Features: Based on the PAJ7620U2 sensor, it can directly recognize 9 basic gestures and support gesture interrupt output. Built-in infrared LED and optical lens, can work in low light and dark environment. Support I2C interface communication, only need two signal pins to control. The onboard level conversion circuit is for 3.3V/5V logic levels. The recognition speed is fast, the accuracy is high, many gestures can be recognized, and the anti-interference is strong. It is suitable for low power consumption application scenarios such as for smart home and robot interaction.
