Schematic Rise

This is a simple Temperature Sensor Circuit Diagram. The LM35 temperature sensor provides an output of 10 mV/C for every degree Celsius over 0C. At 20C the output voltage is 20 10 = 200 mV. The schema consumes 00. The load resistance should not be less than 5 kQ. A 4- to 20-V supply can be used.
