Official Description

OSI's optical precipitation sensors measure rain and snow by detecting the optical irregularities induced within the sample volume by precipitation particles falling through a beam of partially coherent infrared light.


Recommended 2M off the ground, far from obstructions. Place as you would a standard rain gauge. There can be no obstructions normal to the sensor. NOTE: This legacy sensor is operating, but needs to be re-calibrated. Data from this sensor is not for research use. Please use the WxPro Weather station data.
