The TDSN450 is an infrared proximity sensor that detects whether there is an object in front of the sensor. Control commands are provided for operation on Windows/Linux.
Features
- Can detect any object that reflects infrared rays (solid, liquid, human hand, etc.).
- Uses a pulse modulation method that is resistant to interference from ambient light.
- Control commands compatible with Windows/Linux are provided, making it easy to integrate into systems.
- Operates on bus power, eliminating the need for an external power source.
- Capable of a high-speed response time of a minimum of 16 milliseconds (※varies depending on the OS, example given for Windows).
How to Use
- Simply connect to a USB port to use.
- Controlled using Tokyo Devices' standard control command "TD-USB".
- A demo application "TD-AppKit" utilizing TD-USB is available (Windows only).
TD-USB Command excamples
Retrieve the current strength of infrared reflection on a scale from 0 to 1023.
> td-usb tdsn450 get
320
Set the threshold to 300±10 and write it to the device.
> td-usb tdsn450 set THRESHOLD=300
> td-usb tdsn450 set HYSTERESIS=10
> td-usb tdsn450 save
When the value exceeds the threshold, output "1"; when it falls, output "0".
