- 2. Contents • Irrigation • Microcontrollers • Block diagram • Components and devices used • System software • Conclusion 20/01/2016 2
- 3. IRRIGATION • Latin for ‘moist’ or ‘wet’ • Means purposeful wetting of something. 20/01/2016 3
- 4. TYPES OF IRRIGATION • Surface irrigation • Subsurface irrigation • Overhead irrigation Sprinkler irrigation 20/01/2016 4
- 6. MICROCONTROLLER • A microcontroller is a selfcontained system with peripherals, memory and a processor that can be used as an embedded system. • Also called Embedded Controller 20/01/2016 6
- 7. Applications of Microcontrollers • Used in automatically controlled devices including power tools, toys, implantable medical devices, office machines, engine control systems, appliances, remote controls and other types of embedded systems. 20/01/2016 7
- 9. Sensors and Comparators • Sensor is a type of transducer. • Measures a physical quantity in order to convert it into an electronic signal • Sensor HIH 4030 measures relative humidity and produces linear analog. • Comparator compares data with a reference value. 20/01/2016 9
- 10. Humidity Sensors • A humidity sensor (or hygrometer) senses, measures and reports the relative humidity in the air. It therefore measures both moisture and air temperature. 20/01/2016 10
- 12. Relay logic • . Method of controlling industrial electronic circuits by using contacts and relays 20/01/2016 12
- 13. Interfacing card • PCL series card 207 is used for ADC/ DAC signals required by the system 20/01/2016 13
- 14. STEPPER MOTOR • Electromechanical device which converts electrical pulses into discrete mechanical movements 20/01/2016 14
- 16. Merits • Highly sensitive • Works according to the humidity level • Can handle heavy loads up to 7A. • System can be switched into manual mode whenever required • It helps to increase the production from 25 to 30 %. 20/01/2016 16
- 17. Conclusion • The developed microcontroller based irrigation system can work constantly for indefinite time period, even in certain abnormal circumstances. • It is also possible to correct the various parameters through the controller programming. 20/01/2016 17
