The HX711 module is a load cell amplifier breakout board for the HX711 IC that allows you to easily read and weigh the load cell. This module uses 24 precision A / D converter chips HX711. This is a special design for precision electronic scale designs with two analog input channels and is an internal integration of the 128X programmable gain amplifier.
The input circuit is an ideal sensing front-end module that can be configured to provide bridge-type pressure bridges (pressure, metering sensor mode, etc.), high accuracy and low cost. The
HX711 is an IC that allows you to easily integrate load cells into your project. No amplifier or dual power supply required. Simply use this board to easily connect and weigh any microcontroller.
The
HX711 uses a two-wire interface (clock and data) for communication. Compared to other chips, the HX711 has additional advantages such as advanced integration, fast response, immunity, and other features that improve overall performance and reliability. After all, it's one of the best choices for electronics enthusiasts. This chip reduces the cost of electronic scale while improving performance and reliability.
