6. Metal Detector

7. Thermal sensors and many more

8. Introduction to Meter Meters are used for real world measurements

9. Sound Meter

10. Heart Beat Measurement ECG

11. What you cannot measure Stress on the brain of human being Love Quantity of air in the atmosphere Water in sea No. of Fish in the sea Stars in the sky

12. Meter Application

13. Testing a Car Battery If the voltage of the car battery is below 12.5 V, it is required to recharge the battery. A fully charged car battery will read at least 12.6 V on the digital multimeter

14. Testing for continuity Testing of continuity helps in detecting broken wire, open wire, blown fuses, damaged diodes etc.

15. Sensors and Transducer Application

16. Ultrasonic sensors

17. Other applications involve detecting the presence of a person, and opening a door or detecting the presence of a car in a car wash station.

18. Detecting presence of materials Detecting presence of materials/objects is very important in automation industries Optical proximity sensors are used for counting boxes, breakage and jam detection

19. Proximity Sensors A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.sensor Inductive Sensors principle Capacitive Sensors principle

20. Detecting presence of materials Inductive proximity sensors are used to detect the presence of metals while Capacitive proximity sensors are used to detect metal and even non-metallic objects such as wood, paper, liquid and so on. However, the detection range of inductive and capacitive proximity sensors is very small.

21. Lab Activity-1 Objective To use multimeter for the following To test the battery and determine the percentage of battery To test continuity of power cord To test the light emitting diode

22. Lab Activity-2 Objective: To detect objects within a certain range using the ultrasonic sensors
