LIFE SAVING KIT IN LMV

LIFE SAVING KIT IN LMV

Objective

To save human lives from exposure of harmful gases by preventing Oxygen content deficiency inside LMV.

For human survival, the atmosphere Oxygen level should be maintained between 19.5% to 23.5% (V/V in air).

Few poisonous gases do not show any symptoms like suffocation or eye irritation.

By nature, human will not be able to identify such hazards.

So, we need some external source to identify, handle & overcome such hazards.

Our project acts as a source to identify, handle & overcome such hazards.Project Background

In the recent past, we came to know about the deaths, which occurred inside the LMV by inhaling harmful gases and subsequently, leads to deficiency of Oxygen content.

Working Principle

If the Oxygen level inside the LMV reduces below (i.e. below 19.5) the safety limit, Oxygen sensor senses it & gives feedback to the micro controller. The micro controller activates the alarm and the window operating D.C. Motor opens the LMV windows.

This allows the atmospheric air to enter inside the LMV and maintain the Oxygen level and carry away the poisonous gas.
