Gravity: PAJ7620U2 Gesture Sensor

Build an awesome interactive project with this PAJ7620U2 Gesture Sensor! It is an interactive sensor with 3D gesture recognition that can recognise 13 gestures at most within 20cm. The sensor offers stable performance, fast response and high accuracy, which makes it an excellent choice for interactive applications like non-contact remote controller, interactive robot, gesture-based game device, smart lighting management, and so on.

There are two recognition modes for this sensor: fast mode (9 gestures) and slow mode (13 gestures). In fast detection mode, the sensor can recognise 9 gestures: move left, right, up, down, forward, backward, clockwise, counter-clockwise, wave.The slow mode can recognise 4 expanded gestures besides the 9 basic ones: slowly move left and right, slowly move up and down, slowly move forward and backward, move randomly. The unit sampling time can be defined by users in this mode. Moreover, users can customise their own gestures if necessary.

Projects

• Project 1: Gesture Universal Remote-control
  With this remote control, we can control the electrical device by gestures. It also includes custom features, so it is theoretically possible to control all the electrical appliances controlled by the infrared remote control.
