The LM35 Temperature Sensor for Thermal Indication is a precision integrated-circuit sensor designed to measure temperature and provide a linear analog output directly proportional to degrees Celsius. It delivers an output of 10mV per °C, enabling simple and accurate temperature monitoring without requiring external calibration. With typical accuracy of ±0.5°C at room temperature, the LM35 is ideal for thermal indication systems, temperature monitoring circuits, industrial controls, HVAC systems, battery temperature sensing, and DIY electronics projects. The sensor operates over a wide temperature range and features low self-heating, ensuring reliable and stable performance during continuous use. Its simple 3-pin configuration makes it easy to interface with microcontrollers such as Arduino and other embedded systems with analog input capability.
