OVERVIEW
Particulates matter, monitor them
Monnit’s Wireless – PM2.5 um Meter measures PM1, PM2.5 and PM10 concentrations in the air and transmits the measurement to iMonnit. Elevated levels of PM10 (2.5-10 um) particle pollution irritate the respiratory tract and eyes; smaller PM2.5 (1.0-2.5 um) particles can penetrate deep into the lungs. As the most dangerous of all, PM1 (0.3-1.0 um) can slip through the lungs and penetrate organs.
The PM2.5 meter works by turning on a small fan at the beginning of a measurement cycle to bring in a volume of ambient air and measuring the particulate matter (PM) content of that sample volume. The sensor measures PM content using a laser that scatters based on the number and size of particles suspended in the air. It is important to keep the inlet ports of the sensor clear to ensure proper readings.
This sensor comes standard with two replaceable AA batteries. The typical battery life is approximately 10 years.

2 At temperatures above 100°C, it is possible for the board circuitry to lose programmed memory.
3 Response time may vary with stability threshold setting and PM concentration. Increasing the stability threshold will improve response time but reduce stability and accuracy of readings. With higher PM concentrations the sensor will acquire stable readings more quickly
