Temperature Range: The LM35 is designed to measure temperatures within a specified range, typically between -55°C to +150°C. However, variations of the LM35 may have different temperature ranges.
Output Voltage: The sensor provides an output voltage that is directly proportional to the temperature being measured. The scale factor is typically 10 mV/°C, meaning that for every degree Celsius change in temperature, the output voltage changes by 10 millivolts.
Quiescent Current: The sensor has a low quiescent current, making it suitable for battery-powered applications.
Accuracy and Calibration: The LM35 is known for its high accuracy and stability over a wide temperature range. However, calibration may be necessary for certain applications to achieve precise temperature measurements.
Package Types: The LM35 is available in different package types, such as TO-92, TO-220, and SOIC, offering flexibility for various circuit designs and applications.
HVAC Systems: Integrated into heating, ventilation, and air conditioning (HVAC) systems for temperature control and monitoring.

Description
The LM35 is a precision integrated-circuit temperature sensor that provides an analog voltage output proportional to the temperature in Celsius.Here's a detailed description of the LM35 temperature sensor:
Operating Principle: The LM35 operates on the principle of a temperature-dependent voltage output. It contains a precision temperature sensor with a linear output characteristic, meaning that the output voltage changes linearly with temperature changes.Temperature Range: The LM35 is designed to measure temperatures within a specified range, typically between -55°C to +150°C. However, variations of the LM35 may have different temperature ranges.
Output Voltage: The sensor provides an output voltage that is directly proportional to the temperature being measured. The scale factor is typically 10 mV/°C, meaning that for every degree Celsius change in temperature, the output voltage changes by 10 millivolts.
Operating Conditions:
Supply Voltage: The LM35 operates at a low supply voltage, typically between 4 to 30 volts DC. A stable power supply is recommended for accurate temperature measurements.Quiescent Current: The sensor has a low quiescent current, making it suitable for battery-powered applications.
Accuracy and Calibration: The LM35 is known for its high accuracy and stability over a wide temperature range. However, calibration may be necessary for certain applications to achieve precise temperature measurements.
Package Types: The LM35 is available in different package types, such as TO-92, TO-220, and SOIC, offering flexibility for various circuit designs and applications.
