Stable performance over weeks
Been running this 24/7 for three weeks now. No drift in calibration observed yet. The build quality feels solid, and the connector pins are well-soldered.

Accurate readings, easy integration
I compared the PM2.5 readings against a professional grade meter, and they were surprisingly close. The UART protocol is straightforward to parse. Only minor issue is the fan noise at max speed, but it's negligible.

Reliable for industrial prototyping
Used this in a prototype for a warehouse monitoring system. It handles the environment well and the data stream is stable without packet loss. Excellent component for the price point.

Perfect for my home air monitor project
This module integrates perfectly with my ESP32 setup. The data output is consistent, and the added temperature and humidity sensors save me from buying separate components. Highly recommended for DIY enthusiasts.

Great value three-in-one sensor
Getting particulate matter, temp, and humidity in one small package is a game changer. The documentation provided by the seller was clear, and I had it running in under an hour.

Good sensitivity for dust detection
It picks up cooking smoke and outdoor dust very quickly. The response time is indeed fast as advertised. Would give 5 stars if the cable was slightly longer.
Q: How often should the sensor be calibrated?
A: For general environmental monitoring, factory calibration is sufficient for the lifespan of the unit. For high-precision scientific applications, we recommend comparing readings with a reference instrument annually.
Q: Does this module work with Raspberry Pi directly?
A: Yes, it works with Raspberry Pi. However, since the module uses TTL serial logic, you may need a USB-to-TTL adapter or connect via the GPIO UART pins with appropriate voltage level consideration.
Q: Can this sensor detect cigarette smoke effectively?
A: Yes, the laser scattering principle used in this module is effective at detecting fine particulate matter found in cigarette smoke, usually registering as elevated PM2.5 levels.
Q: Is there a library available for Arduino?
A: While we do not provide an official proprietary library, there are several open-source libraries available on GitHub compatible with Plantower-style sensors that work seamlessly with this module.
Q: What is the baud rate for the UART communication?
A: The default baud rate for this sensor module is 9600 bps. This can typically be configured via specific command frames if your application requires a different speed.
