For outdoor particulate matters

Range upto (0-31,000 µg/m³)

PAS-OUT-01 is an optically designed industrial-grade, digital laser sensor

to measure particulate matter – dust particles. 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 the concentration of particulate matter by specific algorithms.

PM2.5 Sensor – Monitor to Measure Construction Pollution

air quality solution for construction pollution by pm2.5 sensor and live streaming camera

Prana Air provides the solution of installing a PM sensor/monitor at the construction site to measure dust pollution due to construction. As per the guidelines of Govt. of India, Delhi NCR, few instructions are given in order to curb the construction pollution and demolition activities in Delhi NCR, India. Installation of PM10, PM2.5 sensor – air quality monitor, and live streaming camera at the construction site is mandatory, and online data access is also required as announced on 1st Oct 2021.

Why Choose Prana Air Outdoor PM Sensor - PAS-OUT-01?

Sl.No. Feature  Benefits 
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 in-built closed-loop control and automated feedback mechanism  Stabilizes airflow and sends feedback to the microprocessor to keep rotations per minute constant. Optimizes the operational life of the sensor. 
6 Laser is emitted at a constant wavelength  Decreases signal to noise ratio, therefore is no attenuation at high temperatures. 
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.
