ELECFREAKS PlanetX PM2.5 Sensor STEAM kits and other 12V LED devicesPM2. 5 is the particulates in the air with a diameter less than or equal to 2. 5 microns. It usually carries heavy metals and microorganisms, and it stays in the air for a long time, which has a great impact on human health and the quality of the atmosphere. The PM2. 5 sensor is able to detect the concentration of particulates in the air around us, observe the weather, and create an experimental environment. Specifications Connections: RJ11 4P4C
