HX711 module สำหรับ Load cell

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

Features:

     -  On-chip power supply regulator for load-cell and ADC analog power supply

     -  On-chip oscillator requiring no external component with optional external crystal

     -  Current consumption including on-chip analog power supply regulator: normal operation < 1.5mA, power down < 1uA

     -  Operation supply voltage range: 2.6 ~ 5.5V

     -  Operation temperature range: -40 ~ +8 C
