Meet the O2: a small and versatile Bluetooth device you can use to track your activity, monitor your sleep, keep an eye on your environment, and track your items. You can attach it near a window or door to get real-time temperature, humidity, and pressure data. Since the device is pretty small, you can wear it on your wrist or attach it to your bag to take it with you everywhere and track your activity. The device can track the steps you have taken, the distance you have run, and the number of stairs you have conquered. The O2 is also a sleep monitoring device.
You can attach your O2 to your valuable items and get notified when they are more than 30 feet away. The device is powered by a CR2032 battery (replaceable). The battery should last up to 90 days. The O2 is compatible with iOS and Android devices. You can find out more about it on Indiegogo.
