The JDC AWS (Air Warning System) Weather Station measures windspeed, temperature and humidity with a sensor located at the end of a 2 meter cable. The AWS has alarm thresholds for warning of high windspeed, and high and low temperature and humidity. Two levels of windspeed thresholds can be set. The warning is both audible and visual. The kit includes the display, a 2 meter sensor cable, protection disk and wind turbine. The sensor cable has the temperature and humidity sensor inside. An optional separate wind sensor disk with 2 meter cable can be used to measure windspeed in a different location than temperature and humidity; useful for monitoring temperature and humidity in the shade, and windspeed in the open. ALARMS: User programmable alarms for windspeed, temperature, and humidity. There are two levels for each alarm, low level and high level maximum windspeed; low temperature and high temperature, low humidity, high humidity. High alarm sounds with a 1/2 second beep every second for 16 seconds. Low alarm sounds with a 1/4 second beep twice a second for 16 seconds. The bright LEDs flash during the alarm and continues until the alarm is reset. Oncer an alarm is activated, the display will show which alarms were triggered. The system comes with the display, sensor plate with 2m cable (includes temperature, humidity, and windspeed receiver), and wind turbine. Componants can be sold separately (special order).
