Abstract:
Indian agriculture is dependent on the monsoons which is not a reliable source of water.
Therefore there is a need for an irrigation system in the country which can provide water to the
farms according to their soil types. This paper presents the prototype design of microcontroller
based automatic irrigation system which will allow irrigation to take place in zones where
watering is required, there by supplying required quantity of water depending on the soil
moisture indicated by different plants. Thus different plants grown can be supplied with single
source of water automatically, which requires no human control.
The use of pesticides sprinkling system in this project makes an added advantage to the
irrigation system by sprinkling the pesticide mixture in required proportion to the plants once in
a minute. Here, RFID card is used for giving an input ratio by which the pesticide and water are
supplied to plants.
RFID is an acronym for Radio Frequency Identification. This project is a standalone for
detecting the missing tags in RFID system using AT89S52 microcontroller. This project is useful
in all applications where more than two tags are there. RFID is increasingly used with biometric
technologies for security. Primarily, the two main components involved in a Radio Frequency
Identification system are the Transponder (tags that are attached to the object) and the
Interrogator (RFID reader). Communication between the RFID reader and tags occurs wirelessly
and generally doesn’t require a line of sight between the devices.
In this project we are using two RFID tags with different ratio by which the
pesticide and water are supplied to plants. The input ratio of pesticides will be predetermined in
the RFID tags. This project uses AT89S52 Microcontroller as its controller.
This project uses regulated 5v, 750mA power supply. 7805, a three terminal voltage
regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac
output of secondary of 230/12v step down transformer. The RFID module requires a separate
+5v power supply.
