The LP-AWS is an advanced, portable, Low Power
Automated Weather Station built around the OWI-650
Low Power Weather Identifier and Visibility Sensor
(LP-WIVIS). The low power requirements of the OWI-
650 make it well suited for portable battery and solar
powered applications. The system has been designed
from the ground up for fast setup anywhere.
The OWI-650 measures visibility and detects rain, snow,
drizzle, freezing and mixed precipitation conditions The
OWI-650 is more than just a sensor. It is a system. No
separate data acquisition system is required to add
optional meteorological sensors. Implementing a
portable automated weather station with weather
identification and visibility sensor capability has never
been easier or as cost effective.
The fully automated OWI-650 provides accurate
visibility, present weather and precipitation
measurements. Typical systems include other optional
meteorological sensors including wind, pressure, and
temperature/ humidity sensors.
OSi's patented environmentally adaptive weather
identification algorithms use artificial-intelligence
technology derived from over 25 years experience and
over 200 million field hours of real-world data from OSi
sensors installed around the world. The result is the most
advanced / easily deployable Automated Weather Station
with optical weather identifier and visibility sensor
available. |
