Gravity PAJ7620U2 Gesture Sensor

The DFRobot Gravity PAJ7620U2 recognises hand gestures at a distance of 3 to 20 cm and reports them via I2C. In fast mode it recognises 9 gestures, in slow mode 13. The module runs on 3.3 V and on 5 V and is connected via the Gravity connector.

Recommended Accessories:

• Gravity 4pin IIC/I2C/UART PH2.0 to Dupont Male Cable 30cm 10pcs
• Gravity IO Expansion Shield for Arduino V7.1

Features:

• Fast mode, 9 gestures: left, right, up, down, forward, backward, clockwise, counterclockwise, wave
• Slow mode, 4 additional gestures: slow left-right, slow up-down, slow forward-backward, random movement
• I2C via 4-pin Gravity connector, address 0x73
• Usable behind a cover made of glass or PC with more than 90 % transparency and less than 0.7 mm thickness, distance to the cover at most 0.2 mm (DFRobot)
• Library for Arduino and Raspberry Pi from DFRobot

Application Examples:

• Contactless remote control
