Good value, fast response
I bought two of these to monitor different rooms. They react quickly when I cook or burn toast. The only downside is the fan noise is slightly audible in a quiet room, but acceptable for the price.

Works as advertised
Detects dust and smoke effectively. I noticed the readings spike immediately when lighting a candle nearby. Just ensure you provide a stable 5V supply to avoid erratic numbers.

Great addition to my weather station
Integrated this with my existing ESP32 weather station. The PM2.5 data adds a whole new layer of useful information. Very happy with the purchase and shipping speed.

Perfect for DIY Air Quality Monitors
This sensor module is exactly what I needed for my home automation project. The laser detection seems very accurate compared to my commercial unit. Setup with Arduino was straightforward using the UART interface.

Compact and efficient
Small form factor makes it easy to integrate into custom enclosures. Power consumption is low enough for battery-operated prototypes if you manage the sleep mode correctly.

Reliable data output
Used this for a university project on indoor pollution. The consistency of the data readings is impressive. Documentation could be better, but the community support fills the gaps.
Q: Is the internal fan replaceable if it stops working?
A: The fan is integrated into the module housing and is not designed to be user-replaceable. If the fan fails, the entire module usually needs replacement to ensure accurate airflow and readings.
Q: Does this work with Raspberry Pi directly?
A: Yes, but note that the Raspberry Pi GPIO operates at 3.3V logic while this sensor uses 5V. You will need a logic level converter for the RX/TX lines to communicate safely.
Q: What is the pinout configuration for the UART connection?
A: The standard pinout is: Pin 1 (VCC), Pin 2 (GND), Pin 3 (TX), Pin 4 (RX). Please refer to the datasheet for voltage levels; it operates at TTL 5V logic.
Q: Can this module detect cigarette smoke specifically?
A: Yes, the laser scattering principle allows it to detect particulate matter generated by cigarette smoke, which typically falls within the measurable size range of 0.3 to 10 micrometers.
Q: Does this sensor require calibration before first use?
A: The APM10 comes pre-calibrated from the factory. However, for high-precision applications, we recommend allowing a 30-second warm-up period upon power-up before reading data.
