The LM35 of National Semiconductors that is used in this project is a precision centigrade temperature sensor, which has an analog output voltage. It has a range of-55潞C to+150潞C and a accuracy of 卤0.5潞C . The output voltage is 10mV/潞C . The output voltage is converted by the AD convertor of the AT Mega8. The temperature is displayed on an LCD module. In this example the thermometer has a range of 0潞C to 40潞C and a resolution of 0.5潞C. If you want to have a readout in Fahrenheit you can use the LM34.
