●-The weight sensor cannot be used directly with RPi GPIOs or other MCUs. The HX711 breakout board is required, an ADC+PGA designed specifically for load cells. ●- Load sensor connection with hx711 board: red to E+, black on E, green on A+, white on A ●- The load cell can read a vibration of 1 gram (in the best condition), but can be influenced by many factors. ●-The weight sensor is particularly sensitive to temperature changes. So if you want a high level of accuracy, you need to insulate the load cell or store it in a place where it is not exposed to large temperature fluctuations. ●- To get a sampling rate of 80Hz from the hx711 module, you need to break the connection of PIN 14 to ground.
