Precision Integrated Circuit Linear Centigrade LM35 Temperature Sensor With Analog Signal A Output
Introduction
Adopt with LM35 temperature sensor, output voltage is Celsius temperature scale.The basic working
principle: LM35 temperature sensor circuit converts the measured
temperature signal into a voltage signal and outputs it to the
signal amplifying circuit. The voltage signal corresponding to the
temperature value is amplified and utput to the A/D conversion
circuit, and the voltage signal is converted into a digital
quantity,sent to the single-chip system, the single-chip system
processes the digital quantity according to the display
requirements, and then sends it to the temperature display system
for display.

Application example
The LM35 Linear Temperature Sensor is based on the semiconductor
LM35 temperature sensor. The LM35 Linear Temperature Sensor can be
used to detect ambient air temperature. This sensor is produced by
National Semiconductor Corporation and offers a functional range
between -40 degree Celsius to 150 degree Celsius. Sensitivity is
10mV per degree Celsius. The output voltage is proportional to the
temperature.
It is commonly used as temperature measurement sensors. It includes
thermocouples, platinum resistance, thermal resistance and
temperature semiconductor chips,which commonly used in high
temperature measurement thermocouples. Platinum resistance
temperature used in the measurement of 800 degrees Celsius, while
the thermal resistance and semiconductor temperature sensor
suitable for measuring the temperature of 100-200 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.
The LM35 linear temperature sensor can connect with Arduino Sensor
Shield V5.0 or Arduino MEGA Sensor Shield V1.0 by 3P line
directly,it can contect with many kinds of development
boards,robotic controllers,and can detect environment temperature
around easily,it is the common sensor to make Interactive Works and
Intelligent Robot.
