Simple Temperature Sensor Circuit Using Lm35 Ic 42 о Working explanation. lm35 is an application of a digital thermometer and it also measures the temperature. it is a very famous and inexpensive temperature sensor. its output varies according to the temperature around it. the range of the lm35 ic lies between 55 degrees to 150 degrees. if the temperature is 0 degrees the output will also be 0v. Switch on the 12v dc to the circuit. push and release the sw1 switch momentarily. this should instantly cause the circuit and the relay to switch on and get latched. both the leds must illuminate. next, using a soldering iron heat the lm35 to the desired level.
