To simulate a load cell with an HX711 amplifier in Proteus, you need two separate types of libraries: the Proteus simulation model (for the schematic) and the Arduino IDE library (to write the code that will run in the simulation). 1. Download & Install HX711 Proteus Simulation Library

  1. Open Proteus ISIS.
  2. Open the "Pick from Libraries" window (Press 'P').
  3. Search for "HX711".
  4. If the installation was successful, the component appears under the "Results" list.

Recommended safe source: Search GitHub for "HX711" + "Proteus" and pick a repository with documentation and positive issues/comments.

Extract the Files: Locate the extracted folder. You should see two primary files: HX711Library.LIB and HX711Library.IDX.
