Today in iLounge Deals you can pick up the Sensordrone for your iOS device for only $149. Featuring eleven different sensors in a single package small enough to fit on a keychain, Sensordrone lets you monitor the world around you for things such as carbon dioxide, temperature, gas leaks, light levels, weather, and more. An open platform and API also lets you connect external sensors for any other project you’re working on and have the data beamed back to your iPhone or other iOS device via Bluetooth.
