Excellent build quality
The casing feels robust and the pins are well-soldered. I've been running it continuously for two weeks without any issues. The PM2.5 detection is sensitive enough to catch cooking smoke instantly.

Good value for money
Works as advertised. The only minor issue is that the fan noise is slightly audible in a quiet room, but it's negligible for most applications. Great price point.

Perfect for my air quality monitor project
This D5 sensor module integrated seamlessly with my ESP32 setup. The UART communication is stable, and the readings match closely with my reference meter. Highly recommended for DIY enthusiasts.

Reliable data output
I logged data for a month and the consistency is impressive. No dropouts or erratic spikes. The documentation provided by the seller was also very helpful for getting started.

Accurate but needs calibration time
Great sensor overall. It takes about 30 seconds to warm up before giving stable readings, which is normal for laser sensors. Once warmed up, the data is very consistent.

Fast shipping and genuine product
Received the original authentic module quickly. Packaging was secure. Tested against a professional grade analyzer and the correlation is above 95%. Will buy more for our next batch of devices.
Q: What is the power consumption of the internal fan?
A: The typical operating current is around 100mA at 5V when the internal fan is running. Please ensure your power supply can handle this load.
Q: How often does the sensor need cleaning?
A: For optimal performance, we recommend checking the lens every 6 months. If used in very dusty environments, more frequent inspection may be necessary.
Q: Does this module come with a connector cable?
A: No, the module is sold without a cable. You will need to solder wires or use a compatible JST connector based on your project requirements.
Q: Is there a library available for Arduino?
A: Yes, there are several open-source libraries available on GitHub compatible with Arduino and ESP8266/ESP32 that support the D5 protocol.
Q: Can this sensor detect PM10 as well?
A: Yes, the D5 sensor detects particles in the range of 0.3 to 10 micrometers, so it can measure both PM2.5 and PM10 concentrations.
