LM35 is a precision temperature sensor IC. Its output voltage is linearly proportional to Celsius or Centigrade temperature. It is a linear temperature sensor calibrated in Kelvin, means the user need not do any external calibration or trimming to provide typical accuracies of ±1⁄4˚C at room temperature and ±3⁄4˚C, covers a full −55 to +150˚C temperature range.
- Voltage supply: 4 to 30V
