Project Overview: The goal of this project is to build a system that can monitor weights using a Load Cell, process the data with an HX711 amplifier, and send SMS alerts via a SIM800L GSM module when the weight exceeds a predefined threshold. This can be particularly useful in applications such as industrial processes, smart agriculture, or even home automation.
Step-by-Step Guide:
Setting up Arduino Uno: Begin by connecting your Arduino Uno to the computer and installing the Arduino IDE. Ensure that the necessary libraries for HX711 and SIM800L are installed.
Connecting Load Cell and HX711: Properly wire the Load Cell to the HX711 amplifier and connect the HX711 to the Arduino Uno. This step is crucial for accurate weight measurements.
Configuring SIM800L Module: Connect the SIM800L GSM module to the Arduino Uno and configure the communication settings. This involves setting up the module to send SMS alerts.
Coding the Arduino: Write the Arduino code to read weight data from the Load Cell using the HX711. Implement the logic to trigger SMS alerts through the SIM800L module when the weight surpasses a specified threshold.
Testing: Upload the code to the Arduino Uno and test the system by placing various weights on the Load Cell. Ensure that the SMS alerts are sent as expected.
Finalizing and Troubleshooting: Make any necessary adjustments to the code or wiring to ensure the proper functioning of the system. Troubleshoot any issues that may arise during testing.
Conclusion: Building a Load Cell Weight Monitoring GSM Alert system using Arduino, HX711, and SIM800L is a rewarding DIY project that combines sensor technology with wireless communication. The versatility of this system makes it suitable for various applications, providing a practical solution for remote weight monitoring.
