Thermometer LM35
This Thermometer used LM35 precision centigrade temperature sensor from National Semiconductors which has an analog output voltage. It has a range of -55ยบC to +150ยบC and a accuracy of ยฑ0.5ยบC . The output voltage is 10mV/ยบC . 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 0ยบC to 40ยบC and a resolution of 0.5ยบC. If you want to have a readout in Fahrenheit you can use the LM34.
