nature:
Hx711 ADC module 24-bit high-precision , TL431 external voltage regulator, uses an external voltage regulator (2.5V) as the excitation source and an external pressure sensor, the voltage is more stable.
This module uses 24-bit High-Precision A/D converter chip HX711, which is specially designed for high-precision electronic weighing scales. Two analog input channels and an integrated 128 times gain programmable amplifier. The circuit input can be configured to bridge the voltage. (such as pressure, weight), the sensor mode is a high-precision, low-cost sampling on the front of the module.
