PAJ7620 Gesture Recognition Sensor

Description

PAJ7620U2 integrates gesture recognition function with general I2C interface into a single chip. It can recognize 9 gestures and the gesture information can simply access via the I2C bus.

PAJ7620U2 also offers built-in proximity detection for the purpose of sensing object approaching or departing. The PAJ7620U2 is designed with great flexibility in a power-saving mechanism. The PAJ7620U2 is designed to operate from 2.8V to 3.3V over -40°C to +85°C and the pull-up voltage for the I2C bus and interrupt line is from 1.8V to 3.3V.

Gesture recognition function:

1. Move up
2. Move down
3. Move left
4. Move right
5. Move forward
6. Move backward
7. Circle-clockwise
8. Circle-counter clockwise
9. Wave

Note: The breakout comes without solder of the header pin, the user will need to solder it manually
