Block Definition


Monitor eye blink and input given to microcontroller
Microcontroller digitize the given data and then processes it control the ignition control unit.
Microcontroller gives corresponding data to driver circuit unit and then ignition control section, control the driver
Alarm section connected to this device which provides corresponding alarm signal to person who drives
Status indicator indicates corresponding status of the person



Alcohol sensor


Detect alcohol consumption
Connected to microcontroler
When detected , voltage rises


Eye blink sensor


it checks the drowsy condition
connected to microcontroller


Power Supply – Circuit Description


The operation of power supply circuits built using filters, rectifiers, and then voltage regulators. Starting with an AC voltage, a steady DC voltage is obtained by rectifying the AC voltage, Then filtering to a DC level, and finally, regulating to obtain a desired fixed DC voltage. The regulation is usually obtained from an IC voltage regulator Unit, which takes a DC voltage and provides a somewhat lower DC voltage, Which remains the same even if the input DC voltage varies, or the output Load connected to the DC voltage changes.
