PAJ7620 Gesture Recognition Sensor

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
