The future is the Internet of Things, or so we’re told, and with that comes the requirement for sensors attached to the Internet that also relay GPS and location data. [Camilo]’s MobileNodes do just that. He’s designed a single device that will listen to any sensor, upload that data to the Internet over GSM or GPRS, and push all that data to the cloud.
The MobileNode is a small circular (7cm) PCB with a standard ATMega32u4 microcontroller. Attached to this PCB are GSM/GPRS and GPS/GLONASS modules to receive GPS signals and relay all that data to the cloud. To this, just about any sensor can be added, including light sensors, PIR sensors, gas and temperature sensors, and just about anything else that can be measured electronically.
Of course the biggest problem with a bunch of sensors on an Internet of Things device is pulling the data from the Internet. For that, [Camilo] designed a web interface that shows sensor data directly on a Google Map. You can check out the project video below.
how much could the price of the bom be reduced by dropping the gps bita. I mean, when not needing meter wide accuracy, isnt network localization ok? There are opendata soirces available for gsm tower locations, so all the node has to do is report cell tower id’s and transmit that.
by also mapping and sharing tower locations when placing a node, the used towers are thus always known.
About 15 bucks for the gps module in single digit quantities from what I saw. I’m surprised they didn’t use a combinations GPS/GSM chip like the SIM808
Might want to check out that GPS…
Lat -74.06, Lon 4.7.
That is not a map of a city in Antarctica.
I think that’s a result of PEBKAC. If you use lat: 4.718 Lon:-74.0686 you get Bogota.
