Components You Need

To set up a Load Cell with ESP32, you typically need:

• Load Cell (5kg – 200kg) depending on application.

• HX711 Amplifier Module – Converts low mV signals to ESP32-readable digital output.

• ESP32 Development Board – Handles data processing, IoT connectivity, and display.

• Breadboard & Wires – For easy prototyping.

• Arduino IDE / ESP-IDF Libraries – For coding and calibration.

Wiring Guide: Load Cell + HX711 + ESP32

1. Connect Load Cell wires to HX711:

   • Red → E+

   • Black → E-

   • White/Green → A+/A-

2. Connect HX711 to ESP32 GPIO pins:

   • DT → GPIO 18 (example)

   • SCK → GPIO 19

   • VCC → 3.3V (ESP32 safe voltage)

   • GND → GND

3. Install HX711 Arduino Library.

4. Run calibration sketch with known weights.

5. Start reading live weight data.
