WEEK 10: 12TH OCTOBER 2012

Title           : Testing the LCD, bulb, and thermistor sensor                                 circuits.

Objective   : To make sure the circuits are function well.

Procedure : 1) The LCD circuit had been tested. When the                                    toggle switch (as shown in Figure 1) been ‘on’, the                          system will start operate by displaying ‘SMART                              CHICKEN COOP LOADING!!!’ (as shown in                                    Figure 2) followed by the surrounding                                              temperature, the percentage of humidity, and the                            condition of fan, bulb, and feeder motor (as shown                          in Figure 3) at the 20x4 LCD.

 Figure 2: The system will start operate by displaying ‘SMART CHICKEN COOP LOADING!!!’

Figure 3: The surrounding temperature, the percentage of humidity, and the condition of fan, bulb, and feeder motor

                2) Next thermistor sensor had been tested. When the                         surrounding area is in room temperature, the bulb will                     turned ‘on’.

              Figure 4: Thermistor sensor in room temperature

                                 Figure 5: The bulb turn ‘on’

                  3) The thermistor had been burn by using the lighter.

                   Figure 6: Thermistor sensor is above 30°C

                                Figure 7: The bulb turn ‘off’

Results: 

             

Conclusion: The LCD, bulb, and thermistor sensor circuits are                            function well.
