Meet Sensor-1: a portable security system that fits in the palm of your hand and lets you protect your valuable items. It detects real-time changes in motion and orientation and communicates with your smartphone or tablet. The device logs motion events when you are out-of-range. It has Bluetooth and iBeacon support.
Sensor-1 is expected to be compatible with iOS and Apple Watch devices. It can be armed based on proximity. The battery life lasts over a year. The project is getting funded on Indiegogo.
