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.
