Theft of gasoline / diesel from parked vehicles is quite common. Here is an audio-visual circuit against the gasoline theft alarm that can help prevent this crime. The circuit consists of transmitter and receiver sections. The transmitter has to be mounted on the vehicle near the gas tap, and the receiver in the common room of your house.

The transmitter section (shown in Figure 1) is constructed around an infrared LED (IR LED1), a photodiode (PD1), an IC comparator 741 (IC1), an IC phase blocking loop 567 (IC2), an Transmitter 433MHz (TX1) and a few discrete components. The circuit power is supplied by the vehicle's 12V battery via the S1 switch.
When someone approaches IR LED1, the IR signal reflected from the subject is detected by the PD1 photodiode. A voltage difference appears on the inverter pin 2 of IC1 and its pin 6 is raised. As a result, the npn transistor T1 leads and allows the PLL 567 to transmit a prefix frequency through the TX1 transmitter. LED1 lights up when a signal is transmitted.

The receiver section (shown in FIG. 2) is constructed around an infrared receiving module (RX1), PLL 567 (IC3), EFY-KnS development board 8051 together with some discrete components. It works with a 9V-12V battery. Alternatively, you can use a 12V adapter. Switch S2 is used to power the circuit.
The frequency transmitted from the transmitter is received by the RF receiver module (RX1) and decoded by PLL567 (IC3). The IC3 output is fed to the input pin P1.1 of the EFY-KnS development panel 8051. The output input pin P2.2 is connected to the transistor T2 to drive the buzzer and the LED2. The EFY-KnS 8051 development board is used for rapid development and is available at EFY Kits'n'Spares (KnS) partners.
The software is written in 'C' language on the demo platform KEIL version 4.0. The programming of the development board is simple and is mentioned in the manual provided with the development board.
Mount the transmitter and receiver circuits on two separate general purpose PCBs. Connect the vehicle battery to the transmitter circuit. Set the IR1 LED and PD1 photodiode of the transmitter so that if someone approaches the gas tap, a signal can be transmitted through TX1. It would be best if you used a small 10mm cable as an antenna.
Mount switch S2 on the front of the receiver unit together with LED2 and buzzer. Install the receiver's PCB in your residence. When the receiving module receives a signal from the transmitter, LED2 will illuminate and the buzzer PZ1 will sound at the same time.
