12V DC Water Level Switch Sensor Controller Water Tank Tower Automatic Drainage
A part of the review has been auto-translated.
Fast delivery, good packaging, very good product.
As soon as received it I've powered it and put the three wires in water. It works as described. Common wire at the bottom of the tank, when the upper wire touches the water the relay toggles and then toggles back only when the lower wire is out of water. Adjusting the position of the wires you can easily choose the positions when starting to pump and stop. Of course if you want to feed a big pump with amps the relay is too weak and it'll be considered as a driver for a bigger one, but that's not a problem. It's a 5 stars device for sure!
