Abstract
The invention provides an indoor air quality monitor (10) which has: a housing (12) providing an air intake (24) leading via a flow path, which is formed within the housing and which comprises a flow chamber (70), to an air outlet (28); a fan arranged to propel air from the air intake (24) through the flow path to the air outlet (28); at least one sensor (56, 58, 60, 62) which is for sensing at least one air pollutant, the sensor (56, 58, 60, 62) being exposed to air in the flow chamber (70); and an air guide arrangement (46, 48, 64, 66, 74) which is downstream of the air intake (24) in the flow path and which forms a plurality of flow passages (76, 78, 80) through each of which air passes in operation of the indoor air quality monitor to reach the flow chamber (70).
Claims11
An indoor air quality monitor comprising:
- a housing including a housing panel and an air guide arrangement, the housing provides an air intake leading via a flow path, which is formed within the housing and which comprises a flow chamber, to an air outlet;
- a fan arranged to propel air from the air intake through the flow path to the air outlet;
- at least one sensor which is for sensing at least one air pollutant, the sensor being exposed to air in the flow chamber;
- and
- the air guide arrangement which is downstream of the air intake in the flow path and which divides the flow path into a plurality of flow passages each of which opens into the flow chamber, so that air flow into the flow chamber is divided between the flow passages, wherein the sensor is disposed on a circuit board, and the flow chamber is defined between:
- the circuit board;
- the housing panel;
- and
- a pair of peripheral air guides extending between the circuit board and the housing panel.

- the circuit board;
- the housing panel;
- and
- a pair of peripheral air guides extending between the circuit board and the housing panel, and
- wherein the flow passages include two peripheral passages on either side of a central passage, and the central passage having a cross-sectional area at the downstream end larger than the individual cross-sectional area of each of the peripheral passages at their downstream ends.
