Smart Helmet

EXISTING METHOD: In the existing method the atmospheric conditions inside the coal mines are monitored inside the coal mines by using sensors but the sensed data cannot be sent to the control room every time it monitors the conditions due this method there is no safety to the people to move inside the mines since the conditions inside the coal mines will not be constant every time. PROPOSED METHOD: In the proposed method we are using zigbee as a wireless technology which is used to send the sensed data to the control room on web page in PC every time it measures the data so that they can also continuously monitor the conditions inside the coal mines so that if any dangerous gases gets evolved inside the they can do an immediate action for protecting the people present inside. The system uses a compact circuitry built around S3C2440 (ARM9) microcontroller Programs are developed in Embedded C. Flash magic is used for loading programs into Microcontroller.
