Passing analog signals through usb

I dont have a serial port in my laptop. So i have to use the usb for
recieving the analog outputs from the sensors for simulation. Help me in
interfacing them. There are three different analog inputs all in mVolt range.

Hi harsha,

Try Googling for serial to usb adapters. There are plenty on the market and,
as I don't know what exactly you need it for, you will have to check the
results that Google gives you for yourself.

I m doing a project in which i have to display 3 sensor outpus in a graphical
form or even a digital readout.. so i have to take these signals to my
computer.
I'll get the serial to usb adapters from the market. but how to pass the
signals through it
thankyou.

It sounds like more then serial to USB conversion. First a conversion is
needed from low level millivolt analog to a digital representation, then
convert this digital.

Lincoln actually got it right but was way ahead of his time when he said,

it?

Just a thought, you need to look at some instrumentation companies such as
NLS for some meters that can read mV levels and have an output that can be
read by computer. HPIB, HPIL, parallel, USB, etc. What kind of budget do
you have?

a max of $70-100

Nahhh, he doesn't need overpriced lab stuff.

He needs this:

I agree. Looks like he should be able to build something out of these.

how abt rs232 and an usb adapter? I have to show live changes in the sensor
outputs, which software do u suggest?

Too much trouble. Use the Phidgets stuff. They
have programming examples and API's on the page
I mentioned earlier.

I have scratch-built both serial and parallel real-world
controllers in the past, and I would never go back to
that - the newer stuff is so much easier to use and works
cross-platform.
