Now a day’s the wireless and embedded technologies are enormously used in security managing systems. Here in this project “Wireless Petroleum Level Indicator”, we implemented an AT89S52 Microcontroller based tank level monitoring system for monitoring the fuel level in the tank and to control the thefts.

The system is comprised of Microcontroller, RF Transmitter and Receiver, limit switch for sensing the fuel level, IR Transmitter and Receiver, power detection circuit, GSM Modem, Voice Processing Unit at the receiver terminal of the control room. The systems mechanism is mainly divided into two phases one for sensing unit and the other is alert system.

Sensing circuit (transmitter section):

In phase 1, the transmitter circuit consists of IR Transmitter and IR Receiver; Power Detecting Circuit, RF Transmitter and remote controllers like oil well shutdown alarm, oil well power failure alarm, oil well running and oil theft alarm. Senses the abnormal conditions and sends information to the receiver using the RF transmitter.

Project Title:

Wireless Petroleum Level Indicator

Alerting system (receiving circuit):

In phase 2, the receiving section had RF Receiver and alarm circuit works based up on the signals from the AT89S52 Microcontroller.

Object detection mechanism:

In this project the object the detected by IR light in IR transmitter and IR receiver circuit. Te mechanism of IR sensors in detecting the obstacle is explained in coming sections.

  • Oil well shutdown alarm: For sensing the time of oil well shutdown.
  • Oil well running alarm:  This suggests that the oil well is normal.
  • Power failure alarm: Prevent the transmission line from being stolen.
  • Guard against theft oil alarm: To sound the presence of thief’s.
  • Night patrol alarm: Ensure safe operation of the oil production.
