In Star Trek, the crew of the Enterprise would routinely beam down to a planet, pull out their trusty tricorders and scan the environment for a multitude of different things, like gas levels and air quality.
Now you can have something like a tricorder for yourself. The Sensordrone Bluetooth Sensor has 11 sensors packed into a tiny housing that collects real data on your surroundings, and thanks to Cult of Android Deals, it’s just $149 for a very limited time.
