The LM35 is a precision temperature sensor that outputs a voltage linearly proportional to temperature in degrees Celsius, making it easy to use in temperature monitoring projects. Each 10 mV increase in output corresponds to 1°C, simplifying voltage-to-temperature conversion without additional calibration. It operates with voltages from 4 to 30 V and measures temperatures from -55°C to 150°C.
