Remote Unmanned Weather Stations

Remote Unmanned weather stations operate without the help of any human intervention in its activities. Such weather stations are ideal for remote places where dwelling is difficult or there is a shortage of experienced personals. For such an operation the weather station must be able to manage on its own, sensing of various parameters like temperature, pressure, humidity etc. The most important thing is to report the data to a central location where all the weather stations send their data. At this central location all the data from the various stations are analyzed and weather predictions are made. The task here is to send the data that we receive from the various sensors to a central location for processing automatically.

For this purpose we need a communication channel. We can use satellite, microwave, internet etc. But in all these types of communication channels the cost and the accessibility becomes an issue. To reduce the costs on infrastructure we are using a GSM network to communicate. We will be sending the data to our servers using a GSM modem either by SMS or by a GPRS connection. The data from the sensors is read into a micro controller and its framed into a particular format. Then this data is given to the modem for transmission through the GSM network.
