Dimensions

TDFA60250 is a USB voltage meter that supports 0-5V and 1-5V analog signals. It can provide real-time data acquisition at a speed of up to 1,000 samples per second with a resolution of 12 bits (4,096 levels).

Features

It operates on bus power, making it compatible with single-board computers like Raspberry Pi.
Electrical isolation between USB/PC side and measurement side circuits prevents noise interference and limits the impact of accidents.
Free control commands "TD-USB" that work on Windows/Linux are provided, making it easy to integrate into custom applications.
Calibration is possible using control commands.
You can visualize data using the demo application "TD-AppKit" (TD-AppKit is only available for Windows).

How to Use

Use Tokyo Devices' standard control command "TD-USB".

(Get the current value once, unit: V)
% td-usb tdfa60250 get
3.42311

(Continuously get the current value, 1,000 samples per second)
% td-usb tdfa60250 listen --loop
3.42311
3.5392
3.5392
...

(Record to a text file)
% td-usb tdfa60250 listen --loop > output.txt

To integrate it with your custom application, call TD-USB as an external command. It can be used from Python, shell scripts, C#, and more. Refer to the integration samples in the TD-USB documentation.
