## Questions & Answers

**Q: I see 4 to 5 wires. Can you just power and the sensor will turn off(or on) power when liquid is no longer detected.**
A: It's an active sensor, so power must be applied to the power wire all the time for the output to activate. For a passive switch, you might consider something like a float switch that completes a circuit when the float goes up due to water.

**Q: If I use it for aquarium how it works?
I need to trigger an alarm when the water level comes lower than the sensor.**
A: Or you can drive directly your filing pump control.

**Q: Is there a version of this that works for metal containers ?**
A: yes, PLS refer the following type

**Q: will this work on the outside of 1/2" (13mm) OD silicone tubing ?**
A: I guess so : i’am using a 20mm silicone tube and it works fine. 
It also works when my finger get close to it : close from your 13mm diameter.

### ⭐⭐⭐⭐⭐ Working great
*by S***. on May 9, 2022*

Colsoned it on a 20mm pvc tube ans wired it directly on raspberry pi gpio (NPN version) working great. Already well tuned for my pool water level adjustment, but sensitivity can be adjusted if you need. Exactly what I was looking for.
