PAJ7620U2 Gesture Recognition Sensor SKU: CQRSENSS001

PAJ7620U2 Sensor

Description

I am a gesture recognition module based on PAJ7620U2, which can directly recognize 9 basic gestures, supports I2C interface, and is compatible with 3.3V/5V level. Compared with APDS-9960 and other solutions, I have faster recognition speed, higher accuracy, more gesture recognition, and stronger anti-interference, which is suitable for low-power application scenarios such as smart home and robot interaction.
