·
These all above components are monitor
and controlled by microcontroller.
·
The controller use in this system is of
40 pins and it has 4k bytes of ISP i.e. (In System Programmable) flash memory
and its operating range is 4.0v-5.5v and consist of 128 x 8 internal memory.
·
The components which are installed in
box are not directly connected to controller because the output of components
is analog in nature and controller accept only digital so for that purpose ADC
is use which converts analog input into digital output.
·
Temperature sensor’s output, flex
sensor’s output and accelerometer’s output is given to ADC as inputs.
·
Digital equivalents of these inputs from
ADC’s output are given to microcontroller as inputs.
·
GSM stands for Global System for Mobile.
It is a module which is use to send messages regarding to car temperature or
any damage to car or it has met to accident. And it is connected to TX pin of
controller.
·
In this system GPS is use for locating
and tracking the location of vehicle. It also calculate the geographical
position of module. And GPS is connected to RX pin of controller
