Designed and implemented an IoT-based battery temperature monitoring and alert system using Cisco Packet Tracer. The system employs an MCU controller and a temperature sensor to continuously monitor battery temperature and automatically activate visual and audible alerts when abnormal conditions are detected, demonstrating basic IoT and embedded control concepts.

Objectives

• ▪ Develop a simple IoT-based battery monitoring prototype.

•  Interface a temperature sensor with an MCU controller.

• Process sensor readings using JavaScript programming.

• Trigger warning devices when the temperature exceeds a predefined threshold.

Outcomes & Contributions
