SparkFun Load Cell - 10kg, Straight Bar with Hook (HX711)

This straight bar load cell (sometimes called a strain gauge) can translate up to 10kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the bar. With this gauge you will be able to tell just how heavy an object is, if an object's weight changes over time, or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.

This particular load cell comes attached to hardware that ends with a hook. This allows you to easily install and hang your load cell.

Each straight bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 10kg. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation. The color code on the wiring is as follows: red = Exc+, green = Sig+, black = Exc-, and white = Sig-.
