Abstract:
In this paper, LM35 tempeture sensor is tested and shows good linear characteristics between 30 ℃ and 60 ℃, which provides a theoretical basis for making digital thermometer. A/D converting chip and 89c51 single chip micro -processor are employed in this digital body thermometer based on LM35. It possesses such advantages as low cost, high accuracy and excellent stability.
