When measuring air quality, gas, particle and VOC sensors must be compensated correctly for temperature
and relative humidity; PID and NDIR sensors also require pressure correction.
These sensors provide a simple digital solution for those environmental measurements and can be located
next to the gas sensors – an important solution to an air quality problem.
The RHT-A1 measures both temperature and relative humidity; the PRHT-A1 measures temperature and
relative humidity, plus barometric (absolute) pressure. Both sensors provide a digital, corrected output via an
I2C interface, direct to your microprocessor.
The PRHT-A1 and RHT-A1 solve three requirements when measuring air quality:
- Temperature and humidity measurement sensors must be kept away from heat sources
- Temperature and relative humidity sensors should be next to the sensors to be compensated
- The humidity sensor should respond as fast as the gas sensors
