| Summary: | As water supply is becoming scarce in today’s world there is a necessity of adopting automated ways of irrigation for plantation. The manual irrigation method is highly depending on human or animals support to function in order to flow the water to the plants. This leads to producing an ineffective water system which leads to water wastage and affects the growth of the plants. This project aimed to implement automated irrigation system to irrigate the plants automatically in order to reduce water wastage and to encourage the growth of the plants and also to save the soil moisture value occasionally in cloud. In addition, this work proposes to deploy PIR sensor to safeguard the plants from being harmed by humans and animals when the plants left unattended especially at night hours. In the first phase of implementation, the proposed automated irrigation system is built as a prototype in which it helps in conserving water through soil moisture sensor which will take readings of soil moisture values. If the moisture values are lower than 50%, then the water is supplied automatically from the motor pump to the plants. While if the value rises above 50%, then the motor pump will be turned off automatically. The proposed system maintains the desired soil moisture level and sends the data to Arduino which acts as the controlling unit. In addition to that, the readings from the soil moisture sensors will be sent to Blynk mobile application for user’s monitoring and viewing purposes. The performance of the proposed system is evaluated against manual watering method to irrigate papaya plants for five weeks. In this experiment, it was observed that the papaya plants irrigated by the proposed system grew taller and healthier as compared to the manual watering method. This is because the water is supplied to the plants according to their needs which eventually encouraged their growth. In addition, by this, water wastage is reduced too. Furthermore, it also able to save the soil moisture value occasionally in cloud. The soil moisture value will be saved in the cloud for every 7 hours of interval for further analysis. The accuracy of this data storage has been tested using the Arduino Ide which displays the same value as the value stored in the cloud. In the second phase of the implementation, PIR sensor is included in the proposed automated irrigation system. It helps to detect the intruders in order to protect the plants from being harmed or destroyed especially at night hours. The accuracy of the PIR system was validated by conducting experiments with hindrance and without hindrance. From the result obtained, it was observed the PIR sensor is able to detect the intruders within six-meter range and constantly alert the users. |
