EE181 air temperature and relative humidity sensor
EE181 is an accurate air temperature and relative humidity (RH) probe, which is very suitable for long-term unattended applications. It contains a proprietary coating on the RH element, which can increase the service life of the element and prevent the intrusion of dust, salt or other contaminants. The PRT temperature can measure the air temperature in the range of -40℃ to +60℃.
