SAFTY CONSIDERATIONS IN SAFTY CONSIDERATIONS IN AUTOMOBILES USING MULTIPLE AUTOMOBILES USING MULTIPLE

SENSORSSENSORS

In this miniproject an automobile systems is designed in order to address safety features for preventive measures Viz:

Fuel quantity Fuel leakage Engine coolant replacement/refilling using

1.Fluid level sensor

A general sub system consist of three sensors used to safe guard two basic operations like,• Fuel monitoring• Engine temperature detector

Our project was broadly classified into six phases:

1.Idea development.2.Component identification.3.Software identification.4.Bread board verification of designed circuit.5.Microcontroller study and programming.6.PCB fabrication and soldering.

CIRCUIT DIAGRAM

Since the hardware complexity is much lower in our miniproject with PIC 16F877A. The delay involved will be much lower and hence negligible.

However the delay in the program execution loop = 1000ms This delay is provided to protect the out put produced and avoid overlapping effects

Data acquisition

*Problem analyzing &solving

* Provide security
