The Monnit ALTA wireless Air Quality PM2.5 um meter measures PM1, PM2.5 and PM10 concentrations in the air and transmits the measurement to iMonnit. 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 readingsImportant Note: Monnit Alta wireless sensors must be paired with a Monnit Alta gateway in order to have a working system. One Serial Modbus gateway can support up to 50 sensors and one Ethernet, USB, or Cellular gateway can support up to 100 sensors. Monnit Alta gateways can be found on the accessory tab.
