Frequently Asked Questions

What is the I2C address of the PAJ7620U2 sensor module?

The default I2C address for the PAJ7620U2 sensor is 0x73 (hexadecimal). This address is used by the microcontroller to communicate with the module over the I2C bus. Ensure your code initializes the I2C communication with this specific address to receive gesture data correctly.

What voltage does the PAJ7620U2 module require? Can I use it with a 5V Arduino?

The module operates on a wide voltage range of 3.3V to 5V DC. It is fully compatible with both 3.3V and 5V logic systems, including 5V Arduino boards like the Uno. Simply connect the module's VCC pin to your board's 5V or 3.3V power rail, ensuring the logic levels match for reliable I2C communication.

What gestures can the PAJ7620U2 sensor recognize?

The sensor is pre-programmed to recognize nine distinct hand gestures: Up, Down, Left, Right, Push (forward), Pull (backward), Clockwise Circle, Counter-Clockwise Circle, and a Wave. It outputs a corresponding digital code for each detected gesture via the I2C interface, which your microcontroller can read and act upon.

Does the module come with headers soldered?

No, the module is supplied as a breakout board with an unsoldered set of header pins. You will need to solder the provided headers onto the board yourself. This allows flexibility for users who may prefer straight pins, right-angle pins, or direct wire soldering for their specific project enclosure.

Is any special library required to use this sensor with Arduino?

Yes, using a dedicated library (such as the 'PAJ7620' library available through the Arduino Library Manager) is highly recommended. The library abstracts the low-level I2C register commands and provides simple functions for initializing the sensor and reading gesture IDs, significantly simplifying the integration process.

Package Includes

  • 1 x PAJ7620U2 Gesture Sensor Breakout Board
  • 1 x Set of Header Pins (unsoldered)
