TM7711 Weighing Sensor Module
Based on Avia Semiconductor’s patented technology, TM7711 is a precision 24-bit analogue-to-digital converter (ADC) with a built-in temperature sensor designed for weighing scales and industrial control applications to interface directly with a bridge sensor. This module uses TM7711 chip and converts the change in resistance into weight readings. The TM7711 has higher precision ratio compare to HX711. All you need is a load cell and microcontroller to build your very own Digital Scale.
