LM35 Temperature Sensor

MEASUREMENT RANGE: Provides reliable temperature sensing across a wide range from −55°C to +150°C, supporting both low-temperature and high-temperature monitoring applications
SENSING PRINCIPLE: Delivers an output voltage linearly proportional to temperature in degrees Celsius with a scale factor of 10 mV/°C, enabling straightforward temperature interpretation
ACCURACY PERFORMANCE: Ensures high measurement precision with typical accuracy of ±0.25°C at room temperature and around ±0.75°C across the full operating range
POWER SPECIFICATIONS: Operates within a supply voltage range of 4V to 30V while maintaining extremely low current consumption of less than 60 µA
THERMAL CHARACTERISTICS: Designed with very low self-heating behavior, producing approximately 0.08°C temperature rise in still air during operation
INTERFACE DESIGN: Features a simple 3-pin configuration (VCC, VOUT, GND) allowing direct connection with microcontrollers, ADC inputs, and embedded monitoring systems
OUTPUT CHARACTERISTICS: Provides a low-impedance analog output (~0.1 Ω for 1 mA load), ensuring stable signal transmission even in remote sensing setups
APPLICATION SCOPE: Commonly used in environmental monitoring systems, embedded temperature measurement circuits, industrial control units, laboratory instruments, and electronic device thermal management
