AI02 SP&PIR
Features
Section titled “Features”This leaf is equipped with a piezoelectric speaker and a motion sensor. The piezoelectric speaker uses PWM and the motion sensor uses I2C to connect to the MCU leaf. The motion sensor has a built-in proximity detection algorithm and can detect proximity with simple settings and can output an interrupt signal when proximity is detected.
