Appendix 2: User manual (hardware, software)
Step 1: Plug in the power to the system, wait a while for the system to start up.
Step 2: After booting is complete, the LCD screen will display a screen including
temperature, air humidity, soil moisture, current Auto/Manual mode, and Wi-Fi connection
status.
Step 3: Download and log in to the Blynk App on your smartphone (if you want to know
how to log in to this project, please contact the author of this topic).
Step 4: After successful login, the system will run by default in AUTO mode and show an
area to display the values of sensors, real-time video from the camera, heat graphs sent up
from the system. There is also an area to set the value of soil moisture, temperature, if the
actual value is greater than the set value, the system will automatically turn on the light,
fan or water pump.
Step 5: If it is required to switch to Manual mode, by pressing the Mode button, there will
be an area displaying the status of the devices in the system, and there will be buttons, if
