Temperature Sensor LM35

IC LM 35 as a temperature sensor that accurately and packed in the form of integrated circuit (IC), where the output voltage very linear output corresponding to temperature changes. These sensors serve as pegubah of physical quantities to the temperature scale that has a voltage coefficient of 10 mV / ° C which means that the temperature rise 1 ° C, there will be increased by 10 mV voltage.

IC LM 35 does not require calibration or adjustment from the outside because the accuracy to approximately a quarter degree Celsius at room temperature. Term sensors ranging from - 55 ° C to 150 ° C, IC LM35 is very easy to use, functioned as the control of the indicator display split power supply. IC LM 35 to 60 m A current flowing from supplay so that heat generated itself is very low less than 0 ° C in room temperature.

The features of the IC LM 35 is:
  • Calibration in units of degrees Celsius.
  • Lineritas +10 mV / º C.
  • Accuracy 0.5 º C at room temperature.
  • Range +2 ° C - 150 º C.
  • Operated on the power supply 4 V - 30 V.
  • The current that flows less than 60 μA
