General purpose, Load cell to USB interface, Weight/Pressure sensor, 24-bit, Bus-power

• Operates via USB connection (bus-powered). Can also be used with board PCs 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.
• Simple control commands compatible with Windows and Linux are provided, making integration into applications easy.
• The utility software “TD-AppKit” enables real-time graph display and data logging/output in CSV format (Windows only).
• Ideal for applications in industrial, research, security, and other fields.
• Designed domestically. Mass production, customization, and support services are available.

How to Use Control Commands

Use the Tokyo Devices standard control command “TD-USB.”

(Get a value)
> td-usb tdsn7502 get
133   (← weight is returned in grams)

(Get values continuously every 3 seconds)
> td-usb tdsn7502 get --loop=3000
100
102
105

(Log values to a CSV file every 3 seconds)
> td-usb tdsn7502 get --loop=3000 > log.csv

To integrate with a user application, call TD-USB as an external command from your program. It can be used from Python, shell scripts, C#, LabVIEW, and other environments. For details, refer to the datasheet and the integration examples in the TD-USB documentation.

Graph display is also available by using the demo application “TD-AppKit” (Windows only).
