Function: Measures ambient temperature and provides output in analog voltage or digital signal (I2C, SPI, or 1-Wire).

Common Types:

• Analog: LM35, TMP36 – Output voltage linearly proportional to temperature.
• Digital: DS18B20 (1-Wire), BMP180 (I2C), TMP102 (I2C) – Provide calibrated digital readings.

Applications: Environmental monitoring, HVAC, microcontroller-based systems.

Voltage Range: Typically 2.7V to 5.5V.

Accuracy: ±0.5°C to ±2°C depending on model.

Interface Notes:

• Analog: Connect to ADC pin of MCU.
• Digital: Use appropriate pull-up resistors (e.g., 4.7kΩ for 1-Wire/I2C).
