Car Prevent Theft Circuit

Here’s a design circuit for frequency modulation radio controlled anti-theft warning signal can be utilized with any vehicle having 6 – to 12-volt direct electric current power grid. The miniskirt VIRAL HAEMORRHAGIC FEVER frequency modulation sender is climbed on the vehicle at dark, when it is parked in the railcar porch or parking. This is the figure of the circuit;

The recipient CXA1019, an IC-based frequency modulation wireless mental faculty, which is freely uncommitted on the marketplace at a sensible damage, stays inside. The recipient is tuned up to the relative frequency of the sender. When the vector is on and the signs are experienced by frequency modulation receiving set, no sibilation sound is uncommitted at the recipient turnout. Thus transistor T2 (BC548) not to follow up. The outcome is the relay driver electronic transistor T3 has the forward nucleotide preconception via 10k resistance R5 and the relay race is excited. If an trespasser seeks to drive a machine and took him a couple of meters from the auto porch, the link between the railroad car (vector) and alert (recipient) broken.
