How do you connect 4 load cells to HX711?
You can connect four cells to a loop that forms a single scale unit:
- Form a loop by linking the same color outer wires (white and black) of the four load cells.
- Connect the middle cable (red) of one of the diagonals to the E+ and E- outputs of the HX711 module.
What is HX711 load cell?
Grove – ADC for Load Cell (HX711) The HX711 is a precision 24-bit analog-to-digital converter (ADC) that is designed for weighing scales and industrial control applications to interface directly with a bridge sensor. It is specially made for amplifying signals from cells and reporting them to another microcontroller.
What is the output of HX711?
1 is a typical weigh scale application using HX711. It uses on-chip oscillator (XI=0), 10Hz output data rate (RATE=0). A Single power supply （2.7～5.5V） comes directly from MCU power supply.
How do I merge 4 cells?
How to merge cells
- Highlight the cells you want to merge.
- Click on the arrow just next to “Merge and Center.”
- Scroll down to click on “Merge Cells”. This will merge both rows and columns into one large cell, with alignment intact.
- This will merge the content of the upper-left cell across all highlighted cells.
How do you apply F4 to all cells?
Either double-click on the cell or press F2 to edit the cell; then hit F4. It works even when you highlight multiple cells. F4 adds the dollar sign to the cell references you’ve highlighted.
How does the HX711 work?
HX711 is an electronic scale module, whose working principle is to convert the measured changes in resistance value changes, through the conversion circuit into electrical output. The module communicates with the host computer through TTL RS232.
How do I use HX711 as ADC?
How to use ADC?
- To activate the on-chip oscillator, connect pin14 to ground. The output data rate is 10SPS or 80SPS. Use a crystal across XI and XO pins to obtain an accurate data rate at the output.
- Pin11 and pin12 are used to retrieve data. The pin12 becomes HIGH, when data is not ready.
