A simple, quick monitoring and reporting solution that can be used in extreme environments to alert and notify of changing weather conditions.

The FWS100 incorporates a WeatherHawk 520 weather station with a RF411 radio kit, SP2 solar panel mounted on a rapid deployment tripod. The sensors of the WeatherHawk 520  measure wind speed & direction, barometric pressure, solar radiation, rainfall, air temperature & relative humidity.

This rugged sensor system has no moving parts and includes an integral data logger, 3AHr battery pack & wireless 916 MHz spread spectrum radio. Accessories include a mast adapter for masts from 1.75-2.0 “ ID, a wireless base station w/power supply & antenna.

The Weatherhawk 520 are wireless to a host device (PC or server) using fully integrated industrial grade 916 MHz spread spectrum RF communications technology. They also have an RS232 serial data I/O located on the bottom of the weather station, which can be used as a second serial communications port, or for programming and testing the system, or for direct data downloads using a PC or PDA.
