Above is a set of typical sensors, We undertake tocustomize our systems for other types of sensors forany other aplication as per specific requirements.

The weather station is capable torecord data in regular scanintervals into an SD card or MMCcard. The data is stored inseparate files daily in Excelcompatible (.csv) file format. Thisinformation can be readily readby the software provided.

The weather stations can beinterfaced to GSM / GPRS basedmodems. These are to be suitablyenabled with SIM cards from aGSM service provider. The datafrom the weather station can besent in SMS, GSM dialup or GPRSpackets to a central computercollecting data. Multiple Weatherstations in various locations canbe linked centrally for datacollection and analysi’s by thesoftware. PSTN based dialup linksare also possible.

Communication networks thatcan be interfaced to theseweather stations are:• RS 485 / RS 232 based serial

links.• Ethernet links over LAN, VLAN,

and WIFI etc.• GSM / PSTN modems.Data can be centrally collected ina PC / server and stored in anyrobust Database application.The software can show graphson different timelines of weatherparameters. The software alsoshows windrose diagrams over atime period.

Special Features:• Solar Panel based power supply.• Additional Customized sensors compatible.• Large LED / Monitor based display systems

possible.• Internet browser based data display info.com
