I am going to work on an electronic thermometer which detects ambient temperature and output to a seven segment display. Range is 0C-99C and it should be able to display upto one decimal point accuracy. eg. 12.5. I searched through net and found temperature sensor ic's readily available such as LM35,LM334 etc. I like to avoid bar graph display and LCD panel displays. Display should be very active during dark and I prefer seven segments. Any inputs are welcome. Also I prefer to avoid uC's but in my limited knowledge in electronics, I think the temperature sensing IC's can directly output voltage changes and the complicated thing is to add voltage to display functionality.
