 can u plz suggest me how can i measure light intensity in terms of voltage using PSoC in PSoC creator.

   

help me out with sample code and design.

There are many methods. You can use a photo transistor, diode or resistor together with an ADC. You can use a digital light sensor, which then gets connected via I2C or SPI to the PSoC.

   

What sensor are we talking about?

First, before you start any experiences, you ought to give some thougts into

   

Range of measurements

   

Accuracy

   

Noise filtering (Flourescent lamps)

   

Handling (Buttobs, switches, range select)

   

Display (reding in the dark??? Freeze button)

   

As a hint: These are the specs of your meter, write them down, will help you to keep track

You already asked these question in another thread (http://www.cypress.com/?app=forum&id=1573&rID=55337 ) and got some answers. You need to do frequency measurement, as already explained there. Do you have any additional questions? If so, please ask them so we can answer them. Or do you expect the guys here to come up with you ready-made solution?

        Bob Marlowe: my factor for designing this depends on accuracy and visible spectrum range of frequency.
