Omron B5W LD0101 Air Quality Sensor 

Omron’s B5W-LD0101 is a high precision air quality sensor that can detect particles as small as 0.5 µm, for more accurate sensing of the 2.5µm standard for fine inhalable particles. The sensor uses a unique flow path structure and integrated heater that efficiently generates stable airflow through the sensor, up to six times the airflow of competitors, providing consistent, accurate results. Particles scatter light between an LED and photodetector, and the sensor uses two integrated signal processing units, each for a pulse output, one is to indicate detected particles larger than 0.5 µm and another for particles larger than 2.5 µm. The sensor features a slim optical design and a compact package to simplify installation and is ideal for use in air purifiers, air conditioners, and HVAC systems.

  • Able to detect particles down to 0.5 µm
  • Greater airflow intake for consistent, accurate results
  • Light scattering detection using integrated LED and photodetector
  • Pulse output with integrated 3 kΩ pull-up resistors
  • Separate outputs for particles >0.5 µm and >2.5 µm
  • 52.3 mm (W) × 39.3 mm (H) × 17.6 mm (D) package size
