B5W-LD0101-1/2 Air Quality Sensor

Highly Sensitive and Compact Air Quality Sensor

  • 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 thanks to its compact optical system
RoHS適合
