PRHT-A1/RHT-A1 Temperature, Pressure & Humidity Sensors Description：

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 PRHT-A1 and RHT-A1 solve three requirements when measuring air quality:

1.Temperature and humidity measurement sensors must be kept away from heat sources

2.Temperature and relative humidity sensors should be next to the sensors to be compensated

3.The humidity sensor should respond as fast as the gas sensors
