Omron launches sensitive Air Quality Sensor for pollution control and monitoring

Omron Electronic Components Europe has launched a new Air Quality Sensor module, offering four times greater sensitivity compared with other LED based 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 new B5W-LD0101-1/2 Dust Sensor from Omron is able to detect particles as small as 0.5 microns, this is less than half the size of the PM2.5 standard for fine particulate matter in the atmosphere. The sensor also features a high air throughput, of around 6 times that of established alternatives, giving improved sensitivity of response to changes in the environment.

Commenting, Gabriele Fulco, European Product Marketing Manager Sensors, Omron said “Controlling air pollution including emissions from vehicles as well as cigarettes and other smoke is a major concern for city authorities and building managers alike. 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 dust sensor uses a light scattering sensing method with a pulsed output, a 5V output pulse is produced when particles are detected, the number of output pulses is proportional to the number of particles detected allowing dust concentration [μg/m3] to be calculated within the system.

The new B5W-LD0101-1/2 dust sensor is highly compact measuring just 52.3mm x 39.3mm x 17.6mm – giving it an overall size of 20% less than popular alternative solutions, in addition the sensor is lightweight at only 20 gm making it suitable for use in portable monitoring devices.

Key Features

  • Detection of particles down to 0.5 μm in diameter is possible while using an LED light source
  • Features a unique flow path structure that efficiently sucks in air
  • Small in size due to a compact optical system
  • Supply Voltage: 5V
  • Pulsed output
  • Operating Temperature range: 0°C to 45°C

The dust sensor is part of a growing range of Omron solutions for Building Automation, Security, HVAC and other environmental systems which includes pressure sensors and velocity sensors that incorporate a Dust segregation System (DSS).
