2010 latest Analogue Temperature Sensor is based on the LM35 temperature sensor by NS (National Semiconductor Corporation), it is with high precision and wide linear working range, the output voltage is proportional to temperature, when the temperature increase 1Celsius degree, output voltage increase 10mV. It is commonly used as a temperature measurement sensors. It includes thermocouples, platinum resistance, thermal resistance and temperature semiconductor chips, which commonly used in high temperature measurement thermocouples. Platinum resistance temperature used in the measurement of 800 Celsius degree, while the thermal resistance and semiconductor temperature sensor suitable for measuring the temperature of 100-200 degrees or below, LM35 has more advantages compared with other temperature sensors with the standard of Kelvin. Without external calibration or tuning, LM35 can provide ±1/4 Celsius degree common room temperature precision. Connected with Arduino sensor Shield V5.0 , Arduino MEGA sensor Shield V1.0, SCM developing board, robot controller, it can achieve the ambient temperature detection easily.
