The CL-200-WF is an IAQ (Indoor Air Quality) monitoring module that includes Wi-Fi, Ethernet and RS-485 interfaces, It provides a WLAN connection which complies with the IEEE802.11b/g/n standards. With the popularity of 802.11 network infrastructure, the modules provide an easy method of incorporating wireless connectivity into monitoring and control systems. The CL-200-WF series of Data Logger devices can be used to record PM1/PM2.5/PM10 and the number of particles (0.3μm, 0.5μm, 1μm, 2.5μm, 5μm, 10μm), CO, CO2, NH3 , H2S, HCHO, TVOC, Temperature, Real-time data can be accessed from the CL-200-WF Data Logger from anywhere and at any time using the free Windows software, the iOS App or the Android App, as long as they are connected to the same local network as the Data Logger.
 
Support is provided for popular industrial protocols such as DCON, Modbus RTU, and Modbus TCP. For Ethernet interface, it also supports the emerging machine-to-machine (M2M)/)IoT (Internet of Things) connectivity protocol – MQTT. The CL-200-WF Data Logger can be connected via widely used communication interfaces including RS-485, Ethernet, PoE and Wi-Fi, meaning that the device can be easily integrated into existing HMI or SCADA systems, and is easily maintained in a distributed control system.
 

The MQTT protocol is designed for the efficient exchange of real time data between a sensor and a mobile device. It operates via TCP/IP and is in widest use today in "machine-to-machine" (M2M) and "Internet of Things" applications.

Real-time data from the CL-200 data logger can be accessed from anywhere and at any time using the iAir Utility, the iOS or Android App, or via a regular web browser, as long as they are connected to the same local network as the data logger.

The iAir Utility is a powerful tool that is designed for configuring the modules, monitoring real-time data, grouping CL-200 modules to view and manage the status of distribution groups, downloading log data, which can be exported to a CSV fi le that can then be imported into any industry-standard software or spreadsheet for analysis.

The air quality automation system for indoor or underground parking lot can use the CL-220 series modules to monitor the health and safity information, such as PM1,PM2.5,PM10, CO, CO2, temperature, humidity, dew point, and more...
