Abstract

Soldiers are the Army’s most important resource. Soldiers play a vital role to protect one’s country. The term soldiers include service men and women from the Army, Air Force, Navy and Marines. They will always be the one responsible for taking and holding the duty in extreme whether conditions through out the year. While providing security to the nation, they may face troubles in extreme hot/cold whether conditions.Both very cold and very hot temperatures could be dangerous to health. Excessive exposure to heat is referred to as heat stress and excessive exposure to cold is referred to as cold stress. In a very hot environment, the most serious concern is heat stroke. At very cold temperatures, the most serious concern is the risk of hypothermia or dangerous overcooling of the body. In this project we are going to design an E-Uniform which gives better protection to the soldiers who are working in extreme whether conditions. This Uniform will make the soldier to work in any kind of environment. Here we are using Solar Panels to power up the internal circuitry of the E-uniform. A 12 V DC lead acid rechargeable battery is used for storing the energy. We are using conventional battery charging unit also for giving supply to the circuitry.
AT89S52 microcontroller is the heart of the circuit as it controls all the functions. A voltage sampler is interfaced with the system using ADC 0808 to get the voltage generated from battery as a display on a 16X2 LCD.The project is operated in two modes summer mode and winter mode. By selecting the mode of operation, it can drive body heater/cooler. The heater/cooler in turn will help us to provide chilling or warming effect inside the uniform which helps the soldier to bear to any kind of external environment and he can work efficiently without heat stress or cold stress.
This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the acd output of secondary of 230/12V step down transformer.
