Dust sensor module boosts pollution monitoring

Omron Electronic Components Europe has launched a dust sensor module that offers four times greater sensitivity compared with other LED dust sensors on the market.

The higher performance and greater sensitivity of the sensor will allow tighter pollution control as well as the creation of more effective air purifiers and similar systems.

The Dust Sensor is able to detect particles as small as 1 micron, less than half the size of the PM2.5 standard for fine particulate matter in the atmosphere. Higher air throughput, six times that of alternatives, provides higher responsiveness to changes in the environment.

“Controlling air pollution including emissions from vehicles as well as cigarette and other smoke is a major concern for city authorities and building managers alike,” said Gabriele Fulco, European Product Marketing Manager Sensors at Omron. “It is only possible to control what can be detected, so Omron believes it is making a major contribution to the environment and public health by launching this new, highly sensitive dust sensor.”

The sensor measures 50mm x 45mm x 20mm, giving it an overall size of 20% less than popular alternative solutions. The sensor is part of a growing range of modules for HVAC and other environmental systems that includes the D6F-PH MEMS pressure sensor and the velocity sensors D6F-V which incorporate a Dust segregation System (DSS). The design of all the sensors guarantees very sensitive and temperature compensated measurement of air for a precise HVAC control.
