1. Presenting Two types of Sensors Accelerometers & PIR Motion Sensors Presented by, Mouatasimur Rhaman Id: 201-115-146 & Safayet hosen Arman Id: 201-115-130

2. Contents PIR Motion Sensor & Accelerometer

3. PIR Motion Sensor

4. PIR stands for Passive infrared sensor. Detects Motion by sensing changes in temperature. Commonly used in security systems, lighting control, and home automation. What is PIR Motion Sensor ? PIR Sensor

5. WORKING PRINCIPLE OF PIR MOTION SENSOR 🛠️ PIR sensors have two components. Pyroelectric Sensor. Fresnel lens . The pyroelectric sensor detects changes in infrared radiation. The Fresnel lens focuses the infrared radiation onto the sensor working scenario.

6. Application & it’s Uses 👨‍💻 SECURITY SYSTEM . HOME AUTOMATION. DETECTION

7. ADVANTAGE OF PIR MOTION SENSOR 🛠️ Accurately Define The Object. Efficient. ADVANTAGE Doesn’t emit any radiation.

8. Accelerometer

9. Measures acceleration/ vibration in an object/ system. Commonly used in smartphones, gaming devices, & automotive systems. Can measure acceleration in three directions: X, Y, and Z. What is Accelerometer ? Sensor

10. HOW DOES IT WORK? ⚙️ Accelerometers work on the principle of Newton's second law of motion . They contain a small proof mass that is suspended by springs inside the sensor package. 4 Simple Steps When the sensor is subjected to acceleration, the proof mass moves relative to the sensor frame, causing a change in capacitance . This change is measured by the sensor electronics and converted into an output signal that represents the acceleration.

11. Measuring the Orientation in smartphones and gaming devices Monitoring Vibration in industrial machinery and structures Measuring acceleration and g - force in automotive system Application & it's Uses They are also used in Healthcare and sports applications to monitor physical activity and track movements. Accelerometers have a wide range of applications, including:

12. ADVANTAGE OF ACCELEROMETER 🛠️ Versatility Compact size ADVANTAGE High accuracy & Low power consumption Improved Safety
