Description
HX711 AD Weight 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: 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 Simultaneous 50 and 60Hz supply rejection Current consumption including on-chip analog power supply regulator: normal operation Operation supply voltage range: 2.6 ~ 5.5V Operation temperature range: -40 ~ +85℃ PCB Size 35mmx20mmWeight Sensor: Four leads, easy to use 5-10V drive voltage applied, the force is directly output as a voltage change signal. Dimensions: 12.7mm * 12.7mm * 80mm Sensor through the screw hole at one end fixed and the other end to keep floating state, applying gravity following the direction indicated by label Particular attention must not directly push the white plastic cover part, so as not to damage the sensorConnection: Red to E+ Black to E- Green to A+ White to A- Package Includes: 1 X weight sensor 1 X HX711 module
