WEEK 13: 25TH OCTOBER 2012

Title             : Testing and demonstrating all the components and                         circuits of the Smart Chicken Coop.

Objective    : To make sure all the component and circuit are                               function well as been plan according to the                                       flowchart.

Procedures : 1) The thermistor and humidity sensor operation                                  had been shown in Video 1.

                       2) The water level sensor operation had been                                      shown in Video 2.

Results:

Video 1: Testing the bulb and fan

1) For the bulb, when the temperature in the chicken coop was 30°C and below, the bulb will turned ‘on’ to produce heat in the chicken coop. The bulb will remain turned ‘on’ until the temperature inside the chicken coop was 30°C and above, then it will turn ‘off’. It will remain turned ‘off’ until the temperature was 30°C.

2) For the fan, when the humidity in the chicken coop was 59% and below, the fan was turned ‘off’. The fan will remain turned ‘off’ until the humidity was 60% and above, then it will turned ‘on’ to give an air circulation in the chicken coop because the humidity was high.

Video 2: Testing the water pump

3) The water pump was turned ‘on’ and remaining refill the water in the container inside the chicken coop when the water was getting empty. At this time, the water level sensor will detect the water in the container inside the chicken coop was in a low level. It will stop refilled the water from main supply water outside the chicken coop when the water level sensor detect the water was getting full. At this time the water pump was turned ‘off' automatically. 

Conclusion: Overall, this project was successfully function according to the flowchart. The current problem encountered was the bulb was blinking sometimes. This is because temperature is always changing and unexpected. It was blinking when there was an interchanging between 30°C and 31°C. The adapter that been used in this project are also not enough supply current because when the water pump was turned ‘on’ the bulb and LCD was blinking and unstable. This problem can be overcome in future by changing the adapter that has high current than the existing that been used in this project.
