Description
LM35 Precision Temperature Sensor
The LM35 is a high-accuracy analog temperature sensor designed to
measure temperature in degrees Celsius. Unlike thermistors, the LM35 does not
require external calibration and provides a linear output voltage directly
proportional to the measured temperature.
This sensor operates over a wide temperature range and offers excellent accuracy
with very low self-heating. Its simple 3-pin interface makes it easy to connect
with microcontrollers such as Arduino, ESP8266, ESP32, and Raspberry Pi.
