Sensor-Based Projects

Sensors are the eyes and ears of any electronic system. They convert physical phenomena like temperature, light, motion, and sound into electrical signals that microcontrollers can process. Our sensor projects teach you how to interface with a wide variety of sensors. **Types of Sensors We Cover:** - **Temperature Sensors:** DHT11, DHT22, LM35, DS18B20 - **Motion Sensors:** PIR (Passive Infrared), Ultrasonic HC-SR04 - **Environmental:** Soil Moisture, Rain Sensor, LDR (Light) - **Gas/Smoke:** MQ-2, MQ-7, MQ-135 - **Touch/Proximity:** Capacitive Touch, IR Obstacle Each sensor project includes detailed explanations of how the sensor works, wiring diagrams, and fully commented Arduino code.
