Units for Humidity sensor____________

a) Dew/fost point or Relative Humidity
b) Relative Humidity or Parts Per Million
c) Dew/fost point or Parts Per Million
d) Dew/fost point or Parts Per Million or Relative Humidity

Answer: d
Explanation: Most commonly units for humidity measurement are Relative Humidity(RH), DEW/Fost point (D/F PT) and Parts Per Million(PPM). RH is a function of temperature. DEW/Fost point is a function of the pressure of the as but is independent of temperature and is therefore defined as absolute humidity measurement of temperature. PPM is also an absolute measurement.
