The Load Cell Click Board™ is a weight measurement Click Board™ which utilizes a load cell element, in order to precisely measure the weight of an object. The Load Cell Click Board™ can be used with the strain gauge type of load cells and can measure up to ±20V or ±40V of differential voltage. The strain gauge load cell is typically a circuit made of four strain gauges, connected in the Wheatstone bridge configuration. Very small voltage changes need to be accurately detected and converted into a digital form. Load Cell Click Board™ uses the HX711, a specialised 24-bit analog to digital converter (ADC), designed for weight scale applications, made by Avia Semiconductor.
