Measurement applications

The sensors are used to automatically detect and measure physical quantities. Sensor can read only analogue and computers can read only digital, so we need ADC(Analogue Digital Converter).

Why do we use computer to measure sensor instead of human?

  1. more reliable
  2. more accurate
  3. work longer
  4. response time
  5. frequency of reading
  6. automatic read
  7. safer
