This is a PAJ7620 Gesture Recognition Sensor.
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:
- Move up
- Move down
- Move left
- Move right
- Move forward
- Move backward
- Circle-clockwise
- Circle-counter clockwise
- Wave
Note: The breakout comes without solder of the header pin, the user will need to solder it manually
