General Purpose USB Thermocouple Temperature Sensor K type -40 to 1200℃ Galvanic Isolation Bus-Powered

Features

• Equipped with Analog Devices' latest high-precision IC, "MAX31856." The standalone sensor's maximum measurement range is -40 to 1200°C (actual range may be limited by the probe's heat tolerance).
• The measurement section and USB section are electrically isolated, providing strong resistance to noise and allowing measurements of targets with differing voltage levels.
• Operates via USB connection (bus-powered), compatible with board PCs such as Raspberry Pi and Armadillo.
• One PC can control multiple devices, with the ability to connect dozens of units using a USB hub.
• Simple control commands compatible with Windows/Linux are provided, making integration into applications easy.
• The utility software "TD-AppKit" allows real-time graph display and data recording/export in CSV format (Windows only).
• Ideal for applications in industrial, research, and security fields.
• Provided as a small board module covered with resin.
• Designed in Japan. Mass production, customization, and support are available.

How to Use Control Commands

The standard control command "TD-USB" from Tokyo Devices is used.

To retrieve temperature:    
> td-usb tdsn7400 get        
31.21348   ← Temperature (°C) is returned.

To repeatedly retrieve values every 60 seconds:
> td-usb tdsn7400 get --loop=60000
25.32831
25.23313
25.48544
...

To record the output to a text file:
> td-usb tdsn7400 listen --loop > temperature.csv

To integrate with user applications, invoke TD-USB as an external command from your program. It can be used with Python, shell scripts, C#, and others. For more details, refer to the TD-USB documentation for integration examples.

Additionally, the demo application "TD-AppKit" allows for graphical display of data (TD-AppKit is Windows only).
