Measuring humidity in the environment with the risk of flowing water, condensation, etc., can be done by the C-RQ-0400I-xx sensor (xx - the cable length in dm), with the sensor mounted on the cable of the given length (max. 2m). The sensor can be placed in an environment with condensing moisture, dripping water, etc.


More detailed properties of the combined temperature and humidity sensor are listed in the chapter describing the C-RQ-0400I module.
