Sensitivity varies
Works well in low light, but direct sunlight interferes with the IR detection sometimes. Indoor use recommended.

Works perfectly with ESP32
Used this for a smart lamp project. Recognition is fast and accurate within 10cm. Very happy with the performance.

Compact and reliable
Small form factor fits nicely inside my enclosure. Detection is consistent and the module is well built.

Good sensor but needs 3.3V
Make sure you use a logic level converter if using with 5V Arduino. Otherwise great value for the price.
Q: What is the maximum detection distance?
A: The optimal range is within 15cm. Beyond that distance, reliability may decrease significantly.
Q: How many pins does it use?
A: It uses 4 pins: VCC, GND, SCL, and SDA for I2C communication.
Q: Is there a library for Arduino?
A: Yes, several open-source libraries are available on GitHub specifically for the PAJ7620U2 chip.
Q: Does this work with 5V logic?
A: The sensor operates at 3.3V. We recommend using a level shifter for 5V microcontrollers to ensure safety.
Q: Can it detect gestures in the dark?
A: Yes, it uses infrared light so it works effectively in complete darkness.
