DIY HX711 3kg Pressure Sensor Kit Weighing Sensor Brakcet Diy Electronic Scale Module

Description After installing the bracket sensor and single chip control board power on then the LCD displays 2 lines the first line is fixed as welcome to useThe weight is displayed at the beginning of the second line and the calibration parameters are displayed at the back if the AD module and the microcontroller are in poor contact the second line will not be displayed Because the bracket and the screws on it have weight each sensor will not display 0 grams when it is powered on for the first time At this time just press the tare button to adjust to 0 and then put a 50 grams For weights if the measured weight is larger than the actual weight increase the calibration parameter value If the measured weight is smaller than the actual weight reduce the calibration parameter value Take the sensor in this picture as an example the calibration parameter value is within the range of 676 687 and it is accurate to measure the weight of a 50g weight Therefore you can measure another standard weight and then take the intersection of the two calibration parameters so that the data measured later will be accurate If you measure two 50g weights that is 100g the calibration parameter value is within the range of 682 687 the measured weight is accurate so I can take 676 687 and 682 The intersection of 687 682 683 684 685 686 These numbers are the calibration parameters of this sensor Of course if you have conditions you can measure several standard t
