Accurate and robust
Been running this 24/7 for three months now. No drift in calibration detected. The build quality feels solid and the connector pins are sturdy.

Excellent precision for DIY air monitors
I integrated this sensor into my home automation system and the readings match my commercial-grade monitor almost perfectly. The UART communication is stable and easy to parse.

Great value, fast response
Very responsive to changes in air quality. I tested it by burning a piece of paper nearby and it spiked immediately. Only giving 4 stars because the documentation could be more detailed for beginners.

Good sensitivity
Notices even slight dust increases when cooking. The fan noise is minimal. Just make sure you provide a stable 5V power supply to avoid reading fluctuations.

Reliable laser sensor
Used this for a university project on indoor pollution. The consistency is impressive across multiple units we ordered. Highly recommended for academic or hobbyist use.

Perfect for Arduino projects
Connected easily to my ESP32. The library support is good, and the data stream is clean. It's small enough to fit into compact enclosures without issues.
Q: Is there a library available for Raspberry Pi?
A: While we do not provide an official library, many users have successfully implemented Python scripts using the standard serial GPIO pins on Raspberry Pi.
Q: Does this module output data via I2C?
A: No, this specific model outputs data via UART (TTL) and PWM. It does not support I2C communication.
Q: What is the warm-up time required before accurate readings?
A: We recommend a warm-up period of about 30 seconds to 1 minute after powering on to ensure the laser and fan stabilize for precise measurements.
Q: Can this detect cigarette smoke effectively?
A: Yes, the laser scattering principle allows it to detect fine particulate matter found in smoke, typically showing a rapid increase in PM2.5 readings.
Q: How often does the sensor need calibration?
A: The sensor comes factory calibrated. Under normal operating conditions, it maintains accuracy for years without manual recalibration.
