Product description
Load cell amplifier based on the HX711 24-bit A/D converter. The module is designed for connecting Wheatstone bridge load cells and enables high-resolution measurement of weight and force. It is suitable for electronic scales, force measurement, industrial automation, and other applications where small resistance changes from a load cell need to be converted into digital measurement data.
The board connects easily to a microcontroller via a two-wire serial interface and features clearly labelled terminals for load cell power and signal connections. Using the accompanying Arduino library, the system can be calibrated to display measurements directly in units such as kilograms or pounds. The module features an open-source hardware design, and documentation is available for users who wish to customise the design to their own requirements.
