"Air Analyzer 2" is a highly accurate temperature, humidity, and CO2 (carbon dioxide) gas concentration sensor. Operates on USB bus power. Ideal for recording on a PC or implementing into user applications.
Features
- Equipped with a high-precision CO₂ sensor module from Sensirion, ensuring stable and reliable measurements.
- Includes a controllable LED indicator to visually convey status and information to users.
- Comes with the utility software “TD-AppKit”, enabling real-time graph visualization and data logging/export in CSV format (Windows only).
- Provides simple control commands compatible with Windows and Linux, allowing easy integration into applications.
- Operates via USB bus power, making it usable with board computers such as Raspberry Pi and Armadillo.
- Multiple devices can be controlled from a single PC; dozens of units can be connected using a USB hub.
- Designed in Japan. Mass production, customization, and support services are available.
Example Applications
- Indoor environment monitoring
- CO₂ concentration monitoring in greenhouse cultivation
- Environmental sensing in plant factories
- Nursing care / monitoring systems
- Security applications (intrusion detection using CO₂ levels)
How to Use Control Commands
The device uses Tokyo Devices’ standard control command interface,“TD-USB.” When executed, the command outputs CO₂ concentration (ppm), temperature (°C), and humidity (%RH).
(Get values from the sensor)
> td-usb tdsn7300 get
653,25.4,42.2
(Get values every 60 seconds)
> td-usb tdsn7300 get --loop=60000
653,25.4,42.2
655,25.4,42.4
651,25.3,42.8
....
(Log data to a CSV file)
> td-usb tdsn7300 get --loop=60000 > log.csv
(Turn on the LED)
> td-usb tdsn7300 set 1
To integrate with user applications, call TD-USB as an external command from your program. It can be used with Python, shell scripts, C#, LabVIEW, and more. Refer to the TD-USB documentation for integration examples.
You can also visualize data using the demo application “TD-AppKit” (Windows only).
