Overview It is a very sensitive card that you can use to connect weight sensors to your microcontrollers. You can use it in your projects such as weight measurement, process control and weight detection.
HX711 has a simple two-wire communication interface. You can use any two pins of your microcontroller using the digital pin. for measurementWheatstone BridgeSince it uses this method, it can make very precise measurements. Connection names are written on the card according to the cable color codes used in most weight sensors. Although these connections may vary depending on each sensor, they are generally as follows:
- Red: Excitation+ or VCC
- Black: Excitation- or GND
- White: Amp+, Signal+ or Output+
- Green: Amp-, Signal- or Output-
- Yellow: Chassis
The yellow connection is used as the ground line to prevent electromagnetic interference.
Features:
- Working voltage: 2.7-5V
- Working current: <1.5mA
- Selectable SPS (samples per second) from 10 to 80
- 50 or 60 Hz power supply noise filtering
