TDSN60420 is a general-purpose, high-precision current sensor/ammeter. It is compatible with Windows and Linux, and can obtain real-time current values in the range of ±20A.

Features

Utilizes Texas Instruments' latest high-precision current measurement IC, INA229 (compatible with INA228).
Operates with bus power, making it usable with board PCs such as Raspberry Pi and Armadillo.
Allows control of multiple devices from a single PC. It's possible to connect dozens of units using a USB hub.
Provides simple control commands compatible with Windows/Linux, facilitating easy integration into applications.
The utility software "TD-AppKit" enables real-time graph plotting and data recording/export in CSV format (Windows only).
Ideal for applications in various fields such as industrial, agricultural, and security sectors.
Comes as a compact board module covered with resin.
Designed in Japan, with options for mass production, customization, and support.

Control Command Execution Example

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

(Retrieve current value)
> td-usb tdsn604xx get
1.2331 ← Value returned in amperes

(Repeated retrieval every 100 msec)
> td-usb tdsn604xx get --loop=100
1.2331
1.3281
1.33204
...

(Record values to a text file)
> td-usb tdsn604xx listen --loop > current.txt

To integrate with a user application, call the TD-USB command externally from a program. It can be used with Python, shell scripts, C#, and more. Refer to the TD-USB documentation for integration samples.

Additionally, the demo application "TD-AppKit" can be used for graph display (Windows only).
