This is an Arduino Temperature Sensor based on LM35 temperature chip.
A Temperature Sensor can be used to detect ambient air temperature.
The LM35 chip is produced by National Semiconductor Corporation and offers a functional range between 0 degree Celsius to 100 degree Celsius with a sensitivity of 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.
This temperature sensor suitable for measuring the temperature of 0-200 degrees or below, in which the application of a simple semiconductor temperature sensor has good linearity and high sensitivity. The LM35 linear temperature sensor and sensor-specific expansion of Arduino board, in combination, can be very easy to achieve.
How to Use LM35 Analog Temperature Sensor Module – 4V To 20V
