In this project most of the electronic circuits are implemented on the Vero board. The main reason to choose the Vero board is simple to use and does not require requirements such as circuit board. On this development board you can easily assemble the components, also the Vero board provides a clear understanding of the cable connection and placement of components other than the PCB where cable connections already established. Vero board is the brand name of the Vero Technologies Ltd company that created this board. Figure 29 Structure of the Vero tab The figure above shows the structure of the Vero tab. Contains regular 0.1 inch sockets for prototyping electronic components. In the Vero board one side is coated with copper strips while the other side is smooth and used for prototyping components with the pins protruding through the holes on the copper-clad side. The copper coating is soldered with solder wire and establishes a connection between various electronic components. The sockets (holes) have enough space for prototyping integrated circuits and other electronic components such as resistors, capacitors, LEDs. In this project two circuits of PIC series microcontroller, RF transmitter and receiver circuits are made on the Vero board with interfacing the desired components. After successfully testing all the circuits on the breadboard, all the circuits are implemented on the Vero board. Some connection issues were faced while creating the connection on this Vero development board. These problems were resolved by discussing the problems with the supervisor, co-supervisors, and friends of classmates. As all the issues have been successfully resolved and the entire project circuit is working as desired and meeting the requirements of the project objectives. The circuit of the Vero board...... middle of the paper...... after the correct functioning of all electronic components The development boars of the PCB and Vero board are made for the final implementation. The state of the ground was tested for the outputs of different sensors and observations were recorded. This table shows the observation of different soil moisture conditions. When soil moisture sensors detect moisture in the soil, it is indicated as 0 and when the soil moisture sensor detects dry conditions, it is indicated as 1 in this table.
