General purpose load cell for weight sensing up to 5Kg (Size: 80 x 13 x 13 mm) – to buy additional Weight Scale Analog-to-Digital Converter (ADC) 24-bit board (HX711)
This straight bar load cell (sometimes called a strain gauge) can translate up to 5kg 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.
The load cell acts like a bridge, it has 4 colored wires as follows
- VCC: Red wire
- GND: Black wire
- Signal +: Green wire
- Signal -: White wire
