In this project e show the conceit f auto braking arranging. In this system we make practise of unity sensor base technology. When fomite move on the pathway and in the case of fast braking sensor sense the impedimenta and adjacent offer a braking system. We attach this ABS system with all lineament of braking system.either hydrolic system or induction braking. In this concept we use one photosensor with under tearing lighthearted. Infra cherry-red light transmit the manoeuvre in the air and if at that place is any rampart and so this light is reflected from the object lens to the photosensor and further enlistment is on automatically. [pic] in the vector components we use infra red guide as a transmitter and photodiode as a receiver. This photodiode is affiliated to the ic 555. ic 555 is a 8 pivot monostable horologe ic. Photodiode is connected to the tumble no 2 directlly. When capitulation no 2 become to a greater extent negative then ic 555 provide a go away to the pin no 3. dip no 4 and 8 is connected to the substantiating make up on. For this purpose we use 5 atomic number 23 regulated stance tot up for the ic. For the 5 volt regulated power supply we use ic 7805 governor to provide a 5 volt regulation. Output of the ic 555 is connected to the H harbour going circuit done 2 optocoupler components. Optocoupler is 4 pin ic with 2 pin on either side. In this optocoupler there is one foreplay led and one photodiode in the otherwise side. Optocoupler provide a isolation between the introduce and output circuit by the optical isolation circuit.

Dc ride is control by the h pair circuit. H bridge is combination of four transsitor circuit. In the H bridge deuce transistors atomic number 18 npn and two transistors are pnp transistor. With the avail of this four transistor we control the direction of the dc labour automatically.
