PM2.5 Basic parameters of indoor sensors
The indoor PM2.5 sensor/transmitter can be used in a variety of intelligent buildings and HVAC systems, such as airports, train stations, subway stations, pharmaceutical factories, museums, intelligent buildings and gymnasiums. The product adopts imported high-performance processor and high-performance PM2.5 sensor, particle counting principle, can be sensitive to detect particles larger than 1 μm in diameter.PM2.5 internal sensor/transmitter can choose current and voltage output signals, 485 output signals and 485 serial outputs, and use the standard MODBUS communication protocol. It can be widely used in indoor home environment monitoring, factory environment monitoring, office environment monitoring, atmospheric monitoring and other places.
