Digital Weight Sensor – Aluminum Alloy Load Cell (1kg 5kg 20kg)

The Digital Weight Sensor Load Cell is a precision strain gauge sensor designed to measure weight or force by converting mechanical pressure into an electrical signal. It features an aluminum-alloy straight bar structure with four strain gauges arranged in a Wheatstone bridge for stable and accurate measurements. The sensor operates with a recommended excitation voltage of 3–12V DC and provides a rated output of 1.0 mV/V. It offers reliable performance for weight detection, force measurement, and load monitoring in embedded systems. Ideal for digital scales, Arduino-based weighing systems, and automation projects. 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 = power+, green = signal+, black = power-, and white = signal-.
