The main output is the unit concentration of the mass concentration of each concentration in the unit volume: micrograms per cubic meter. The output is 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 is divided into two modes: smooth mode and fast mode.
