1.1 Choose of the temperature sensor After study both sensors. We chose the Tiny Serial Digital Thermal Sensor TC74. We chose the digital sensor because with the other we hadn't the precision that this one give us. With the thermistor the threshold changes all the time and never we can know certainly at which temperature the system will work. We have to think that the digital sensor always give us the exactly temperature with a precision of one degree.

The other advantage of the digital sensor is that we can introduce directly the temperature's value in Celsius. In the thermistor's case first we have to predict the voltage value in certain temperature. After to introduce the value to the program we have convert it to a decimal number.

In the following image we will see the connections schema of the Tiny Serial Digital Thermal Sensor TC74 with the components of the PCB and the PIC ports:
