Particulate Matter Sensor Provides Reliable Operation and Long Life in Indoor Air-Quality Monitoring Systems
In response to increasing concern worldwide over indoor air quality, Panasonic has introduced the SN-GCJA5, a particulate matter sensor which uses an innovative optical sensor assembly to provide reliable operation and a long lifetime while accurately detecting particles as small as 0.3µm.
A complete, intelligent sensor module, the SN-GCJA5 provides calibrated readings of the concentration of PM10, PM2.5 and PM1.0 particles, which have a diameter of 10µm, 2.5µm and 1µm.
The sensor’s air pathway minimizes the distance from the intake to the exhaust, and isolates the flow of gas from the module’s control electronics, to avoid the risk that particulate matter will contaminate the system.
The SN-GCJA5 may be used to provide comprehensive indoor air-quality measurements for regulating the operation of systems such as air-conditioning units, air purifiers and automated building ventilation systems. It is sensitive to a wide range of airborne contaminants including dust, ash, soot, smoke, aerosols, fumes, mist, condensing vapor and bacteria.
The operation of the SN-GCJA5 is demonstrated in a new application development board designed by Future Electronics in collaboration with Panasonic. The FPA-PMGE1780 board is based on the SN-GCJA5 particulate matter sensor. It is mounted on a system board with:
- The PAN1780 Bluetooth® Low Energy radio module, which provides a ready-made wireless connection to a host device such as a smartphone or laptop computer
- The AMG88, a GridEYE thermal array sensor, which can be used to detect the presence of people, and for ambient temperature measurement
The FPA-PMGE1780 board therefore provides a ready-made demonstration of a connected indoor air-quality sensor system, helping accelerate the development of new concepts in smart home automation and smart building control.
