Indoor Air Quality Monitor

An indoor air quality monitor has a housing with air intake (24, Figure 2), a flow path leading to an air outlet (28, Figure 2) and a flow chamber (70) in the flow path; a fan to propel air through the flow path; at least one air pollutant sensor (56, 58, 60, 62) in the flow chamber; and an air guid...

Summary:An indoor air quality monitor has a housing with air intake (24, Figure 2), a flow path leading to an air outlet (28, Figure 2) and a flow chamber (70) in the flow path; a fan to propel air through the flow path; at least one air pollutant sensor (56, 58, 60, 62) in the flow chamber; and an air guide arrangement (46, 48, 64, 66, 74) in the flow path which forms a plurality of flow passages (76, 78, 80) through each of which air passes to reach the flow chamber (70). The flow passages provide a laminar flow of air to the sensors. The sensors are mounted on a carrier board which is removable from the housing. The housing interior is divided into a first air zone including the flow chamber and sensors, and second air zone isolated from the flow path. The monitor includes illuminable side panels to indicate monitored air quality.
