TDSN7400 is a USB temperature sensor that supports K-type thermocouples. It can measure temperatures in the range of -40 to 1200°C from Windows & Linux.

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).
