Particle Sensor Unit

IAQ (indoor air quality) at a glance! Particle sensor to detect air-bourne particles in a room. It is sensitive to dust, particles and cigarette smoke which can trigger many allergic symptoms.

Item

PPD71 (Particle Sensor Unit)

PPD71 Particle Sensor Unit 【NEW】

Based on the light scattering method, it detects airborne particles over 0.5μm (approx.), then outputs the detection result in UART digital output based on mass concentration (μg/㎥).

PPD42NJ (Particle Sensor Unit)

PPD42NJ Particle Sensor Unit

Based on the light scattering method, it always detects airborne particles over 1.0µm(approx). Pulse output that corresponds to concentration per unit volume of particles can be obtained, with using an original detection method based on light scattered principle similar to the particle counter.

PPD20V Particle Sensor Unit

Based on the light scattering method, it detects particles over 1.0µm(approx). An analog voltage signal that corresponds to concentration per unit volume of particles can be obtained, with using an original detection method based on light scattered principle similar to the particle counter.

PPD 60PV (Particle Sensor Unit)

PPD60PV-T2 Particle Sensor Unit

Based on the light scattering method, same as particle counters, it detects air borne particles over 0.5µm(approx.), at cleanliness class from 100,000 to 1,000,000.

  • Summary
  • How It Works

PPD71, PPD42NJ and PPD20V can detect dust in your house and automatically control air-purifiers and air-quality monitors by installing the sensor in your products. PPD60PV can detect particles cleanliness class from 100,000 to 1,000,000, it can be installed in Fan Filter Units and Clean Systems to manage cleanliness of the operation line. By consulting your expected usage, we can recommend a particle sensor that best suits your needs.

Application : Air Purifier, Air Quality Monitor.

Heater (resistor) generating updraft. Infrared light beam from LED has been focused with Lens to sensing point at the center.
Airborne particles have been taken into the sensor box with the updraft.
Particle passing through sensing point scatters light, and receptor receive scattered light through the lens and transformed into pulse signal. Pulse per unit time is proportional to the particle concentration. Pulse signal are to be converted into voltage output. (PPD20V)
