PAJ7620U2 Gesture Recognition Sensor Module for 3.3V Systems A compact gesture and motion detector module that adds touchless control to prototypes and smart home projects. Designed for 3.3V operation and compatible with common microcontrollers, this module recognizes multiple gestures to simplify interaction without physical contact. Key benefits Contactless control for cleaner, more durable interfaces and convenient hands operation. Simple integration with microcontrollers and single board computers for fast prototyping and deployment. Lowvoltage 3.3V compatibility reduces the need for level shifting when used with modern boards. Multiple gesture monitoring lets a single sensor handle a range of commands, reducing component count. Small form factor makes it easy to mount in enclosures or integrate into compact devices. Main attributes Function: Gesture recognition and motion detection for multiple gesture types.
