Emergency power packEmergency power pack

The emergency power pack has been developed to assist tourists during their journey. A solar panel and a small turbine were attached to the portable power pack to charge the battery while there is no proper power supply source within the area. Besides this power pack is equipped with a Global Positioning System (GPS) and Global System of Mobile Communication (GSM). Simply by pressing the switch, they can send SOS messages to call for help.

Why you need emergency lighting module power pack?

The emergency power pack is the best tool to assist the tourists. The unique thing about this power pack is it has portable battery. This power pack has Global Positioning System (GPS) and Global System of Mobile Communication (GSM). With GPS service you can send message to any relative if you are stuck in woods.

How emergency power pack work?

In Emergency power pack we have interfaced different circuits with each other as shown in figure below.


  • Solar Panel
  • Small Turbine
  • Micro Controllers
  • Liquid Crystal Display (LCD)
  • Global System for Mobile Communication (GSM)
  • Global Positioning System (GPS)
  • Rechargeable battery
  • Universal Serial Bus (USB)

When we turn on the device and press the button then GSM will send your location on the mobile number you added.

We have used Solar panel energy for generating electricity in the day time and at night we have used small water turbines to change this system. The controller is also used to provide the optimum charge to the batteries and will protect the battery from the damage due to overcharge, deep discharge, and changing voltage levels. To charge this system using an external source USB port is available. Arduino is used for control purposes and GSM for sending the message. LCD is used to display our Location.
