HX711 Weighing Sensor Module Dual-Channel 24 Bit Precision A/D Module Pressure Sensor Board for Arduino DIY Electronic Scale

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. Theinput circuit can be configured to provide a bridge type pressure bridge (such as pressure, weighing sensor mode), is of high precision, low cost is an ideal sampling front-end module. Feature: 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-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 Selectable 10SPS or 80SPS output data rate Simultaneous 50 and 60Hz supply rejection Current consumption including on-chip analog power supply regulator: normal operation < 1.5mA, power down < 1uA Operation supply voltage range: 2.6 ~ 5.5V Operation temperature range: -40 ~ +85 Degrees Celsius Package Included: 1 * HX711 Weighing Sensor Dual-Channel 24 Bit Precision A/D Module Pressure Sensor
