What is it used for?

Easy to use and great for microcontroller projects. These are leftovers after I bought a large bag of them and used one to monitor our basement sump pump. Easy way to tell if water level is rising or falling. Could be used to monitor anything with water levels like a fish tank. To use just attach one wire to GND and one wire to a digital pin and read the digital pin.
