## 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.  (https://www.amazon.com/Anndason-Pieces-Plastic-Switch-Liquid/dp/B072QCHQ2P/ref=sr_1_4_sspa?dchild=1&keywords=float+switch&qid=1618229140&sr=8-4-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzM0FSQlUyOVE1WkJQJmVuY3J5cHRlZElkPUEwMjc0MjUxMkFPVEpRUDNCWENNViZlbmNyeXB0ZWRBZElkPUEwNTg2MDAzMkYxRFdGTlo4NEFIQyZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=).

**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
https://www.amazon.com/dp/B07Z66RJWF?ref=myi_title_dp&th=1

**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.
