LM35 is a popular analog temperature sensor that measures the temperature in Celsius (°C). It provides a linear output voltage that is directly proportional to the temperature, making it easy to interface with microcontrollers or other electronic systems.
Temperature Range: Typically, the LM35 can measure temperatures from -55°C to 150°C.
Output Voltage: The LM35 gives an output of 10 mV per °C. For example:
At 0°C, the output voltage is 0V.
At 25°C, the output voltage is 250 mV (25 * 10 mV).
At 100°C, the output voltage is 1V (100 * 10 mV).
Accuracy: It has a relatively high accuracy, typically within ±0.5°C.
Low Power Consumption: It operates on a voltage supply of 4V to 30V, making it ideal for battery-powered applications.
Simple to Use: The LM35 doesn’t require any external calibration or complicated circuit designs. It can easily be read with an analog-to-digital converter (ADC) on a microcontroller.
