Water Level Sensor EW-W01 How to use

Postby JefferyS » Fri Mar 11, 2011 3:29 pm

Anyone have documentation or example circuit on how to use this water level sensor. I guess I should have found it first before buying it.

Thanks,

JefferyS

Well I'm feeling stupid :oops: It's just a magnetic switch, probably like the alarm switches where you put one with the magnet on the door and the reed switch on the door frame.

Anyway you can remove the bottom clip and flip the float over to use in the bottom or top of your liquid container or you can take the clip off the bottom and flip the float to make it a normally closed or normally open sensor.

If your going to run something that takes a lot of power, like a 120vac pump, you should use the level sensor to run a low power relay and let the relay do the connection for the high power stuff.

Hope this helps anyone that was wondering how this level sensor works.

Thanks,

JefferyS
