Measuring relative humidity and temperature of air in non-aggressive environment in air conditioning ducts, ventilations ducts, etc., can be done by the C-RQ-0400H-P sensor.
More detailed properties of the combined temperature and humidity sensor are listed in the chapter describing the C-RQ-0400H-P module.
