product introduction
LM35 is produced by the National Semiconductor temperature sensor, the output voltage is linear relationship with the Celsius scale transformation formula, such as type, 0 to 0 v output, every increase 1 °, the output voltage increase 10 mv.
LM35 comes in a variety of different packaging types, as shown in the figure. At room temperature, the LM35 requires no additional calibration process can reach the accuracy of plus or minus 1/4 °.
There are two power supply modes: single power supply and positive and negative dual power supply. The positive and negative dual power supply mode can provide negative temperature measurement.
Two configurations of the static electricity – low since the heat effect in the static temperature (0.08 °), single power supply mode under 25 ° about 50 mu A static current, wide working voltage, can be in 4-20 v power supply voltage is within the scope of work is very save electricity.
And LM35D is a kind of output voltage and temperature proportional centigrade temperature sensor, the sensitivity of 10 mv / °;
Working temperature range of 0 ° to 100 °;
The working voltage is 4-30v;
Accuracy of + / – 1 °.
The maximum linear error of plus or minus 0.5 °;
The static current is 80uA.
The device such as plastic sealed triode (TO-92).
The biggest characteristic of the temperature sensor is that when it is used without peripheral components, debugging and more positive (calibration), as long as the external connection of a 1V meter head (such as pointer or digital multimeter), it becomes a thermometer.
