The output
The main output is the mass and number of particulate matter in each concentration per unit volume. The unit volume of the number of particulate matter is 0.1 l, and the unit mass concentration is: microgram/cubic meter.
The output can be divided into two states: active output and passive output. After the sensor is powered on, the default state is active output, that is, the sensor actively sends serial data to the host at a time interval of 200-800ms. The higher the concentration of particulate matter in the air, the shorter the time interval, the active output can be divided into two modes:Stationary mode and quick mode, particle concentration in the air changes is small, the sensor output for a smooth mode, three times per output the same set of values, with the actual data update cycle is about 2 s, when the particle concentration in the air change is bigger, the sensor output automatically switch to a fast mode, each time has the new numerical output, the updating cycle of actual data for 200-8200 ms.
