CL-200 Series User Manual Version 1.2.0 Apr. 2019 - 5 -
1. Introduction
The CL-200 series of data logger devices can be used to record PM2.5, CO, CO2, H2S,
NH3, HCHO, TVOC, temperature, humidity and dew point information, including the
date and time stamps, and are able to store up to 450,000 downloadable records.
Real-time data can be accessed from the CL-200 data logger from anywhere and at any
time using the free Windows software, the iOSApp, or the Android App, as long as they
are connected to the same local network as the data logger.
The CL-200 series module contains RS-485, Ethernet and PoE communication
interfaces, the most common communication interfaces in industrial network. With
additional Wi-Fi interface, the CL-200-WF series provides a WLAN connection which
makes an easy way to incorporate wireless connectivity into monitoring and control
systems.

CL-200 Series User Manual Version 1.2.0 Apr. 2019 - 7 -
Features
NDIR Sensor
NDIR (Non-Dispersion Infrared) is based on one of the natural properties of CO2
molecules: CO2molecules absorb light at a specific wavelength of 4.26 µm. This
wavelength is in the infrared (IR) range. High concentrations of CO2molecules
absorb more light than low concentrations. NDIR sensor can detect fast and
accurately in a wide range of CO2concentration.
Built-in Web Server
With the built-in Web server, users can easily log in to the CL-200 module via a
standard web browser to monitor the data and configure the settings without install
any software in the terminal. Please note that the web server is only available to the
Ethernet interface.
Get Real-time Data Anywhere and Anytime
iAir App for iOS or Android Phones or Tablets is free and easy to install, it can
obtain the real-time data from CL-200 modules over a Wi-Fi network anytime and
anywhere. The iAir App can link to the CL-200 modules by specifying IP addresses
or by searching all the modules connected to the same Ethernet segment.
Data Logging Software
The DL-300 Utility can be used to configure the modules, monitor real-time data
and show the run chart, log alarm events, group CL-200 modules so that the status
of distribution groups can be
viewed and managed. The
utility also allows the log data
to be downloaded and
exported to a .CSV file that
can then be imported into
any industry-standard
software or spread sheet for
analysis.

CL-200 Series User Manual Version 1.2.0 Apr. 2019 - 8 -
Easy integration with SCADA software
Modbus is one of the most popular protocols used in the industrial world.
Supporting traditional serial protocols of RS-485 and Ethernet protocols allow the
CL-200 series well-integrated into the HMI/SCADA systems.
Alarm
CL-200 series allows users to set high alarm level for PM2.5/CO/CO2/H2S/NH3/
HCHO/TVOC/Temperature/Humidity/Dew Point and low alarm level for
Temperature /Humidity /Dew Point, and to enable/disable the alarm functions. An
Alarm LED indicator on the front of the CL-200 module will flash when an alarm
event is activated, and a relay output related to all alarm events can be use to tap
an alarm light/sound or control the IAQ devices such as ventilators, air cleaners,
and filters. Beep alarm is available when the CO/CO2/H2S/NH3/ HCHO/TVOC high
level alarm occurs.
Automatic Baseline Correction
The built-in ABC algorithm makes the CO2sensor on the CL-202, CL-212, CL-203,
CL-213, maintenance-free. In most indoor applications, the carbon dioxide level
drops to nearly outside air - 400 ppm, and then the ABC algorithm constantly keeps
track of the lowest reading and slowly corrects it as the expected fresh air value of
400 ppm. The ABC algorithm can not apply for the places where are no periods that
the CO2concentration drops to background level such as greenhouses, hospitals,
24-hour operation factories or stories. The ABC function needs be disabled where
the spaces the CO2 concentration may be elevated at all times.
Easy Wiring
Support for RS-485, Ethernet and Power over Ethernet (PoE) interfaces for users
to choose the appropriate one to meet the field requirements.
Power over Ethernet (PoE)
The CL-200 series features true IEEE802.3af-compliant (classification, Class 1)
PoE technology that allows both power and data to be carried over a single
Ethernet cable. PoE provides a unified power system, as well as backup provisions
for critical building functions, without any additional cables, outlets or connections.
It can reduce the power supply wiring and maintenance costs, and improve system
scalability.

CL-200 Series User Manual Version 1.2.0 Apr. 2019 - 9 -
Support for MQTT protocol
Compatible with IEEE 802.11b/g/n standards
The CL-200-WF modules are complied with IEEE 802.11b/g/n standard from
2.4~2.5 GHz. It can be used to provide up to 11 Mbps for IEEE 802.11b and 54
Mbps for IEEE 802.11g to connect to your wireless LAN.
MQTT is a protocol designed for the
efficient exchange of real-time data
with sensor and mobile devices. It
runs over TCP/IP and is in widest
use on the "machine-to-machine"
(M2M) and "Internet of Things"
applications today
