AptObject, which specializes in the building of cloud systems and data analysis, has discovered the advantages of ZigBee's mesh capability in 2006. Since then, the company has developed its own 2.4G wireless module and ZigBee-based energy and security management system optimized for applications in homes, parking lots and factories. In the smart home field, AptObject's system has been deployed mainly via services introduced by security companies.
The whole package of AptObject's cloud services comprises of three subsystems: interior air quality monitoring, security and surveillance, and energy management. The mostly required air-quality system includes CO, CO2, temperature and humidity detectors, and siren alarm. In the near future, CH2O detector will be added.
“We choose ZigBee as the main wireless protocol in our system because of its multi-hop feature,” explains Andy Chang, Firmware Engineer of AptObject Corporation. The ZigBee network structure is simplified and adaptive, which makes it ideal in the controlling of switches and sensors.
“The data gathered by sensors can be sent to the cloud and then analyzed to create many valuable applications,” says Chang. Via APTObject 's management software (APP versions are also available), users are allowed to deploy and rename these end devices on a visualized interface. They can also monitor environmental status or review historical data records.
Furthermore, users are able to create automated interactions between sensors and appliances under specific circumstances. For instance, an electric fan can be activated when the concentration of CO2 in the atmosphere reaches certain value which can be preset by users themselves.
