The new PM2.5 duct type fine dust sensor from Siemens Smart Infrastructure comes in two variants and creates a healthy as well as productive indoor air climate. Part of the Symaro product group, the sensors measure dust and dirt particles, including fine sand, transmitting them rapidly and precisely to advanced building management systems for comprehensive climate monitoring and control. This improves the indoor air quality of residential and commercial buildings, which in turn has a positive effect on the health and comfort of room occupants. By ensuring the early detection of hazardous particles, the sensors help achieve energy and cost- efficient control of the entire HVAC system.
