Can i have any project on LM35 + PSOC4 ? for my reference.
As i am working on one project right now in which i have to interface PSOC4 with LM35 and based on temperature out from LM35 i have to send commands on UART to master controller.
You mainly need an UART and an ADC, for both of them are examples available (right click on the component).
Putting both together will be the work you need to do, remember you need 5V supply, maybe you need a level shifter (MAX232 or eq.) for UART signals.
On start page is a link to "Find Example Projects", in that is an example using
A/D. Same for UART. You can draw on these to make up your project.

I suggest to use digital thermometer DS18B20 from MAXIM instead of analog TM35. It has same formfactor, but better absolute accuracy (0.1C v. 0.5C for TM35), and its output is already digitized. Example project and component can be downloaded here.
For a proof-of-concept or a functioning prototype the price might be negligible (depending on the re$our$es available). Of interest might be the time to program the system, but here PSoCs are fastes (as I experience).
All this premises will change with the number of devices planned to be fabricated. A Sensor which needs an ADC to be red will always be cheaper than one which already has this part integrated together with a communication interface. Since a PSoC comes to us with the needed hardware inside (remarkable: at the price of the more complex sensor!!!) I (personally) would tend to choose the version which uses the cheaper and simpler sensor.

That's wholly dependent on process geometry being used and marketing plans. End of life
components, usually less integrated, older geometries, often carry higher prices. Price a 29466
out vs the equivalent in a PSOC 3 / 5LP.....
