PM2.5 LASER SENSOR
For outdoor air quality monitoring devices
For outdoor particulate matters
PAS-OUT-01 is an optically designed industrial-grade, digital laser sensor
to measure particulate matter. It comes with a built-in laser and photoelectric receiving module.
Different than its contemporaries, PAS-OUT-01 is calibrated for PM10 and PM2.5 separately. It works on the principle of
90° light scattering. The light that strikes the aperture of the mirror at 90° is reflected towards the sensor.
The photodiode registers pulse for as long as the light is reflected. The electrical signal thus received is converted
into concentration of particulate matter by specific algorithms.

Designed To Be Discreet
|1||Anti-dust duct and durable components.||Lifetime of more than a decade with continuous operation of 24 hours/day. Maintenance-free, thus avoiding problems related to sensor drift or malfunction.|
|2||Laser-based scattering principle and Advanced algorithms.||Precise and reliable measurements.|
|3||Accurate high-resolution particle sizing.||Enables device-specific actions based on detected particle composition. Broadens the range of applicability pertaining to specific particle size.|
|4||Small, ultra-slim package||Easy to integrate into devices with limited size and space.|
|5||Fan with an in-built closed loop control and automated feedback mechanism||Stabilizes air flow and sends feedback to microprocessor to keep rotations per minutes constant. Optimizes operational life of the sensor.|
|6||Laser is emitted at constant wavelength||Decreases signal to noise ratio, therefore no attenuation at high temperature.|
|7||Moisture-proof design||Reduces the probability of error in optical measurements due to humidity|
|8||Fully calibrated digital output for particle number and mass concentration values. UART and I2C interfaces.||Simple interfacing and read-out of multiple outputs.|
