Objective: To identify the overall picture of the system of the project.
Analysis/Procedure:
After Hours of research, I have created a block diagram of the system. This is only a draft block diagram which shows the components needed to build this project. Below is the block diagram:
Explanation:
- The speedometer have two sensors installed at the meter display.
- There are two sensors that is installed at the meter display which are located at 80 KM/H and 100 KM/H
- If the needle of the meter crosses the 80 KM/H, it will automatically send an data to PIC.
- If the needle of the meter then crosses 100 KM/H, again, it will automatically send data to PIC.
- If the PIC detects and receives a data from a sensor, it will send signal to RS232 to TTL device and shows a alert at the LCD display simultaneously.
- RS232 to TTL will convert the analogue signal from PIC to digital signal before transmit to GSM module.
- Then user will receive this signal as a SMS application in their mobile phone.
Conclusion:
I need to identify and make researches about all the components needed.
