Sensors

The minimum required components of a sensor are:

  1. Power
  2. Processor
  3. Sensor
  4. Communicator

Types of Sensors

Based on how they work

  1. Active vs Passive
  2. Invasive vs non-invasive
  3. Contact vs no-contact
  4. Absolute vs Relative

Another way to categorize them

Based on where they are used

Which industry, context.

Based on how they measure

the mechanism behind their measurement

Based on what they

  1. Optical: Machine Vision
  2. Humidity
  3. Pressure of air
  4. Flow of liquids
  5. Proximity and Position
  6. Acoustic, Sounds, Vibration
  7. Acceleration, Tilt
  8. Temperature
  9. Motion, Velocity, Displacement
  10. Electric, Magnetic
  11. Gas and leaks
  12. Chemical
  13. Biosensors
  14. Biological metrics of our bodies

Another way (again)

Based on what they measure (in general)

  1. Biosensor
  2. Physical
  3. Chemical
