Function of IC LM35 and How It Works
Do you looking for the function of IC LM35 ? The works of IC LM 35 typically serves as a temperature sensor. IC LM 35 is packaged in the form of integrate circuit which prisoners rates is a function of temperature, the temperature will cause a change of IC LM 35.
Heat energy from the electrodes will cause the IC LM 35 temperature changes that subsequently alter rates prisoners, the characteristics of this sensor is linear to temperature changes means that, if the temperature changes that tend to increase the temperature of the IC will also rise, as well as if the temperature falls.
The voltage output from these sensors is ± 10 mu/0C every 10C temperature rise and the largest range of temperatures - 550C to 1150C.

Fan control temperature using sensor LM35
Basic circuit of the LM35 are made to control the fan is either used on amplifier that requires automatic cooling. Its use on power amplifier circuit above and only requires DC fan. From basic sensors based on ic and amplifier op-amp is added again to the transistor Q1 to drive the fan.
