INCREASING SAFETY OF BOMB DISPOSAL MISSIONS- A BODY

SENSOR NETWORK APPROACH

AIM:

The main aim of the project is to implement a wireless communication system in the field of

electronics by which we can collect the data from the person section where sensors are placed.

PURPOSE:

The purpose of this project to increase the safety of operatives in missions through monitoring,

fusion of health information, and remote alerts.

DESCRIPTION:

In this project there are two sections. The first section is person section and another

section is base section. In the person section the temperature sensor will sense the body temperature of

the person and sends to the ADC pin of the ARM board .ADC will convert this information and send to

the micro controller. Person position is recognized through mems technology, mems can take that

information and sending to micro controller. By sending all this information to base section through

zigbee transreceiver. Micro controller displays this information in the LCD and in the PC. And at the

person section if the person feels hot at that time automatically dc motor is on to cool her body.

TECHNOLOGY:

ZIGBEE:

Now a day's every system is automated in order to face new challenges. In the present days

Automated systems have less manual operations, flexibility, reliability and accurate. Due to this demand

every field prefers automated control systems. Especially in the field of electronics automated systems are

giving good performance. And this is realized by making use of Zigbee technology for communication.

Zigbee is new wireless technology guided by IEEE 802.15.4 Personal Area Network standard. It is

primarily designed for the wide ranging controlling applications and to replace the existing non-standard

technologies. It currently operates in 868MHz band at a data rate of 20Kbps in Europe, 914MHz band at

40kbps in USA, and the 2.4GHz ISM bands Worldwide at a maximum data-rate of 250kbps.

RESULT:
