LM35 Temp Sensor

Description

The LM35 is a precision analog temperature sensor that provides an accurate and linear output voltage directly proportional to the temperature in degrees Celsius. Here’s a description of its key features and characteristics:

**1. Temperature Sensor:** The LM35 is primarily designed to measure temperature. It converts the temperature into an analog voltage output that is linearly related to the temperature in degrees Celsius.

**2. Precision:** The LM35 is known for its high level of precision and accuracy in temperature measurement, making it a reliable choice for various applications.

**3. Linear Output:** The output voltage from the LM35 increases linearly with temperature. For every 1 degree Celsius rise in temperature, the output voltage increases by 10 mV. This linear relationship simplifies temperature measurements.

**4. Voltage Output:** The LM35 typically provides an output voltage in the range of 0 mV (at 0°C) to 1.5V (at 150°C). The output can be easily interfaced with analog-to-digital converters (ADCs) for further processing.

**5. Wide Temperature Range:** The LM35 is suitable for a wide temperature range, typically from -55°C to +150°C, making it versatile for many applications.

**6. Low Power Consumption:** It operates on low power, making it energy-efficient and suitable for battery-powered applications.

**7. Calibration:** The LM35 is pre-calibrated at the factory, so there’s no need for additional calibration in most cases.

**8. Integrated Circuit:** The LM35 is a complete temperature sensor in a TO-92 transistor-like package, which is easy to use and integrate into various electronic circuits.

**9. Versatile Applications:** It is used in a wide range of applications, including temperature monitoring and control in electronic equipment, environmental monitoring, weather stations, HVAC (heating, ventilation, and air conditioning) systems, and more.

**10. Simple Interfacing:** Interfacing the LM35 with microcontrollers or other digital circuits is straightforward since it provides a linear analog output.

**11. Inexpensive:** The LM35 is an affordable and widely available temperature sensor, making it a cost-effective choice for temperature-sensing applications.

**12. Minimal Calibration:** In most applications, minimal or no calibration is required because of its factory calibration and high accuracy.

The LM35 is a popular and reliable temperature sensor that has found use in a wide range of temperature monitoring and control applications due to its accuracy, simplicity, and linear output. It provides a straightforward way to measure temperature in electronic systems and is a versatile tool for temperature-related projects.
