Week 26

 Creating prototype of model on stripboard.

Before this, all the component and equipment are tested on a breadboard, as for the prototype of a model, it is best to solder the circuit of model on a stripboard as it is more neat and genuine. These prototypes are assembled and soldered together on a stripboard designed for permanently building one-off circuits. The board is constructed with insulating material, which is often a resin-bonded plastic or fiberglass. The circuit will be sleeker and more methodical when constructed on a stripboard, however with large number of holes, it is remarkably easy to connect a component in the incorrect position.

 

A prototype model of circuit 

As the product design are completed, then it is review and tested on field. The video below shows the functionality of the product design. 

From the video above, it shows that when the water level detects from 0 to 15 cm, the green LED will light up showing that the water level is in good condition. Once the water level is in the range of 15 cm to 30 cm, yellow LED will light up with low buzzer sound. This low buzzer is as an alert notification for farmer where they need to be alert on the water level in the field. Lastly, when the water level is above 30 cm, meaning the water level in the irrigation system is very low, therefore red LED will light up with high buzzer sound. The high buzzer sound is to notify farmers that the water level in the field is in critical situation, therefore farmers need to take consequences action on opening the drainage for the paddy field.
