Customer Reviews

Based on 3 reviews

The sensor is simple to use and understand and was compatible with the Arduino UNO3 board. Response was instant. Worked perfectly in our engineering project, the professor loved it.

There should be 2 versions.

Not very suited for auto-refilling function. Had to invert the output with a transistor.

Really good.

Really good sensor, sometimes à drop of water on it throws it off but otherwise great! Don't know why the external board doesn't have a pull-down resistor, but not a very big deal.
