Frequently Asked Questions

What is the operating voltage range for the PAJ7620U2 sensor module?

The module requires a supply voltage between 2.8V and 3.3V. Its I/O logic levels are compatible with 1.8V to 3.3V systems, making it directly usable with most 3.3V microcontrollers like ESP32 or Raspberry Pi without level shifting.

How do I communicate with this gesture sensor?

Communication is via the I2C protocol at speeds up to 400 kbit/s. You simply need to connect the SDA and SCL pins to your microcontroller, along with power and ground. The sensor provides gesture and proximity data through predefined registers.

What gestures does this module recognize?

It recognizes nine distinct gestures: moving your hand Up, Down, Left, Right, Forward, Backward, a clockwise circle, a counter-clockwise circle, and a wave. These are output as specific codes via the I2C interface for your firmware to interpret.

Can this sensor work in brightly lit environments?

Yes, it has high ambient light immunity, rated for conditions below 100,000 Lux. This allows for reliable operation both indoors and in typical outdoor daylight scenarios, though direct, intense sunlight should be avoided.

Does the module include proximity detection?

Yes, the PAJ7620U2 includes a built-in proximity detection function. It can sense an object's movement and approximate distance, which can be used for features like wake-on-approach to conserve power in battery-powered devices.
