DIYmalls Weight Sensor 20kg Load Cell Electronic Kitchen Scale + HX711 Amplifier AD Weighing Module for Arduino Raspberry Pi

Description

HX711 AD Weight Module
This module uses 24 high precision A/D converter chip hx711. It is a specially designed for the high precision electronic scale designwith two analog input channelthe internal integration of 128 times the programmable gain amplifier. The input circuit can be configured to provide a bridge type pressure bridge (such as pressureweighing sensor mode)is of high precisionlow cost is an ideal sampling front-end module.

Features:
On-chip active low noise PGA with selectable gain of 32, 64 and 128
On-chip power supply regulator for load-cell and ADC analog power supply
On-chip oscillator requiring no external component with optional external crystal
On-chip power-on-reset
Simple digital control and serial interface: pin-driven controls, no programming needed
Simultaneous 50 and 60Hz supply rejection
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 ~ +85℃
