OSi - Model OWI-650 - LP-WIVIS - Low Power Weather Identifier and Visibility Sensors
From Weather Sensors
The OWI-650 LP-WIVIS has been designed from the ground up for quick deployment anywhere. The LP- WIVIS is the first present weather and visibility sensor designed for battery powered or solar powered applications. The LP-WIVIS is more than just a sensor. It is a system. Other sensors including wind, temperature, relative humidity, and barometric pressure may be easily added. The LP-WIVIS serves as both sensor and data acquisition system. No separate data acquisition system is required.

Product Details
The fully automated instrument provides accurate visibility, present weather and precipitation measurement in a single sensor. This next generation intelligent sensor uses all digital signal processing (DSP) for no-drift high-accuracy results. OSi's patented environmentally adaptive algorithms use artificial-intelligence technology derived from over 25 year's experience and over 200 million field hours of real-world data from our sensors installed around the world. The result is the most advanced/easily deployable weather sensor in the world.
The LP-WIVIS™ is already a low power present weather and visibility sensor but to further reduce the power requirements the LP-WIVIS™ may be operated in intermittent mode. In intermittent mode, the sensor is automatically powered up for one minute, reports present weather and visibility measurements and then is powered down. The heaters are independently controlled. In many environments the heaters are never powered on. Advanced detection algorithms report dew or frost on lens and control heater function.
The LP-WIVIS™ measures visibility and detects and quantifies rain, snow, drizzle, freezing and mixed precipitation conditions. The sensor is designed for year-round continuous operation in all climates from Antarctica to tropical rain forests.
Thanks to the advanced DSP electronics, the typical need for field calibration is completely eliminated. OSi Sensors are widely used by airports and regional DOT's across the US and throughout the world. No other present weather and visibility sensor can provide this powerful combination of high performance, low power, quick deployability and proven reliability! No other company can provide the proven level of support and customer satisfaction that OSi does!
Rechargeable batteries, solar power kits, spread spectrum radios, and additional sensors are all available options.

Optional Sensors
The OWI-650 LP-WIVIS can now serve as the data acquisition system for OSi wind, temperature / RH, and barometric pressure sensors to create a stand-alone automated weather station. Never before has an automated weather station with present weather and visibility capability been this affordable. Simply install the OWI-650 and connect the optional sensors to the OWI-650 Power Supply and Junction Box. All sensor information is combined into the serial output of the OWI-650. No other data acquisition system is required. Solar power kits and data radio options are available.
