01 — About

What it does

The LM35 Temperature Sensor is a precision integrated-circuit temperature sensor with an output voltage linearly proportional to Celsius temperature. It requires no external calibration and provides accurate temperature readings for monitoring and control applications.

Key features

  • Linear +10mV/°C scale factor for easy temperature calculation
  • Rated for full -55°C to +150°C range
  • 0.5°C accuracy at room temperature
  • Low self-heating for accurate readings
  • Low impedance output for easy interfacing
  • 4V to 30V operating voltage
  • No external calibration required

Good to know

  • Output is analog voltage – requires ADC pin on microcontroller
  • For temperatures below 0°C, negative voltage handling needed
  • TO-92 package is fragile – avoid bending leads excessively
  • Thermal mass is low – responds quickly to air temperature changes
  • Multiple LM35s can share one ADC via multiplexer if pins limited
