HX711 Weighing Sensor Dual-Channel 24 Bit Precision Module Arduino

Description :

• 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.
• The input circuit can be configured to 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: 

• Two selectable differential input channels 
• On-chip active low noise PGA with selectable gain of 32, 64 and 128 
• On-chip power supply regulator for load-mobile and ADC analog power supply 
• On-chip oscillator for which no external component with optional external crystal 
• On-chip power-on-reset 
• Simple digital control and serial interface: pin-driven controls, no programming required 
• Selectable 10SPS or 80SPS output data rate 
• Simultaneous 50 and 60Hz supply rejection 
• Power consumption including on-chip analog power supply regulator: normal operation <1.5mA, power down <1uA 
• Operation of supply voltage range: 2.6 ~ 5.5 V 
• Operation temperature: -40 ~ + 85 °
