LM35 Temperature Sensor Module

The LM35 Temperature Sensor Module is a widely used analog temperature sensor that measures temperature in Celsius and provides a voltage output that is linearly proportional to the temperature. It is commonly used in various electronic and embedded systems, such as temperature monitoring, automation, and control applications.

Key Features of LM35 Temperature Sensor Module:

1. Analog Output:

   • The LM35 sensor outputs an analog voltage that corresponds to the measured temperature. The voltage increases by 10 mV per degree Celsius. For example, at 25°C, the output would be 250 mV.

2. Operating Voltage:

   • The LM35 typically operates within a voltage range of 4V to 30V, making it suitable for use in many microcontroller systems, such as Arduino, Raspberry Pi, or other microcontroller-based projects.

3. High Accuracy:

   • The LM35 offers good accuracy, with a typical error of ±0.5°C. It can measure temperatures ranging from -55°C to +150°C, which makes it suitable for a wide variety of applications.

4. Low Power Consumption:

   • The sensor consumes very little power, typically around 60 µA (microamperes) at a supply voltage of 5V, making it ideal for low-power applications.

5. Linearity:

   • The LM35 is known for its high linearity, meaning that the output voltage is directly proportional to the temperature. This makes it easy to interpret the readings with simple scaling and conversion.

6. No Calibration Needed:

   • The LM35 does not require any complex calibration or external components to function properly, making it easy to integrate into circuits and projects.

7. Wide Operating Range:

   • The sensor is designed to operate in various environments and can handle a broad temperature range from -55°C to +150°C.

How it Works:

The LM35 temperature sensor has three pins:

• VCC (Pin 1): Power supply pin.
• VOUT (Pin 2): Analog output pin, which gives a voltage proportional to the temperature.
• GND (Pin 3): Ground pin.

The LM35 produces a voltage output where the voltage increases by 10 mV per °C of temperature increase. For example, at 0°C, the output will be 0V, at 25°C, it will be 250 mV, and at 100°C, the output will be 1000 mV (1V).
