Transcript of "Introduction to sensors"

  1. 1. INTRODUCTION TO SENSORS PRESENTED BY CH.NAVEEN KUMAR
  2. 2. The following topics will be discussed:  What are sensors?  types of sensors  Types of micro-sensors
  3. 3. A sensor is a device that receives and responds to a signal  the signal could be heat,light,motion or chemical  a sensor coverts a signal into an analog or digital representation of the output  sensors detect and/or measure many different conditions What are some sensors that you have used? INTRODUCTION:
  4. 4. Humans are equipped with 5 different types of sensors Detects light Detects certain chemicals Detects pressure & temperature Detects sound
  5. 5. Basic Concepts Of Sensors:  Detect the presence of energy  Detects change in or the transfer of energy  Detect by receiving a signal than responding to that signal  Convert a signal into a readable output
  6. 6. Thermal sensors:  thermometer  Thermocouple gauge  Resistance temperature detectors(RTDs)
  7. 7. Mechanical sensors:  pressure sensor  Barometer  altimeter  liquid flow sensor  gas flow  accelerometer  aneroid barometer
  8. 8. Electrical sensors:  ohmmeter  galvanometer and ammeter  voltmeter  watt-hour meter
  9. 9. Chemical sensors:  oxygen sensor  carbon-dioxide sensor
  10. 10. Optical sensors:  photo detectors  proximity detectors  infra-red sensors
  11. 11. Other types of sensors:  acoustic wave sensor  seismometers  motion sensors  speedometers  geiger counters  biological sensors
  12. 12. Summary :  a sensor is a device that receives and responds to a signal  this signal must be produced by some type of energy,such as heat,light,motion or chemical
