This document describes a wireless fuel level sensor system using radio frequency. The system consists of a transmission section and receiver section connected by an RF module. The transmission section uses liquid level probes connected to a microcontroller to detect the fuel level and encode the data. The encoded data is transmitted via an RF transmitter. The receiver section receives the data via an RF receiver, decodes it using a decoder, and sends it to another microcontroller connected to an LCD to display the fuel level. The system provides automated and wireless fuel level detection with low power consumption.

- 3. Fuel or liquid level needs to be maintained in various situations and places, as in domestic purposes i.e., in water storage tanks, Industrial maintenance like cooling mechanism etc. The liquid level needs to be maintained to a particular constant level to avoid complications.
- 4. The fuel level indication system in the Previous generations would be like as shown in the figure. These type of systems are very bulky and tough to make. These are valid only up to few meters. So the technology has been increasing rapidly, everything has made wireless.
- 5. The Fuel level indicator is said to be one of the important part In the fuel systems. As per the previous technology, the petrol level indication used in fuel systems are wired and are very bulky. So, as per the development of technology, The Fuel level sensing techniques used in petrol tanks are wireless. The petrol level sensor mainly consists of two blocks i.e., transmission and receiver sections which uses Radio frequency. This reduces the complexity of the level indication.
- 6. Hardware and Software Hardware we used ? ? • AT89S52 Microcontroller • Power supply • RF Transmitter and Receiver • Encoder and Decoder • Liquid Crystal Display (LCD) Software we used ?? • Embedded ‘C’ • ISP to burn Chip • RIDE to write code
- 8. What's happening?? The Probes of Sensors are placed in the tank and are connected to ports (P3.0- P3.7) of micro controller. The sensor ports will be enabled when the fuel level touches the probes . According to the code given to micro controller and signal of the sensors, the microcontroller sends the data to the encoder connected to the ports( P1.0 – P1.3) of micro controller. The encoder encrypts the data and sends it to RF transmitter, the RF transmitter sends the given data to RF receiver.
- 10. What's happening ?? The data that is sent by RF transmitter is received by RF receiver. The RF receiver is connected to decoder which decrypts the received data. The decoder is connected to Pins(P 1.0- P1.3) of micro controller. The micro controller receives the data and processes according to the code and it sends the respective result to the LCD which is connected to pins(P 2.0- P2.7) of micro controller. The LCD receives the data sent by the micro controller and displays the respective result .
- 11. WHY MICROCONTROLLER? ? • A microcontroller is a single-chip microcomputer which contains RAM , ROM , CPU , I/O ports , ADC and other peripherals. • It has fixed amount of RAM , ROM , I/O ports. • It is also called embedded microcontroller because it is designed for embedded systems performing specific tasks only. • Microprocessor only has CPU , ALU, stack pointer, program counter and other registers ,clock timing circuit. • Microprocessor does not have RAM, ROM and I/O ports • It requires large space and it’s cost is higher as compared to microcontroller.
- 12. AT89S52 The AT89S52 is a low power high performance 8-bit micro computer, and it is designed using Atmel’s high-density nonvolatile memory technology. The main advantages of 89S52 over 8051 are 1.Software Compatibility 2.Program Compatibility 3.Rewritability The 89S52 micro controller has an excellent software compatibility, i.e. the software used can be applicable to any other micro controller. The program written on this micro controller can be carried to any base. Program compatibility is the major advantage in 89S52. The program can be used in any other advanced micro controller. The program can be reloaded and changed for nearly 1000 times.
- 13. Regulated Power Supply A regulated power supply is an embedded circuit that converts unregulated AC into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage to a circuit or device that must be operated within certain power supply limits. The output from the regulated power supply may be alternating or unidirectional, but is nearly always DC
- 14. Some features of 89S52 are: 8-bit data bus. 16-bit address bus. 32 general purpose register each of 8-bits. 16 bit timers. 3 internal & 2 external interrupts. 16 bit program counter & data pointer. Bit as well as byte addressable RAM area of 16 bytes PIN DIAGRAM
- 15. RF Module An RF module is a small electronic circuit used to transmit and receive radio signals. RF modules are most often used in medium and low volume products for consumer applications such as garage door openers, wireless alarm systems, smart sensor applications, and wireless home automation systems. They are sometimes used to replace older infra-red communication designs as they have the advantage of not requiring line-of-sight operation. Several carrier frequencies are commonly used in commercially-available RF modules, including 433.92 MHz, 315 MHz, 868 MHz and 915 MHz . RF module has Transmitter and Receiver modules.
