A hands-on guide to building IoT and image processing projects with the Raspberry Pi. Starting with simple sensor circuits, the book progressively introduces cloud connectivity, real-time alerts, and computer vision — providing practical skills applicable to mobile development and electrical engineering as well.

Topics Covered

• PIR Motion Detection – Build a motion detection system with a PIR sensor and Raspberry Pi
• Gas Leak Alarm – Use the MQ2 gas sensor to detect explosive and fire hazards, with remote alerts
• IoT with ThingSpeak – Send sensor data to a free IoT server and trigger Twitter notifications
• Weather Station – Combine DHT11 (humidity/temperature) and BMP085 (barometric pressure) sensors with ThingSpeak for real-time weather alerts
• Digital Image Processing – Use OpenCV on the Pi to build object classifiers and video surveillance systems
• Machine Learning Basics – Object recognition and motion-based image manipulation

What You'll Learn

• Working with ThingSpeak to receive real-time alerts from sensor systems
• Processing sensor inputs with skills transferable to mobile and machine learning projects
• Incorporating sensors into projects for interactive, real-world feedback
• Building object classifiers with OpenCV
