Hello,
I am working on a project to measure ambient temperature using a small microntroller.
I originally planned to use the DS1621 temperature sensor which gives a digital equivalent of the measured temperature in as a serial output to the microcontroller. Unfortunately for me, the DS1621 is not currently available at the local store so I decided to revert to the common LM35. the problem is that LM35 gives an analog output and since i want to interface with a microntroller, I would like to have a digital equivalent of the measured temperature in the form of an 8 bit word available in parallel form.
I would want to keep the circuit as simple as possible. an would be grateful for any suggestions or ideas.
Thanks.
