About LM35 Temperature Sensor
The LM35 Precision Centigrade Temperature Sensor is a low-cost, linear, and precise temperature measuring IC. It provides an analog output voltage that is linearly proportional to the Celsius (Centigrade) temperature, featuring a scale factor of 10mV/°C. This sensor is calibrated directly in Celsius, eliminating the need for complex calculations. Key features include a wide operating voltage range from 4V to 30V, low self-heating, and a rated temperature range of -55°C to 150°C. It is suitable for remote applications, battery-operated devices, and general-purpose temperature monitoring in consumer electronics, industrial systems, and hobbyist projects like Arduino. Choose the LM35 for its proven reliability, ease of use with microcontrollers, and high accuracy of 0.5°C at 25°C, making it a versatile component for your temperature sensing needs.
