An air quality monitor (10) comprising a housing (14), within which are electronic components (25) including sensors (36, 37, 38) at least for temperature, humidity, particulates, and volatile organic compounds (VOCs), though other sensors such as CO2 or light intensity may be optionally added, a processor (42) to deduce a measure of indoor air quality from the measurements from the sensors, and a fan (26) to draw ambient air into and through the housing; and also includes a means (44) for local wireless networking (Wifi RTM) communication. The particulates sensor (36) may detect particles of mean size less than 2.5 pm. The Wifi RTM means (44) may enable data about external air quality and weather to be obtained from the Internet or transmit information or suggestions for air quality improvement to a remote server or mobile device. The housing (14) may define at least one aperture (24) for inflow of air, and a bell-shaped outflow duct (18), each aperture (24) being concealed behind a baffle (15). The device may have both a mains power connection and a battery power supply allowing for portability between multiple deployment locations. The housing of the monitor is constructed to direct air-flow through the device. |
