Load cell Click Board
Load cell click is a weight measurement click which utilizes a load cell element, in order to precisely measure the weight of an object. The Load Cell click 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 uses the HX711, a specialized 24bit analog to digital converter (ADC), designed for weight scale applications, made by Avia Semiconductor.
