WORKING
Speed governor
is an essential system to avoid over speed of vehicles. So we have introduced a
smart Speed governor system. This system consists of micro-controller, Alcohol
detector GPS, GSM, RELAY and alarm system. When the speed reaches near to predefined range
alarm system will wake up. If limit crosses message is sent to authorities
through GSM and corresponding location is also sent through GPS.. The corresponding
location is read and sends SMS to authority. The engine can be start if no
alcohol present.
The speed sensor detects the speed
of the vehicle. Piezo sensor will detects if any accident is happened and it
sends a message signal to the respective authorities through GSM. Alcohol
sensor will activate when alcohol presence is activated and it will turn off
the vehicle.
