Embedded IoT and AI Project Collection: Engineering Practices from Electric Vehicle Telemetry to Intelligent Monitoring

This article introduces an embedded IoT project collection covering electric vehicle telemetry, ESP32 device health monitoring, automation systems, and AI applications. It demonstrates the integrated application of IoT and artificial intelligence in engineering fields, providing valuable learning resources and engineering references from theory to practice for developers at different levels.

The Internet of Things (IoT) and Artificial Intelligence (AI) are two of the most active directions in the current technology field. Their combination has given birth to a new generation of intelligent systems, with application scenarios covering smart homes, Industry 4.0, and other fields. As hardware carriers, embedded systems undertake key tasks such as data collection and edge computing; the popularity of open-source hardware platforms like Arduino and ESP32 has lowered the development threshold, allowing more developers to participate in innovative practices.

1. Electric Vehicle Telemetry System

Real-time collection of Battery Management System (BMS) parameters, motor performance, and energy consumption data to implement fault diagnosis and predictive maintenance. Data is uploaded to the cloud via CAN bus communication and cellular/Wi-Fi.

2. ESP32 Device Health Monitoring

Use vibration, temperature, and current sensors to monitor device status. Perform signal processing and feature extraction via edge computing, and run lightweight ML models to achieve real-time intelligent diagnosis.

3. Automation System

Includes environmental monitoring, intelligent control, rule engine, and remote control functions, supporting custom automation rules.

4. AI-Driven Intelligent Applications

Covers scenarios such as image recognition (object/face/defect detection), voice interaction, predictive analysis, and anomaly detection.
