Reliable Performance

Been running for 3 months straight in my ventilation system controller. No drift noticed so far and it handles dust spikes well.

Good Sensor, Tricky Wiring

The sensor itself performs well, but the pinout diagram was slightly confusing at first. Make sure to check the voltage requirements carefully.

Great for Home Station

Used this for my DIY air quality monitor project. The readings are consistent and match my commercial unit closely. Integration was straightforward.

Accurate Readings

Works well but needs a warm-up period of about 30 seconds before data stabilizes. Once running, it is very reliable for indoor monitoring.

5 FAQ

Q: What is the maximum cable length for data transmission?

A: For optimal signal integrity, we recommend keeping the connection cable under 20 centimeters when using UART communication.

Q: Can this detect cigarette smoke particles?

A: Yes, the sensor detects particulate matter in the 0.3 to 10 micrometer range, which includes smoke particles.

Q: What is the recommended warm-up time?

A: We recommend allowing the sensor to warm up for at least 30 seconds after power-on to ensure stable and accurate readings.

Q: Is this module compatible with Arduino Uno?

A: Yes, this module is compatible with Arduino Uno. You can connect via UART or read the PWM output signal using digital pins.

Q: Does this require manual calibration?

A: No, the module comes factory calibrated. However, we suggest checking zero point calibration annually for critical applications.
