RFID Reader & Arduino-Uno Interfacing Based Automatic Restricted Quantity Water/Petrol Dispenser

In our proposed work whenever we want to fill the Water bottle/petrol in the vehicle, we just need to place the correct RFID card according to the need of quantity of petrol near the RFID reader. Then the ARDUINO reads the data from the RFID reader which in turns drives the ULN IC to further drive both of the relays for particular Water/petrol quantities and performs the action according to our/customer’s requirements.

This system helps nn marriage or any function, we see that even after filling water from water can, if children or anyone leaves the tab of can open, then the water keeps flowing or the water gets wasted. Water saving will increase with this project it alsoprovides the security for the customers from various frauds occurs at petrol pump like Short Fueling of petrol by distraction, Tweaking petrol-dispensing machines using integrated chips.

Here in our proposed work the quantity of Water/fuel/petrol depends on the different delay time for each digital output pin of arduino, which we provided during arduino programming so as to drive the connected relay for the same instant of time which in turn activate the pump in water bucket or tank/fuel tank for the same time and as a result we will find particular quantity of Water/ fuel/petrol. Here in our proposed work we use Five different RFID tags for different delay time so as to drain 1/2 liter,1 liter, 1.5 liter, 2 liter and 2.5 Liter Quantity. A solenoid valve has been used in this project so that the flow of water does not happen with much force.

The materials required in the project are listed in table 1.

Coding

First of all in this project we obtained the 12 digit unique identification number of the RFID tag on the serial monitor. To obtain the 12 digit id number upload the small code to Arduino program shown in fig 2. and connect the EM 18 RFID module according to fig 3.

Now Put RFID Tag in front of RFID Reader Module and See the 12-digit decoded value.

Here the decoded values for my RFID Tags are as follow (Refre table 2).

Next prepare the code tht check the RFID card number and then give signal to relay to dispense the water according to RFID card here you need to change and set the card ID number according to tour RFID card ID number.

Next connect all compoennst according to following circuit diagram

Testing

Whenever a person will put the RFID tag in front of the RFID reader, both the relays will be ON,The first relay is to drive the water pump motor/Fuel pump motor and the second relay is to drive solenoid valve. Here in this proposed project we use ULN2003 relay driver IC to drive both the relay. We found that our circuit connection can fill half a liter of water/fuel in 16 seconds that 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 whenever we want to fill half liter of water/fuel we have to drive the relay continuously for 16 second and so on for different Quantity.
