All about Sensors

1. The Sensors & Various Types of Sensors

2. Sensors are devices that detect changes in the environment and send signals to other devices. They are used in daily life to make technology smart and automatic. For example, sensors allow smartphones, cars, and home devices to respond automatically, making life easier and safer. INTRODUCTION What are sensor?

3. Infrared (IR) Sensor Infrared sensors detect motion or presence using infrared light. They work by sensing the heat emitted by objects and can function even in darkness. Infrared sensors are commonly used in automatic doors and security alarms, helping to improve safety and convenience.

4. Proximity Sensor Proximity sensors detect objects nearby without physical contact. They work using electromagnetic fields or light. These sensors are used in mobile phones to turn the screen off during calls and in industrial machines to avoid collisions. By detecting objects automatically, proximity sensors make devices smarter and safer. Proximity Sensor proximity sensor. Slide 6 – Accelerometer and Gyroscope

5. Accelerometers measure acceleration and tilt, while gyroscopes measure rotation and orientation. Accelerometers are used in smartphones, fitness bands, and drones, whereas gyroscopes are found in game controllers and navigation systems. Together, these sensors help devices understand their movement in space, providing stability and accurate motion detection. Accelerometer and Gyroscope

6. Temperature Sensor Temperature sensors measure heat or cold using devices like thermistors. They are commonly used in thermometers and air conditioners to maintain comfortable temperatures. Humidity Sensor Humidity sensors detect moisture in the air. They are used in weather stations, greenhouses, and homes to monitor and control humidity levels. Temperature and humidity sensor

7. Pressure Sensor Pressure sensors measure air or fluid pressure. They are found in tire pressure monitors, barometers, and industrial machines to ensure safety and proper functioning. Smoke Sensor Smoke sensors detect smoke particles using light or ionization. They are essential in fire alarms and safety systems to alert people in case of a fire. Pressure and Smoke Sensors

8. Light Sensor (LDR) Light sensors measure the intensity of light in the environment. They are used in street lights and smartphones to adjust brightness automatically. For example, your phone screen becomes brighter in sunlight and dimmer in the dark, saving energy and making it easier to see. Image Sensor (CCD/CMOS) Image sensors convert light into electrical signals to create pictures or digital images. They are used in cameras and scanners. For instance, when you take a photo with your phone, the image sensor captures the light from the scene and turns it into a digital image you can see and save. Light sensor

9. Sensors play an important role in making devices smarter and improving daily life. They are now used in wearable devices, smart cars, AI robots, and medical devices. With the advancement of technology, sensors continue to develop rapidly, making devices more efficient, accurate, and intelligent. conclusion
