5kg Load Cell with HX711 Amplifier Kit

A load cell alone is only half a weighing system - it outputs a signal in the microvolt range that needs a dedicated amplifier to become anything a microcontroller can read, which is exactly why this listing bundles the aluminium alloy 5kg load cell with an HX711 24-bit amplifier module and the DuPont wire kit to connect them, rather than leaving a buyer to source the amplifier separately and hope the wiring matches.

The load cell itself uses a standard strain-gauge bridge design rated to 5kg, with four lead wires wired directly to the HX711's differential inputs - the amplifier then converts that tiny analog signal into a stable digital reading over a simple two-wire interface to the microcontroller.

Common uses are DIY kitchen and postal scales, force-measurement projects, and any build under 5kg capacity where a load cell plus amplifier is the standard way to convert weight into a digital reading.
