ESTE: Analog Temperature Sensor 1 (LM35DT - Precision Centigrade Temperature Sensors)
This experiment is part of this project.
Here we are going to build one experiment to use the ADC and to learn how to use a temperature sensor. Among many types of temperature sensors we are going to use the LM35DT, a precision integrate-circuit temperature sensor, that is directly calibrated in °Celsius (Centigrade) with an output voltage linear (10 mV/°C). So if we want to use this sensor to measure the temperature of one enviroment in °C we will just need to convert each 10mV to 1°C. If we also want to measure the temperature in °F we will need to convert the obtained temperature in °C to °F through the equation °F = (°C x 9/5) + 32°.
