HX711 DIY Jewelry Digital Scale Kit For Arduino

HX711 module technical parameters:

HX711 is designed for high precision weighing sensor 24 A / D converter chip. Compared with the same type of other chip that integrates the peripheral circuits including power supply and on-chip clock oscillator which other similar types of chips needed.
With high integration, fast response, anti-interference and other advantages.
Reducing the overall cost of electronic scales and improve the overall performance and reliability.
The chip and the MCU chip interface and back-end programming is very simple, all the control signals from the pin drivers, doesn't need to programming the registers of the chip.
Input selector switch can be arbitrarily selected channel A or channel B, and is connected with its internal programmable low-noise amplifier.
Channel A programmable gain is 128 or 64, corresponding to the full amount of the differential input signal amplitude is ± 20 mV or ± 40 mV.
Channel B is fixed gain of 32 used for the system parameters detected.
Chip provides regulated power supply can be provided directly to the external sensor and chip A / D conversion, the system board doesn't need additional analog power.
The chip internal clock oscillator does not require any external devices.
Automatic power on reset function simplifies the initialization process to boot.

Features:

Two selectable differential inputs
Programmable gain is 128 or 64
Chip provides regulated power supply can be provided directly to the external sensor and chip A / D conversion
The chip internal clock oscillator does not require any external devices, if necessary, can also use an external crystal or clock
Automatic power-on reset circuit
Simple digital control and serial communication: All are controlled by the input pin, the chip registers don't need programming
Selectable output data rate is 10Hz or 80Hz

Note: As the temperature, environment, wire and other factors, so the actual error is about ±0.5g
