The ams iAQ-core Indoor Air Quality Module is a low-cost, ultracompact solution for detecting poor air quality. It is equipped with an MOS sensor element for the detection of a broad range of reducing gases such as CO and VOCs. A change of resistance in the presence of these gases generates a signal that is translated into parts per million (ppm) CO2 equivalent or parts per billion (ppb) TVOC equivalent units. When defined threshold limits are exceeded, the module signals the system to initiate activities such as increasing ventilation, releasing fragrance, providing a message to open a window, switching on an air cleaner, etc. When VOC levels are minimized, the module instructs the system to return to standby, thereby saving energy, lowering operating costs and maintaining a healthy environment.
