Farmers around the world face the problem of meeting crops' water needs, especially those farmers in third-world countries. It is from this global problem that the inspiration to modify a time-based smart irrigation system that will not only optimize water resources management but also significantly reduce the required manpower for crop production was drawn. This system consists of three blocks, which include input or data collecting block, controller data processing block and output/actuator block. From the experiments, the following observation was made: from a particular soil sample with constant percentage of soil dryness 100%, it can be seen that the soil moisture content increases with an increase in irrigation, for instance, clay, loamy and sandy soils at 100% soil dryness, the soil moisture content increase from 8.7% to 26.5%, 8.6% to 26.0% and 7.4% to 12.3% respectively for irrigation time of 5, 1o and 15secs. Also, taking a constant irrigation time of 15secs for instance, and testing soil samples of different dryness of 100%,75%,50%,25% were decreased in soil moisture content after irrigation of 15secs to 26.5%,20.2%,13.4%,7.5% of clay, 26%,20%,13%,7.3% of loamy and 12.3%,11.7%,9.8%,7.3% of sandy soils respectively. With this, it could be seen that clay soil showed a higher tendency to hold more moisture than loamy and sandy soil, and sandy soil holds the least moisture compared to other soil types.
