Development and Implementation of an Automatic Plant Watering System

The aim of this paper is to Automatic watering or irrigation control system has been designed and constructed. The prototype of the system worked according to specification and quite satisfactorily. The system components are readily available, relatively affordable and they operate quite reliably. The system helps to eliminate the stress of manual irrigation and irrigation control while at the same time conserving the available water supply. Improving Irrigation efficiency can contribute greatly to reducing production costs of agricultural products, thereby making the industry to be more competitive and sustainable .It can be seen from the results obtained that the system responded linearly with respect to the degree of dryness for the three soil types. There is a linear relationship between the degree of soil dryness and the time taken to irrigate the soil. At 50% dryness, irrigation duration was 2.0, 2.0 and 2.5 seconds for sandy, loamy and clayey soils respectively. While at 70% dryness, irrigation duration increased to 3.0, 7.5 and 8.0 seconds for sandy, loamy and clayey soils respectively. It is seen that irrigation in loamy soil generally took longer in loamy soil than in sandy soil, and clayey soil irrigation took longest.
