Dienmern Laser Air Quality Sensor SB4294 — 8-in-1 particulate monitor for PM10, PM2.5, PM1.0

Dienmern Laser Air Quality Sensor SB4294 — 8-in-1 particulate monitor for PM10, PM2.5, PM1.0 is a compact optical sensor module designed to detect and report airborne particulate concentrations in real time. The module uses laser scattering technology to measure a range of particle sizes and outputs data suitable for indoor air monitoring, environmental testing, HVAC inspection and integration into DIY air quality projects. Its small form factor makes it suitable for deployment in homes, offices, workshops and embedded measurement systems.

Advantages

The sensor provides fast, real-time detection of dust and smog using reliable laser optical sensing. It delivers multi-channel particulate readings including PM10, PM2.5 and PM1.0, enabling more detailed air quality assessment than single-band sensors. The compact design simplifies installation in confined spaces or integration into custom enclosures, and low-power operation supports prolonged use in continuous monitoring applications. Data output is suitable for visualization, logging or automated control systems.

Suitable for

• Indoor air quality monitoring in homes and offices
• Environmental testing and research setups
• HVAC performance checks and ventilation diagnostics
• DIY and maker projects that require particulate concentration data

Key specifications

• Detection method: laser scattering (optical)
• Measured channels: PM10, PM2.5, PM1.0 and additional particulate size channels (8-in-1)
• Response: real-time continuous measurement
• Form factor: compact module suitable for confined spaces
• Power: low-power operation for extended monitoring (typical consumption dependent on use)
• Output: particulate concentration data suitable for logging and visualization

How to use

Install the sensor in a location representative of the air you want to monitor, avoiding direct airflow from vents or windows that could distort readings. Connect the module to a compatible host or data logger according to the manufacturer's interface specifications, provide appropriate power and start continuous measurement. Verify readings against a known reference or baseline after initial setup to ensure correct operation. Place the sensor at breathing height for indoor monitoring or mount it in an enclosure for embedded applications.

Usage recommendations

For reliable results, allow the sensor to stabilise after power-up before recording long-term data, perform periodic cleaning of the inlet area to prevent dust buildup, and compare measurements with an established reference device when calibrating for specific environments.
