Description

HX711 AD 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:
Two selectable differential input channels
On-chip active low noise PGA with selectable gain of 3264 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 controlsno programming
needed
Selectable 10SPS or 80SPS output data rate
Simultaneous 50 and 60Hz supply rejection
Current consumption including on-chip analog power supply regulator: normal
operation < 1.5mApower down < 1uA
Operation supply voltage range: 2.6 - 5.5V
Operating Temperature Range:-20 degree ~ 85 degree

50kg Load Cell
This load sensor, sometimes called a strain gauge, is the same one found in
digital bathroom scales (you know, the ones you use in January for your New
Year’s resolutions, and then forget about a month later).
The sensor is a group of half-bridge strain gauge, there are 3 ways to use it :
1. Use one sensor with an external resistor to form a full-bridge measurement,
the range of a sensor range: 50kg. External resistance on the higher
requirements.
2.Use two sensors to form a full-bridge measurement, measuring range for the sum
of the two sensors: 50kgx2 = 100kg
3.Use four sensors to form a full-bridge measurement, measuring range for the
sum of four sensors: 50kgx4 = 200kg
