2. Abstract:
One of the essential and basic services to survive on earth is Water. Recent time increasing the
scarcity of water due to growing in population. So this is becoming as a universal obstacle. The
old irrigation system which demands a lot of water, so it needs smart techniques for reducing the
percentage of wasting available water for the irrigation. We have been seeing the increasing of
huge demand for Internet of things in every domain from small and simple applications to large
and complex applications. Practically implementation of a Smart Irrigation is very complex deal,
but association with IoT using Smart wireless sensors it brings a great management system. The
Humidity and Temperature Sensor sense the both water vapor content and temperature around
the plant. The Soil Moisture Sensor sense the soil moisture of a plant, if water content is below
minimum requirement then water will supply from water reservoir using relay and Ultrasonic
sensor measures the water level of reservoir after that sends the data to Microcontroller.
Microcontroller gets the data from sensors, process the data and send to destination through a
IoT.
This project uses regulated 5V, 500mA power supply. 7805/12 three terminal voltage
regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac
out put of secondary of 230/12V step down transformer.
