Conductivity Sensor Switch
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
Hi, I bought a lot of this sensor for my Escape Room but they doesn't work how they promise
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
