Temperature Sensor (LM35):

Here are some key features and specifications of the LM35 temperature sensor:

1. Temperature Range: The LM35 sensor is designed to measure temperatures in the Celsius scale. The typical temperature range for the LM35 is from -55°C to 150°C. However, extended range versions may be available.
2. Output Voltage: The LM35 produces an output voltage that is linearly proportional to the temperature. The output voltage increases by 10 mV for every degree Celsius rise in temperature. The output voltage can be expressed as: Vout = 10 mV/°C * Temperature.
3. Accuracy: The LM35 is known for its high accuracy, typically within ±0.5°C at 25°C. The accuracy can vary slightly depending on the specific model and manufacturing tolerances.
4. Power Supply: The LM35 operates on a low supply voltage, typically in the range of 4 to 30 volts. It consumes very low power, making it suitable for battery-powered applications.
5. Current Consumption: The LM35 has low current consumption, typically around 60 µA.
6. Output Type: The LM35 provides an analog output voltage, which is directly proportional to the measured temperature. This analog output can be interfaced with microcontrollers, analog-to-digital converters (ADCs), or other temperature monitoring systems.
7. Calibration: The LM35 is factory calibrated, which simplifies its usage. However, for applications where higher precision is required, additional calibration may be performed.
8. Package Type: The LM35 is available in different package types, including TO-92, TO-220, and others. The package type can affect factors like size, ease of use, and thermal characteristics.
9. Stability: The LM35 is known for its stability over time, and it does not require frequent recalibration.
10. Low Self-Heating: The sensor exhibits low self-heating, minimizing temperature measurement errors caused by internal heating.
11. Applications: The LM35 is used in a variety of applications, including temperature-controlled systems, weather stations, home automation, and electronic projects where accurate temperature measurements are essential.
12. Output Scaling: The linear scaling of 10 mV per degree Celsius simplifies the conversion of the sensor output to temperature values in electronic circuits.
13. Ease of Use: The LM35 is relatively easy to use. It requires minimal external components, making it a convenient choice for hobbyists and engineers in temperature-sensing projects.
