I want to interface a IR Proximity Sensor with Personal Computer for our project. Is it okay if usb will be used? Is it possible to interface without using a microcontroller? What should I do to be able a PC detect a signal from a sensor? And by using Visual Basic 6.0, how a form will pop up once the sensor was triggered?

I've search a lot in google but still can't get the right answer. Please give me some advice regarding my problems.
Thaaaaaankssss! :smile:
 

Those are some pretty broad questions. First of all, if your IR sensor doesn't have a USB output, then you'll need some kind of sensor-to-USB converter.

If your sensor output is a logic-level, then there are inexpensive digital I/O boards available that you can install in your pc, as well as digital i/o to usb converters.

Your VB form question is a total non-sequitur. One thing at a time!! You have to figure out what your hardware is first.
