The Person Sensor

At the size of a coin, this low-cost hardware module detects nearby peoples’ faces and returns information about how many there are, where they are relative to the device, and performs facial recognition.

Who, what, where, how?

The Person Sensor has built in facial recognition and determines how many people there are, as well as their relative position.


It is designed to be used as an input to a larger system, for example to wake up a kiosk display from sleep mode when somebody approaches, mute a microphone when nobody is present, or orient a fan so it’s always pointing at the nearest person.

Information is returned over a standard I2C interface, so it can be quickly and easily integrated into any embedded system.
