Reliable and Compact

Used this in a prototype for a smart ventilation system. It fits easily into small enclosures and responds quickly to changes in air quality. Highly recommended for prototyping.

Solid performance for the cost

For under $10, you can't beat this. It's not industrial grade, but for hobbyist projects measuring relative PM2.5 levels, it does the job well. Just ensure you have a stable 5V supply.

Perfect for DIY Air Quality Projects

This sensor works exactly as described. I integrated it with an ESP32 to build a home air quality monitor, and the analog readings are consistent. Great value for the price.

Easy to interface with Arduino

Plugged it straight into my Arduino Uno. The sample code available online made getting started very easy. The output voltage correlates well with visible dust particles.

Works but requires filtering logic

The raw data can be a bit noisy. You definitely need to implement software averaging or filtering to get stable readings. Once tuned, it works fine for basic detection.

Good sensitivity, needs calibration

The module is sensitive to dust and smoke. However, you will need to spend some time calibrating the voltage-to-density conversion based on your specific environment. Documentation could be better.

5 FAQ

Q: What is the expected lifespan of the internal LED?

A: Under normal operating conditions with proper duty cycling, the internal infrared LED is designed to last for several years. Continuous operation without breaks may reduce its lifespan.

Q: Does this sensor output digital or analog signals?

A: This module outputs an analog voltage signal proportional to the dust density. You will need an ADC (like on an Arduino) to read the value.

Q: Can this detect cigarette smoke effectively?

A: Yes, the GP2Y1014AU0F is quite sensitive to fine particles found in cigarette smoke and will show a significant change in output voltage when exposed to it.

Q: Is a library available for Python or CircuitPython?

A: While we do not provide an official library, there are several open-source community drivers available on GitHub that support CircuitPython and standard Python for Raspberry Pi.

Q: Does this module come with a fan included?

A: No, this specific model (GP2Y1014AU0F) relies on natural convection or external airflow. Some breakout boards include a small fan, but this bare module does not.
