Chapter Content
- IoT-Based Vibration Monitor for RCC Beams
- Use accelerometer + NodeMCU + cloud dashboard
Detailed Explanation
This project involves creating a vibration monitoring system using an accelerometer, which measures the vibrations in Reinforced Cement Concrete (RCC) beams. The accelerometer detects the changes in movement, while the NodeMCU microcontroller processes this data and sends it to a cloud dashboard for real-time monitoring. Thus, engineers can observe the structural health and detect any anomalies quickly.
Examples & Analogies
Imagine a doctor using a heart rate monitor to keep an eye on a patient’s heart rhythms. Likewise, the vibration monitor acts as the doctor for the RCC beams, ensuring they remain healthy by alerting engineers to any unusual activity.

Chapter Content
- Crack Detection Using Drone and Computer Vision
- Image dataset + OpenCV + AI model
Detailed Explanation
In this project, students will use a drone equipped with a camera to capture images of structures. They will create a dataset of images for training the AI model. Using OpenCV, students can employ computer vision techniques to detect and analyze cracks in the captured images. This allows for quick assessment of structure health without needing to physically inspect every inch.
Examples & Analogies
Similar to how a security camera can identify intruders in a building, this drone project identifies cracks. Just as a camera captures footage to be analyzed later, the drone collects images for examination using advanced software, making inspections faster and more efficient.
