Description:
HX711 Load Cell Conversion Module is designed for a high-precision electronic scale, with two analogue channel inputs and a 128 times gain programmable amplifier integrated inside. This module uses 24-bit high-precision A/D converter chip HX711.
The interface and programming between the chip and the back-end MCU chip is very simple. All control signals are driven by pins, and there is no need to program registers inside the chip.
HX711 Weight Module has the advantages of high integration, fast response and strong anti-interference, which reduces the overall cost of the electronic scale and improves the overall performance and reliability.
The input circuit of this module can be configured to provide bridge voltage (such as pressure and weighing) transmitter mode, which is an ideal high-precision and low-cost sampling front-end module
