Ambient Weather PM2.5 Wireless Outdoor Particulate Monitor

Monitor air quality anywhere in and around your home with Ambient Weather’s PM2.5 wireless particulate monitor. The high quality sensor uses laser scattering to radiate suspending particles in the air, then collects scattering light to obtain the curve of scattering light change with time. The microprocessor calculates equivalent particle diameter and the number of particles with different diameter per unit volume. PM2.5 refers to particles that are 2.5 microns or smaller in diameter.

Includes mounting screws, a solar collector, and rechargeable batteries. A USB port allows you to charge the batteries where there is no sunlight.

Notes & Limitations:

Place the sensor in a shaded, well ventilated, non-moisture condensing area. Although the sensor is designed for outdoor use, it is best to mount in a well protected area, such as under an patio or carport.

The solar panel is sensitive to low light, but will still require monthly charging from the USB power port.

With PM2.5 sensors, fog reflects the light, and can result in a higher reading. This is characteristic to the inherent sensor design. The condition occurs during rainy or foggy weather, where Outdoor Temperature – Dew point Temperature ≤ 2ş C (3.6 şF). Thus, when the air is nearly saturated, the data is invalid.
