Week 28: Set up the Hardware

OBJECTIVES: 1. To set up the hardware for my project.
            2. To solder the component on a strip board.

METHODOLOGY: 1. Connect the NodeMCU with the relay.
             2. Connect relay with water pump motor.
             3. Soil moisture sensor is connected with the NodeMCU.
             4. Set up Blynk application with the system.

RESULT:

Figure 35: Display on Blynk application

ANALYSIS & DISCUSSION: When the sensor detected the moisture of the soil, the led on the sensor will turn on. However, when the sensor detect the soil is dry, the led on the sensor will turn off and it will trigger the motor to on and pump the water. When the sensor detected the moisture of the soil, it will send the signal to NodeMCUand it will send the status of the plants on Blynk apps.

CONCLUSION: All the objectives are achieved. The hardware is successfully set up and all the components have been solder.
