Digital Thermometer using PIC Microcontroller and LM35 Temperature Sensor

Basics A Digital Thermometer can be easily constructed using a PIC Microcontroller and LM35 Temperature Sensor. LM35 series is a low cost and precision Integrated Circuit Temperature Sensor whose output voltage is proportional to Centigrade temperature scale. Thus LM35 has an advantage over other temperature sensors calibrated in Kelvin as the users don’t require subtraction of large constant voltage to obtain the required Centigrade temperature. It doesn’t requires any external calibration. It is produced by National Semiconductor and can operate over a -55 °C to 150 [...]
