This module uses an A / D converter 24-bit high-precision type HX711.
It is a circuit specially designed for precision electronic scales with two analog input channels.
Amplifier gain is programmable.
The input circuit can be bridge configured (for pressure sensot in weighing mode).
It’s high precision and low cost and it’s the ideal module for the front-end sampling.
two differential input channel selectable.
Due canali di ingresso differenziali selezionabili
PGA Active On-chip, low noise with selectable gain of 32, 64 and 128
On-chip regulator, load cell supply and ADC analog power.
On-chip oscillator which doesn’t requires external components.
Simple digital control and serial interface: pin-driven controls, no programmation needed
Output data speed selectable between 10SPS and 80 SPS
Notch filter 50 and 60 Hz
Current consumption including analog power on-chip regulator: Normal functioning <1,5 mA,
Supply voltage: 2.6 ~ 5.5V
Compatible with external device for prototipation or MCUs like arduino, raspberry, pic, cortex ….
