Connect the five pins labelled RED, BLK, WHT, GRN, and YLW on the load Combinator board to the matching pins on the HX711. I bought a load sensor (SN-10245) with 3 wires (black, white, red) and I also bought the Load Cell Amp HX711 which need a 4 wires input. A goggle of the part number gave me zero. These are commonly colored RED, BLK, WHT, GRN, and YLW. Interfacing the HX711 with a 50Kg Load Cell; Interfacing the HX711 with a 50Kg Load Cell. The multimeter will register a change in voltage measured across the load cell’s output. (See page 10) NOTE: Moisture inside the junction box can cause unstable or drifting readings. I want to use only one load cell, but I saw on Internet that these load cell need another load cell to work. Load Cell. The stretched or upset WSGs are wired so that the positive or negative changes in resistance add up to a total upset of the bridge. Load cell output is measured using a digital meter. Depending on the model, the load cells may have a cable with 4 or 6 wires plus the screen. Additionally, a bridge resistance check will determine if there’s a short circuit within the load cell. I’m thinking about doing an independent project where it’ll probably require me to understand how weight scales work and maybe even build one. 1.4.Measure the voltage between SIG+ and SIG-. Compare the measurement values with the calibration certificate from the manufacturer to see if they closely match each other. Set the multimeter in DC millivolts and connect the output wires of the load cell to the multimeter. I'm trying to wire it up to my Arduino to detect changes in weight. They should be equal.
