Mike Perrotta has combined a Neosensory Buzz wristband with an Adafruit Feather Bluefruit LE board and two Adafruit MLX90614 infrared thermometers to provide the ability to get haptic/vibration feedback when something is warmer nearby, like a person.

In the 1987 movie Predator, Arnold Schwarzenegger’s character fights an alien enemy in a dark, foggy rainforest.  They realize all too late the Predator has thermal vision and can track humans by sensing their body temperature.

Thermal vision isn’t reserved for sci-fi aliens: snakes, frogs, fish and mosquitos are among many animals that sense heat. What if you could join the ranks of these thermal-sensing animals? What if you could add temperature detection to your assortment of senses? Sensory expansion technology allows you to do this by passing temperature information to your brain via a separate sensory input.

The Feather board conveniently comes with onboard battery charging built in, so all that’s needed to charge the battery is to plug a micro-usb cable into your Feather. You’ll see a yellow light indicating that the battery is charging.
