In our proposed work each time we need to fill the Water bottle/petrol within the car, we simply want to position the right RFID card in accordance with the necessity of amount of petrol close to the RFID reader. Then the ARDUINO reads the information from the RFID reader which in turns drives the ULN IC to additional drive each of the relays for explicit Water/petrol portions and performs the motion in accordance with our/buyer’s necessities.
This method helps in marriage or any perform, we see that even after filling water from water can, if kids or anybody leaves the tab of can open, then the water retains flowing or the water will get wasted. Water saving will enhance with this mission it alsoprovides the safety for the purchasers from varied frauds happens at petrol pump like Brief Fueling of petrol by distraction, Tweaking petrol-dispensing machines utilizing built-in chips.
Right here in our proposed work the amount of Water/gasoline/petrol is determined by the totally different delay time for every digital output pin of arduino, which we supplied throughout arduino programming in order to drive the linked relay for a similar prompt of time which in flip activate the pump in water bucket or tank/gasoline tank for a similar time and in consequence we’ll discover explicit amount of Water/ gasoline/petrol. Right here in our proposed work we use 5 totally different RFID tags for various delay time in order to empty 1/2 liter,1 liter, 1.5 liter, 2 liter and a couple of.5 Liter Amount. A solenoid valve has been used on this mission in order that the move of water doesn’t occur with a lot drive.
The supplies required within the mission are listed in desk 1.
| Elements | Amount |
| Arduino Uno (MOD 1) | 1 |
| EM-18 RFID READER MODUL (MOD 2) | 1 |
| RFID Tags/ Card 125 KHz | 4 |
| ULN 2003 IC (IC1) | 1 |
| Water Pump 220V AC (Pump1 ) | 1 |
| Solenoid Valve 24V DC | 1 |
| 12 V DC Energy Adapter | 1 |
| Relay 5V DC SPST ( R1, R2) | 2 |
Coding
To begin with on this mission we obtained the 12 digit distinctive identification variety of the RFID tag on the serial monitor. To acquire the 12 digit id quantity add the small code to Arduino program proven in fig 2. and join the EM 18 RFID module in accordance with fig 3.
Now Put RFID Tag in entrance of RFID Reader Module and See the 12-digit decoded worth.
Right here the decoded values for my RFID Tags are as observe (Refre desk 2).
Subsequent put together the code tht verify the RFID card quantity after which give sign to relay to dispense the water in accordance with RFID card right here it’s good to change and set the cardboard ID quantity in accordance with tour RFID card ID quantity.
Subsequent join all compoennst in accordance with following circuit diagram
Testing
At any time when an individual will put the RFID tag in entrance of the RFID reader, each the relays shall be ON,The primary relay is to drive the water pump motor/Gasoline pump motor and the second relay is to drive solenoid valve. Right here on this proposed mission we use ULN2003 relay driver IC to drive each the relay. We discovered that our circuit connection can fill half a liter of water/gasoline in 16 seconds which means 1 liter in 32 seconds, 1.5 liters in 48 seconds, 2 liters in 64 seconds or 2.5 liters in 80 seconds. So each time we need to fill half liter of water/gasoline now we have to drive the relay constantly for 16 second and so forth for various Amount.
