Why Pair a Load Cell with HX711?

A load cell alone outputs a very small millivolt signal when weight is applied. This is too weak for microcontrollers to read directly. That’s where the HX711 amplifier comes in:

✔️ 24-bit ADC – High resolution for accurate weight measurement
✔️ Low Noise – Stable readings, minimal drift
✔️ Cost-Effective – Affordable for DIY & commercial applications
✔️ Wide Compatibility – Works with Arduino, Raspberry Pi, ESP32, STM32, etc.
✔️ Ease of Use – Simple 2-wire interface (DT & SCK)
