History of sensors

The presentation taking about the sensors

1. History of sensors Eng. Abdalla Ali Abd El Manium Mechatronics

2. What are sensors? Who invented the first sensor? Types of the sensors Motion sensor History of sensors

3. A  sensor  is a device that detects changes in quantities. The specific quantity could be light, heat, motion, gases and pressure. It provides a corresponding output, generally as an electrical something that can be controlled. for example; a thermocouple converts heat into an output voltage. What is the sensor

4. Old Thermocouple (type K): used to measure the atmospheric temperature.

5. Most of the sensors in use today are be able to communicate with an electronic device. which is going to do the measuring, calculation and recording. Sensors are used in our life rapidly Applications for sensors; speedometer, parking sensor and fuel meter in cars. What is the sensor

6. Fuel meter (Analog) sensor: used to measure the level of fuel in the tank.

7. Speedometer (Analog) sensor: used to measure the instantaneous speed of a land vehicle.

8. Parking (Motion) sensor: used to alert the driver of unseen obstacles during parking.

9. It depend on the type of sensors. For type electric thermostat. The inventor is Warren Johnson .  This thermostat was able to keep temperatures within a degree of accuracy. that’s better than some of the low quality thermostats on the market today!  Who invented first sensor

10. *Warren Johnson

11. The first thermostat came to market in 1883, the first modern of sensor was manmade. Infrared sensors have been around since the late 1940s. Who invented first sensor

12. *The first manmade sensor motion sensor

13. The first motion sensor used for an alarm system. Came about in the early part of the 1950s, and the inventor was Samuel Bagno . His device made use of ultrasonic frequencies as well as the Doppler Effect. Who invented first sensor

14. Sensors have been around for various forms. Such as LDR, Temperature Sensor, Ultrasonic Sensor, Humidity Sensor, Vibration sensor, Gas Sensor etc.. Types of sensors

15. Types of sensors * Optical Smoke Detector (gas sensor) *Piezoelectric sensor (vibration sensor)

16. Types of sensors *Ultrasonic sensor *Light sensor

17. Types of sensors *(HS1101) HUMIDITY SENSOR *Motion sensor

18. Motion sensors improved in World War II. First use of motion sensor in the 1940s was by Samuel Bagno. And used to determined location of a person within a room. And then used to calculate the movement of the stars. Motion sensors

19. The first use in World War II with mine. Mines placed below the ground would explode when it sense movement on the surface. In modern technology it used at Radar to track enemy. And helps in air traffic control to avoid airplane accident. Motion sensor

20. Technological Concepts: Waves are sent out through the detector These waves are used to detect movement Once the waves hit an object, they are bounced back to the detector. The waves bounced back are taken in and encoded Motion sensor

21. The encoded information is then transmitted to the decoder. The information is then decoded. Decoded information is used to activate device. History of sensor

22. Motion sensor Then make calculation to determine the distance.

23. Advantage of motion sensor: Motion sensor has many advantage . Help to secure houses which detect any motion around the house. Motion sensors can help to increase energy savings such as by turning lights off in unoccupied rooms. Motion sensor

24. Disadvantage of motion sensor: Has made military more dangerous weapons. Used in mine explosive and rockets launcher. Motion sensor
