- 1. Intelligent Irrigation System SubmittedTo :- Ms. YOGITA KUSHAWA Assistant Professor Department of Civil Engineering Delhi Technical Campus Presented By :- Vikas kumar B.Tech (civil) , Third Year 42618003416
- 2. Introduction Irrigation isan artificial supplying of water to the root of plants. The old methods which is use for irrigation are – watering cans , water channels that have to open or close manually. In this case a lot of water is wasted in this process. An automated irrigation system needs to develop to optimize water use for agricultural crops. An intelligent irrigation system has to have all the components that autonomously monitors or control the level of water available to the plant without any failure.
- 3. CONTENT Introduction METHODOLOGY IRRIGATION CONTROL PESTICIDE CONTROL MICRO-CONTROLLER SOIL MOISTURE SENSOR Solenoid-valve
- 4. METHODOLOGY Irrigation usingsoil moisture sensors and Microcontroller. automatically feed plants with water according to their need without farmer’s interference. sprinkle the pesticide mixture uniformly in the desired ratio deserved by the plants automatically Soil moisture sensors help to know the status of the water level in the farm. Solenoid valves for controlling water flow to the farm.
- 5. IRRIGATION CONTROL SYSTEM Use for watering the plant in field. When all the fields acquire sufficient water levels, then the system is programmed to shut off the main motor.
- 6. PESTICIDE CONTROL thismechanism use for mix and spray the fertilizers to the plants in a definite proportion. two motors are needed in order to pump the water and pesticides to a tank where it can be mixed thoroughly .
- 7. MICRO-CONTROLLER Microcontroller ATMEL 89S52is the heart of the system. It is a single chip Microcomputer with I/O ports. It can be used for many control applications like motor speed control, waveform generation etc.
- 8. SOIL MOISTURE SENSOR Soil moisture sensors measure the water content in soil. A soil moisture probe is made up of multiple soil moisture sensors. designed to estimate soil volumetric water content based on the dielectric constant of the soil.
- 9. Solenoid-Valve It isan electromechanical valve for use with liquid or gas. A solenoid is an electromechanical device which allows for an electrical device to control the flow of a gas or liquid. The valve then changes state, either opening or closing to allow a liquid or gas to either flow through or be blocked by the solenoid valve. This is applicable in controlling the hydraulic actions.
- 10. LM324 Comparator Itis integrated circuit use as a motor driver. Advantages of LM324 Comparator are : The LM324 is used as both like comparator and op-amp LM324 is a high-gain electronic voltage amplifier
- 11. Advantages Highly sensitive Work according to the soil condition Fit and forget system Low cost and reliable circuit Complete elimination of manpower System can be switched into manual mode whenever required.
- 12. Disadvantages There arecost in purchasing , installing and maintaining automatic equipment. Sometimes failure will occur.
- 13. Conclusion Automatic irrigationcontrol system has been design and constructed. The system components are readily available , relatively affordable and operate quite reliably. The system help to eliminate the stress of manual irrigation. The prototype of system worked according to specifications.
