GY-PAJ7620 Gesture Recognition Optical Sensor

Multi-Gesture Optical Telemetry: Powered by PixArt Imaging's PAJ7620U2 chip to recognize 9 distinct hand gestures including Up, Down, Left, Right, Forward, Backward, Clockwise, Counter-Clockwise, and Wave.

Dual Operation Modes: Features Normal Mode (60 Hz - 120 Hz sampling rate) for standard interaction and Gaming Mode (240 Hz) for high-speed motion tracking.

Built-In Proximity Sensing: Supports non-contact object proximity detection up to 20 cm, providing versatile touchless input for smart interface designs.

Low-Power I²C Digital Interface: Communicates seamlessly over standard I²C bus lines with integrated interrupt output (INT) to alert host controllers upon gesture recognition.

Onboard Voltage Regulator & Level Shifter: Operates across 3.3V - 5.0V power supply rails, ensuring full compatibility with Arduino, ESP32, and Raspberry Pi platforms.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with gold-plated contact terminals and integrated optical IR LED transmitter/receiver package.

Technical Specifications:

Operating Voltage: 3.3V - 5.0V DC.

Detection Distance: 5 cm - 20 cm.

Communication Interface: I²C Serial Interface (0x73 address).

Color: Purple PCB with Gold-Plated Solder Terminals.

Usage Advice: Connect VCC (3.3V-5V), GND, SCL, SDA, and INT to your microcontroller; keep the central optical sensor aperture completely unobscured by dark plastics or heavy glass covers.

Maintenance: Keep the optical lens area clean and free of dust, grease, or fingerprints; gently wipe using a soft, dry microfiber cloth.

Essential Touchless Control Interface: Position as a premium gesture-recognition transducer for touchless smart home switches, non-contact automotive consoles, interactive robot controllers, and arcade interfaces.

Highlight 9-Gesture Precision Sensing: Emphasize how integrated hardware-level gesture processing offloads motion analysis from the microcontroller CPU, simplifying code implementation.

Recommended Cross-Sell Add-ons: Pair with OPT3001 Ambient Light Sensor, GY-30 BH1750FVI Digital Light Intensity Illumination Sensor Module, TCST2103 optoelectronic switch photo interrupter, and ESD antistatic mat 50x40CM PCB Welding Mat.
