HX711 wiring

I used Olav Kallhovd's HX711 ADC library to control the module. You can download it directly from Github here or install it via the Arduino IDE library manager. HX711 Basic wiring Minimum connection of the HX711 to the Arduino UNO. The module can be operated with voltages between 2.6 and 5.5 volts. The module is < quite economical. Its power consumption is 1.5 milliamperes. The DT pin is connected to the Arduino Pin 4, SCK is attached to pin 5. You can choose other pins if you want In your instructions, the white wire Output+ (O+), Signal+ (S+)+ or Amplifier+ (A+) is connected to pin 3 (A-) in J1, which goes to pin 7 (INNA, Ch. A Negative Input) of HX711, and the green wire Output- (O-), Signal- (S-)+ or Amplifier- (A-) is connected to pin 4 (A+) in J1, which goes to pin 8 (INPA, Ch. A Positive Input) of HX711 To hook up the combinator board to the HX711 match the RED, BLK, WHT, and GRN pins Once you have the combinator board successfully soldered to the twelve wires, you can now connect it to the HX711 amplifier board via the 4 standard load cell wires. You can use short jumper wires or if you Most Load cell have four wires red, black, green and white. On HX711 board you will find E+, E-, A+, A- and B+, B- connections. Connect load cell. Load cell comes in various weights depending on your application select the load cell weight specification, In this tutorial I have used 40Kg, Precision Grade C2 load cell The HX711 is a 24-bit analog-to-digital converter which fits perfectly to weight scale applications. Fortunately, there exist many breakout boards for the HX711. Therefore, it is very easy to use it in combination with a so-called load cell. Load cells are transducers that convert pressure/force into an electrical signal

The primary components for this circuit are: Raspberry Pi 3 - Model B - ARMv8 with 1G RAM and HX711. Drag and drop these components onto the canvas, and instantly get a list of secondary parts, wiring instructions and a test code for your circuit. Try it for free 1. Connect the outer wires (white and black) of the load cell to the E+ and E- outputs of the HX711 module. E+ and E- are the power wires for the cells. The polarity doesn't matter. Switching will only invert the calibration parameter in the software. 2. Connect the middle cable (red) of the load cell to the A+ input of the HX711 module. 3. Connect two 1k resistors to the A- input of the HX711 module. Then the other ends of the resistors to the white and black wires

Wiring the Load Cell to the HX711 Module and Arduino 1. Connect the red wire to the E+ and the black wire to the E- output of the HX711 module. We chose the red and black... 2. Connect the green wire to the A+ and the white one to the A- inputs of the HX711 module. A+ and A- are the... 3. Connect. To use the HX711 with the bar load cell, we just connect the output wires White and Green to the A+ and A- pins. Then, we supply power or excitation to the bridge by connecting the Red and Black wires to the E+ and E- pins respectively: Notice that there is a B+ and B- pins on the HX711. This is for connecting a second Wheatstone bridge to it To make positive deflections of the cells combine to unbalance the Wheatstone bridge, wire one cell's white and black opposite to the other cell, and attach them to E+ and E-, with the reds connected to A+ and A- like this: HX711.E+ : Cell1.White + Cell2.Black HX711.E- : Cell1.Black + Cell2.White HX711.A+ : Cell1.Red Hx711.A- : Cell2.Re So if this is correct one Red wire would go to the A+, and the other to the A-, (of the Hx711 board). The connection of the other wires would be White and Black going to E+, and the other White and Black going to E-. The resistors shown as Active should be the ones that increase in value as the load cell is stressed. If the board happens to show a negative reading then swap the connections.

Viewed 446 times 1 \$\begingroup\$ in my project I use 3 wire load cell (like this (3wire 50kg) but mine are purchased from ebay) and HX711 for weighing. My wiring is like this (but i use Arduino mini pro 3V3): Apparently it should be a full-bridge circuit where the temperature is fully. A 3 wire is a load sensor not a load cell, so it doesn't have that wheatstone bridge in it, so it may be harder to read, which is why people usually hook 4 of them up with the combinator board and then the HX711. Your issue may be that it is much too small of a change to monitor with our code, or that the HX711 wants a wheatstone bridge hooked up to it

If the HX711 is plugged into the breadboard, we won't be able to wire it. Therefore, we'll actually place wires before the HX711. There are four connections for the HX711 on the side closest to the servo. Use a small piece of wire to run across the breadboard about five spaces. When we put the HX711 on top of the wires, we should still be able to plug other jumpers into the breadboard next to. Jul 3, 2018 - Out of all the interesting Arduino Projects we have worked on in the past, this turned out to be a little more exciting. Her Wiring issues: the wires to the cell may develop high resistance, e.g. due to corrosion. Alternatively, parallel current paths can be formed by ingress of moisture. In both cases the signal develops offset (unless all wires are affected equally) and accuracy is lost. Electrical damage: the load cells can be damaged by induced or conducted current. Lightning hitting the construction, or arc. Ok thanks a lot for the info, I will look into that. Ideally id like the least amount of components as possible to keep the foot print small. Currently I just have a PI, 4 HX711 connected to 22ga wire. Ideally just removing the wires would be best through some wireless module. - Ryan D Jun 12 '20 at 21:1
