Good value, minor sensitivity issues
Great module for the price. It detects most gestures well, though sometimes struggles with very fast hand movements. Overall, a solid choice for prototyping.

Excellent I2C Integration
Seamless integration with my ESP32 project. The I2C address is standard, and the data output is clean. Highly recommend for anyone building touchless interfaces.

Reliable and Compact
The small form factor fits perfectly into my wearable prototype. Battery consumption is reasonable, and the detection range is consistent.

Best gesture sensor in this price range
I've tried several modules, and this PAJ7620U2 offers the best balance of performance and cost. The 9-gesture set covers all my application needs.

Easy to use but needs calibration
As a beginner, I found the setup straightforward. Had to adjust the sensitivity in the code for my specific enclosure, but once tuned, it works great.
Q: Is it compatible with Raspberry Pi Zero?
A: Yes, it is fully compatible with Raspberry Pi models including the Zero, as long as you connect it to the GPIO I2C pins correctly.
Q: Does this module come with a library for Arduino?
A: Yes, there are several open-source libraries available on GitHub specifically for the PAJ7620U2 that work seamlessly with the Arduino IDE.
Q: What is the maximum operating voltage?
A: The maximum operating voltage is 3.6V. Please ensure you do not exceed this limit to avoid damaging the sensor. It is 5V tolerant on the logic pins if used with a level shifter.
Q: How do I reset the sensor if it freezes?
A: You can reset the sensor by cycling the power or by pulling the RESET pin low for a short duration if your breakout board exposes that pin. Alternatively, re-initializing the I2C connection in code often resolves temporary locks.
Q: Can this sensor work in complete darkness?
A: Absolutely. The module has an integrated IR LED illuminator, allowing it to detect gestures even in total darkness.
