Can we help you?

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.
