The HMP50 is a temperature and relative humidity sensor manufactured by Vaisala. It measures air temperature with a 1000 ohm platinum resistance themometer (PRT), and RH with a capacitive chip.

Features

PRT used for temperature measurement
Capacitive RH chip used for RH measurement
41303-5A radiation shield recommended when exposed to sunlight
A HMP50 housed in a 41303-5A can be mounted to a mast or crossarm
