O.K. For a positive temperature measurement, connect the LM35 output to a Z8F6401 analog input. The LM35 supply has to be >= 4V. A digital I2C sensor could be used of 3V supply directly.
since LM35 is mentioned here. I would like to put up my query as well. I want to use LM35 and have a simple display of temperature. Nothing more nothing less. Just the temp in deg C or deg F will do. I do not want anything complicated. Any help will be highlyy appreciated! Thanks!
