No external calibration or trimming is required, achieving typical accuracies of ±0.5°C at room temperature. It is widely used in Arduino, AVR, and PIC projects for reliable temperature monitoring.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e4V to 30V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Scale\u003c\/td\u003e\n\u003ctd\u003e10 mV\/°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e-55°C to 150°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±0.5°C (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eAnalog voltage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003eTO-92 (3-pin)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-digital-thermometer-on-lcd\"\u003eDigital thermometer with Arduino and a 16x2 LCD display\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-fan-temperature-controller\"\u003eAutomatic fan speed controller based on ambient temperature\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eOverheat alarm for batteries, motors, or enclosed electronics\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-cold-chain-temperature-data-logger\"\u003eTemperature data logger for greenhouse or laboratory monitoring\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThe LM35 operates from a single supply (4V–30V) and draws only 60 µA, making it compatible with any microcontroller having an analog input, such as Arduino Uno, Nano, ESP32, and Raspberry Pi Pico. It outputs a linear voltage, easily read by 10-bit or 12-bit ADCs. Often paired with 7-segment displays or serial plotters for real-time visualization.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect the VCC pin to 5V (or 3.3V for reduced self-heating), GND to ground, and the output pin directly to an analog input channel. No pull-up resistors or external components are required. For accurate readings, keep the sensor away from PCB heat sources and provide slight air circulation if measuring ambient air.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, the LM35 works directly with Arduino boards by connecting its output to an analog pin, then using analogRead(). Convert the ADC value to Celsius with: temperature = (analogValue * 5.0 \/ 1024.0) * 100.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eDoes it need external calibration?\u003c\/summary\u003e\u003cp\u003eNo, the LM35 is factory-calibrated to produce 10 mV per degree Celsius with ±0.5°C accuracy. For most hobbyist and educational projects, no recalibration is necessary.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat is the difference between LM35 and LM34?\u003c\/summary\u003e\u003cp\u003eThe LM35 outputs temperature in Celsius, while the LM34 outputs in Fahrenheit. Both are analog sensors, but the LM35 is more common for metric-based projects and easier integration with Celsius-referenced software.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
