Nt1310 Unit 5

5. As the team leader, I shared the work among the team members at the initial stage of the project. This improved coordination and helped us achieve intermediate goals of the project. I asked the opinions of my team members and then discussed about various aspects of the project during our daily meetings. We discussed several parts of the circuit design and reached the conclusion that we needed to perform some academic research in order to gain more knowledge about digital temperature sensing circuits. We used books and online technology databases such as ScienceDirect to gain more knowledge, and then created the initial system design.

6. Once the basic design was visualised, we further used the resources available in the electronics department such as the experimentation lab as well as the library

The system was simulated in smaller pieces and the record of the performance of each individual pieced was recorded in a systematic manner. After consulting with our course instructor, we selected the MIC 8085 as the main microcontroller for the project. It was selected, because of its ability to receive signals from an ADC and then perform the required calculations on it. This excellent microcontroller is able to create a library of system values and then display them on the LCD, as requested according to the received input. The intended button for starting the sensing circuit was connected the 7th pin of the integrated circuit. An input to this pin activates the microcontroller into action and also provides power the display unit. Once the controller was activated, I performed the steps for calibration. The standard method of using the freezing point and the boiling point of water is used to calibrate the sensor between the values of 0 and 100. The zero is recorded using ice cold water and the 100 is recorded by putting the sensing transistor in boiling water. The readings were matched with the datasheet that shows the specific voltage values for the device in
