HMP155A is a high-performance temperature and relative humidity sensor. It adopts Vaisala's latest patented HUMICAP technology ® The 180R heated relative humidity probe, combined with advanced manufacturing processes, has excellent stability and strong environmental adaptability. With its new temperature probe with higher sensitivity and faster response, HMP155A can react to changes in ambient temperature at a faster speed, allowing you to have first-hand data on temperature changes at any time. HMP155A supports 0~1V voltage output and has good compatibility with the full range of CSI data collectors; It adopts energy-saving design and is only powered by the data collector during measurement. The power supply can be stopped when it is not working.

HMP155A temperature and humidity can be widely used in meteorological observation and forecasting, road environment monitoring, civil aviation, industrial testing and other fields. In order to enable the sensor to eliminate environmental influences for more accurate measurements and have a longer service life, we recommend that you equip it with a 41005-5 radiation shield or install it inside a louver box.
