Advantages and Weaknesses Sensors LM35

• Advantages:
a. Remote temperature range between -55 to +150 ° C
b. Low self-heating, at 0:08 o C
c. Operating at a voltage of 4 to 30 V
d. The circuit is not complicated
e. Does not require signal conditioning

• Deficiency:
Requires source voltage to operate

LM35 temperature sensor is a small component such as a transistor (TO-92). Very easy to use components that is capable of measuring temperatures up to 100 degrees Celsius, but it is not suitable for measuring temperature sensor is included in the liquid. With the output voltage is scaled linearly with the measured temperature, which is 10 millivolts per 1 degree Celsius, then this component is suitable for use as our experiments, or even for applications such as digital room thermometer, pasteurization machine, or a digital body thermometer.

LM35DZ is a small temperature sensor components such as transistors (TO-92). Very easy to use components that is capable of measuring temperatures up to 100 degrees Celsius. With the output voltage is scaled linearly with the measured temperature, which is 10 millivolts per 1 degree Celsius, then this component is suitable for use as a friend of our experiment, or even for applications such as digital room thermometer, pasteurization machine, or a digital body thermometer.

LM35 can be supplied with a starting voltage is 4V-30V DC with a current of 60 microampere depletion. LM IC 35 as a temperature sensor that accurately and packaged in the form of Integrated Circuit (IC), in which the output is highly linear output voltage to temperature changes. This sensor serves as a temperature pegubah of physical quantities to the amount of voltage that has a coefficient of 10 mV / ° C, which means that the rise in temperature of 1 ° C there will be an increase in the voltage of 10 mV.

As the temperature sensor PT100 or PT1000 RTD types, for example, this component should not be excited by currents exceeding 1 milliampere, if exceeded, then the sensor will experience self-heating that causes the measurement result is always higher than the actual temperature.
