Davis Instruments Vantage Pro2™ Aktiv DAV-6153EU Wireless digital weather station Max. number of sensors 8

The Davis weather stations Vantage Pro2 are the first and the only stations in their price range, which use the frequency hopping (FHSS) method for the wireless transmission. They transmit and receive data up to a line of sight of 300 m. This is the same as the length of 3 football fields! They maintain all the highest and lowest values (and/or totals or averages) for almost all weather variables of the recent days, months and years and their own weather forecast - everything without using a PC. They are equipped with an innovative, integrated sensor unit, which combines the rainfall collector, the temperature and humidity sensors as well as a wind meter in one device, which makes the setup of the device very easy and further improves the power and the reliability.
The Vantage temperature sensors have an accuracy of ± 0.5 °C and the accuracy of the outdoor humidity sensors is ± 3 %. In real situations, however, large deviations can occur through the incident sunlight and the heat reflected from roofs or from the road surface. The included irradiation protection shield (weather shelter) provides a substantial protection. Select the actively ventilated stations for an even better accurary - especially on warm, sunny days with less or no wind. A fan sucks the air through the sensor chamber and blows it out again above at the shield. This improved air flow helps achieve more exact temperature and humidity measurements. The effect of radiation heat and reflected heat is minimised and the conditions inside the weather shelter correspond to a large extent to the ambient air.
Set up your own customised weather station by adding one or more sensors. Each Vantage Pro2 weather station can receive data from eight different transmitting stations.
