About This Station

The station is powered by a Davis Vantage Pro 2 weather station with FARS (daytime fan-aspirated radiation shield). The data is collected in every 2.5 seconds and the site is updated in every 15 seconds. This site and its data is collected using Weather Display Software. The station comprises of an anemometer, a rain gauge and a thermo-hydro sensor situated in optimal positions for the highest accuracy possible.

Thermo-hydro sensor is mounted on a pole 1.6 meter high AGL (above ground level), 70 meter above sea level, facing south, on fairly open space. Anemometer is mounted on three and half meter mast located in the roof of garage, approximately in eight meter height. Surrounding trees and buildings distort somewhat wind speed readings.

Rain gauge is heated with a self-made heater. The heater is regulated with a double circuit thermostat, which measures outside temperature and temperature inside the rain bucket.

Weather Display runs in Windows 10 based HP Compaq Presario CQ57 notebook. Hardware is AMDŽ E-300 processor/1.3GHz with 4 GB memory. Power supply is secured with 700 VA UPS system.

UV and solar radiation (insolation) are measured with separate 1-wire sensors which are connected to HA7Net - Ethernet based 1-Wire Host Adapter. Insolation values are then collected with thermd application (perl program by Daniel Klein), stored in remote MySql database and finally shown in web. UV values are collected with owhttpd program, modified with perl application and shown via php page.

Sun sensors coupling caused an issue, RJ45 connectors are exposed to moisture and caused 1-wire bus short circuit. Now, sensors are mounted in a waterproof IP65 sealed enclosure and lead-ins are sealed with glue and liquid tape. RJ45 connector sealing is done using Amphenol Industrial Ethernet bayonet IP67 connector.
