Description

HX711 is an electronic scale module, whose working principle is to convert the measured changes in resistance value changes, through the conversion circuit into electrical output. The module communicates with the host computer through TTL 232.

This module uses 24 high-precision A / D converter chip hx711, is designed for high-precision electronic scale and design, with two analog channel input, the internal integration of a gain programmable amplifier 128. Input circuit can be configured to provide an electrical bridge bridge voltage (such as pressure, weight) sensor model is an ideal high-precision, low-cost sampling front-end module.
