The place where I am living (QTH: OL72CM) is Fanling in the new Territories which is close to Ta Ku Leng, close to the border. Ta Ku Leng experiences some of the most dramatic climatic changes here in Hong Kong, with the highest and lowest temperatures all year round recorded in this area. When I moved in I installed a wireless weather station with all the instrumental sensors installed on my roof for checking on humidity, temperature, wind speed and direction as well as precipitation and pressure etc. The weather station I choose was the Oregon Scientific WRM-968 Professional Wireless Station which has also RS-232 output from the sleek console to download data to my computer. Oregon has a software bundle for this package.
The Oregon Scientific WMR-968 Professional Wireless Weather Station is a sophisticated weather monitoring system designed to meet the needs of both amateur and professional weather enthusiasts! This state-of-the-art complete weather station comes equipped with outdoor sensors that operate on solar power, providing for easy installation. Indoors, the large display touch-screen console and separate baro-thermo-hygrometer rounds out the system.
Easy to operate, the Oregon Scientific WMR968 wireless weather station features indoor and outdoor temperature/humidity, wind speed and direction, rainfall range and rate, barometric pressure, dew point, wind chill, time and weather alarms, and much more! These weather stations also have seven wireless channels and accept up to three additional sensors.
