKU__SEN0223
I tried with three different Conductivity Sensor Switch, always with the same result.
As it is, it doesn't measure the conductivity, it's a simple contact sensor.
Do you have any idea what is causing the problem?Thank you
mathieubauer 2017-10-13 02:59:08 That's wired, normally the module is not closed when A and B are not connected, do all the modules are like this? robert.chen
