Honeywell IPM Intelligent Particulate Matter Sensors

Posted on 16 May, 202316 May, 2023 by mixos

Honeywell IPM Intelligent Particulate Matter Sensors are laser-based sensors that detect and measure particle concentration using light scattering for monitoring air quality. The detection concentration range for Honeywell IPM is 0µg/m³ to 1000µg/m³. A laser light source illuminates a particle as it is pulled through the detection chamber. As particles pass through the laser beam, the light reflects off the particles and is recorded on the photo or light detector. The sensor then analyzes the light and converts it to an electrical signal to calculate particle concentration. During the production calibration, the sensor records the original laser light-intensity parameters and fan speed. The calibration algorithm is applied to the sensor output to minimize drift and improve the sensor’s lifetime accuracy. This self-calibration occurs on each power-on cycle.

Features

Laser-based (class 1) particle light scattering particle sensing
0µg/m³ to 1000µg/m³ concentration range
Detects 0.3µm to 10µm particles
Up to 8 years life with continuous operation
Factory calibrated
RoHS and REACH compliant

Applications

Air-quality monitors (indoors and outdoors)
Air purifiers (commercial and residential)
Automotive cabin air purifiers
HVAC (commercial and residential)
