Temperature Analog Sensor Module LM35D

The Arduino LM35 Linear Temperature Sensor module is based on the semiconductor LM35 temperature sensor. The LM35 Linear Temperature Sensor module can be used to detect ambient air temperature. Sensitivity is 10mV per degree Celsius. The output voltage is proportional to the temperature.It is commonly used as a temperature measurement sensors. It includes thermocouples, platinum resistance, thermal resistance and temperature semiconductor chips, which commonly used in high-temperature measurement thermocouples. The LM35 linear temperature sensor and sensor-specific expansion of Arduino board, in combination, can be very easy to achieve.
