The Honeywell HPM Series Particulate Matter Sensor is a laser-based sensor which detects and counts particles using light scattering. The detection concentration range is 0 µg/m3 to 1,000 µg/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 light is then analyzed and converted to an electrical signal to calculate particle concentration. The Honeywell particle sensor provides information on the particle concentration for given particle concentration range.

Frequently Asked Questions

What is the HPM Series designed to do?

The HPM Series is designed to detect airborne particulates in the PM2.5, PM10 ranges (standard) and in the PM1.0, PM2.5, PM4.0, PM10 ranges (compact). When integrated into a variety of systems, the HPM Series can help alert occupants to the presence of airborne particulates and trigger supporting equipment to improve indoor air quality. For details about the HPM Series, download the HPM datasheet or the complete list of FAQs.

What size particles does the HPM Series detect?

The HPM Series can detect particulates from 0.3 µm to 5 µm in size. The sensor uses the particle count data to provide a PM2.5 reading and calculated PM1.0, PM4.0, and PM10 readings.

What particle distributions are the HPM Series calibrated against?

The HPM Series is calibrated to cigarette smoke, which most closely correlates to burnt fossil fuels or smog. The sensor can be calibrated to other particle distributions upon request.

Where can the HPM Series be integrated?

The HPM Series features a compact design, allowing it to be seamlessly integrated into a variety of applications such as traditional HVAC controls, indoor air monitors, air purification equipment, automotive cabin filtration, and commercial kitchen ventilation.

How accurate is the HPM Series?

Engineered for excellent accuracy, the HPM Series is able to detect particulate densities to within ±15% accuracy (PM2.5). Some competitive devices offer accuracy of ±30% or worse.

How fast does the HPM Series analyze media and respond?

Ultra-fast, the HPM Series analyzes media in less than six seconds. This speed allows the HPM Series to quickly analyze and provide data to supporting equipment, allowing the device to respond to changing conditions in real-time.
