The DFRobot HUSKYLENS 2 is a second-generation standalone AI vision sensor that runs seven machine learning algorithms — face recognition, object tracking, color recognition, line tracking, QR/barcode detection, object classification, and AprilTag detection — entirely on-device without any cloud connection or host processor. A press of the onboard button teaches the sensor a new face, object, or color in seconds, and results are delivered to Arduino or Raspberry Pi via UART or I2C in a simple, parseable format. The built-in 2-inch IPS LCD displays what the camera sees and what it has learned in real time.

FAQ
- Q: How do I teach HUSKYLENS 2 a new face? A: Point the camera at the face, press the learning button, and the sensor saves the face template to memory. Done in under 2 seconds.
- Q: Does it work with Arduino? A: Yes — use the DFRobot HUSKYLENS Arduino library. Read detected object coordinates and IDs with simple function calls.
- Q: Can it track multiple objects simultaneously? A: Yes — it can track multiple learned objects/faces and return individual IDs and bounding box coordinates.
- Q: Is Wi-Fi or cloud required? A: No — HUSKYLENS 2 runs all AI algorithms locally. No internet connection is needed.
- Q: What is the difference between HUSKYLENS 1 and HUSKYLENS 2? A: HUSKYLENS 2 features an upgraded processor, higher detection accuracy, faster inference speed, and additional algorithms including improved QR/AprilTag support.
