The LM35’s low output impedance, a linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy.\u003cbr\u003e              The main advantage of LM35 is that it is linear i.e. 10mv\/°C which means for every degree rise in temperature the output of LM35 will rise by 10mv. So if the output of LM35 is 220mv\/0.22V the temperature will be 22°C. So if the room temperature is 32°C then the output of LM35 will be 320mv i.e. 0.32V. \u003cbr\u003e              As such no extra components required to interface LM35 to ADC as the output of LM35 is linear with 10mv\/degree scale. It can be directly interfaced to any 10 or 12 bit ADC. But if you are using an 8-bit ADC like ADC0808 or ADC0804 an amplifier section will be needed if you require to measure 1°C change.\u003cbr\u003eLM35 can also be directly connected to Arduino. The output of LM35 temperature can also be given to comparator circuit and can be used for over-temperature indication or by using a simple relay can be used as a temperature controller.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eFeatures of Original LM35 Temperature Sensor:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eCalibrated directly in Degree Celsius (Centigrade)\u003c\/li\u003e\n\u003cli\u003eLinear at 10.0 mV\/°C scale factor\u003c\/li\u003e\n\u003cli\u003e0.5°C accuracy guarantee-able (at a25°C)\u003c\/li\u003e\n\u003cli\u003eRated for full -55°C to a 150°C range\u003c\/li\u003e\n\u003cli\u003eSuitable for remote applications\u003c\/li\u003e\n\u003cli\u003eLow cost due to wafer-level trimming\u003c\/li\u003e\n\u003cli\u003eOperates from 4 to 30 volts\u003c\/li\u003e\n\u003cli\u003eLess than 60 mA current drain\u003c\/li\u003e\n\u003cli\u003eLow self-heating, 0.08°C instil an air\u003c\/li\u003e\n\u003cli\u003eNon-linearity only 0.25°C typical\u003c\/li\u003e\n\u003cli\u003eLow impedance output, 0.1Ωfor 1 mA load \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003e\u003cstrong\u003eSpecifications of Original LM35 Temperature Sensor:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eLocal sensor accuracy (Max) (+\/- C): 0.5\u003c\/li\u003e\n\u003cli\u003eOperating temperature range (C): -40 to 110,-55 to 150,0 to 100,0 to 70\u003c\/li\u003e\n\u003cli\u003eSupply voltage (Min) (V): 4\u003c\/li\u003e\n\u003cli\u003eSupply voltage (Max) (V): 30\u003c\/li\u003e\n\u003cli\u003eSupply current (Max) (uA): 14\u003c\/li\u003e\n\u003cli\u003eSensor gain (mV\/Deg C): 10\u003c\/li\u003e\n\u003cli\u003eRating: Catalog\u003c\/li\u003e\n\u003cli\u003eFeatures: UL Recognized\u003c\/li\u003e\n\u003cli\u003eInterface: Analog Output\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003e\u003cstrong\u003ePackage Includes:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e1 x Original LM35 Temperature Sensor\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003eCode for orignale LM35:\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\/\/ Define the pin where the LM35 is connected\u003cbr\u003econst int sensorPin = A0;  \/\/ Analog pin connected to LM35\u003cbr\u003efloat voltage;             \/\/ Variable to store voltage\u003cbr\u003efloat temperature;         \/\/ Variable to store temperature in Celsius\u003c\/p\u003e\n\u003cp\u003evoid setup() {\u003cbr\u003e  Serial.begin(9600); \/\/ Initialize serial communication\u003cbr\u003e}\u003c\/p\u003e\n\u003cp\u003evoid loop() {\u003cbr\u003e  \/\/ Read the analog value from the LM35\u003cbr\u003e  int sensorValue = analogRead(sensorPin);\u003c\/p\u003e\n\u003cp\u003e  \/\/ Convert the analog value to voltage\u003cbr\u003e  voltage = sensorValue * (5.0 \/ 1023.0); \/\/ Assuming a 5V system\u003c\/p\u003e\n\u003cp\u003e  \/\/ Convert voltage to temperature (LM35 gives 10mV per degree Celsius)\u003cbr\u003e  temperature = voltage * 100.0;\u003c\/p\u003e\n\u003cp\u003e  \/\/ Print the results to the Serial Monitor\u003cbr\u003e  Serial.print(\"Voltage: \");\u003cbr\u003e  Serial.print(voltage);\u003cbr\u003e  Serial.print(\" V | Temperature: \");\u003cbr\u003e  Serial.print(temperature);\u003cbr\u003e  Serial.println(\" °C\");\u003c\/p\u003e\n\u003cp\u003e  \/\/ Wait for a second before the next reading\u003cbr\u003e  delay(1000);\u003cbr\u003e}\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"aeProduct.getSubject()\" src=\"https:\/\/digilog.pk\/cdn\/shop\/files\/HTB1BKXNawn-PuJjSZFkq6A-lpXat.webp\" data-original=\"https:\/\/ae01.alicdn.com\/kf\/HTB1BKXNawn.PuJjSZFkq6A_lpXat.jpg\" loading=\"lazy\" data-files=\"HTB1BKXNawn-PuJjSZFkq6A-lpXat.webp\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Digilog Electronics","offers":[{"title":"Default Title","offer_id":43962455425089,"sku":"B536,IMP500,Th250,A","price":250.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/2805\/1777\/files\/Original_LM35_Temperature_Sensor_In_Islamabad_Pakistan_af8f2c15-acf3-44a3-bef3-70b56931b96f.jpg?v=1779560688","url":"https:\/\/stem.pk\/products\/lm35-temperature-sensor-in-pakistan","provider":"stem.pk","version":"1.0","type":"link"}
