The OVAL smart sensor is another crowd-funding project, this time on Indiegogo. OVAL is a smart, easy-to-use and versatile sensor that's designed to protect the people and things you care about most. Stick it, string it, or drop it in or on any object to detect any changes in motion, acceleration, light, moisture, temperature or proximity. If the sensor is disturbed, you'll receive an alert on your phone or email. Anywhere in the world. Instantly. The project has currently raised a little of half of their funding goal.
