WEEK 7

ACTIVITY:
MAKE A DISCUSSION WITH SUPERVISOR ABOUT CIRCUIT DIAGRAM FOR SUPPLYING WATER TO PLANT.

Date: 16 / 11 / 2016

Objective:

• To make a discussion about the circuit diagram.
• To know the connection of the relay in the circuit.

Content or Procedure:

For the automatic watering circuit, we using Soil moisture sensor to detect the moisture of soil because we do not want to use a Micro-controller and Arduino Uno and make a coding for the instruction of project. We need to discuss with our supervisor because he has knowledge and experience about electronic component. In this circuit, we just use a 3 main component or device to make this circuit automatically supply water to the plant. The 3 main component and device is Soil moisture sensor, Relay and electronic valve. The using of relay in this circuit is to combining two different circuit and power source by controlling in one signal. First Dr, Zulkhairi explain to us about the connection of relay to apply in this circuit. The explanation created by painting on paper about the relay connection. From the connection, we will apply to use it to make our guideline to troubleshoot this circuit.

Result and Analysis:

As a result, we successfully complete combine a 3 component and device until become one circuit for automatic plant Irrigation system. With this circuit, we will testing and troubleshoot to see the functional of the circuit.

Conclusion:

As a conclusion, the circuit has complete and we just need to make a connection and troubleshoot this circuit to see it function. If there is a problem with this circuit, we will soon meet with Dr Zulkhairi to resolve this problem.
