Breathing Air Level Transmitter Monitoring

This paper presents about a monitoring device that can monitor the level of oxygen in fire fighter oxygen tank during rescuing operation. In savings other people life, fire fighters have to risk everything in order to get the mission done. The safety of the fire fighters sometimes is compromised in order to save someone in a burning building or in a burning forest. Any kind of assistance in term of new technology to monitor the condition of fire fighter during rescue mission is necessary and important to the fire fighters community. Oxygen is important to human and continuous supply of oxygen in critical condition during rescue mission is needed for fire fighters in order to perform their rescue operation smoothly. The monitoring system is done by measuring the pressure of oxygen inside the oxygen tank and transmits the data to the computer. The computer will analyse and display the real-time value of oxygen on the screen. An alarm will be activated if the oxygen pressure drops below warning level so that the fire fighter can take immediate action by evacuating the danger area before the oxygen runs out. The system also is equipped with a Carbon Monoxide (CO) sensor that will monitor the surrounding air Carbon Monoxide concentration. Carbon Monoxide is a harmful gas and if humans are exposed to high concentration of CO in the air, it will lead to fatality. This paper also will discuss the method of transferring the data from the oxygen tank using Zigbee wireless technology since it is more convenient for low-power transmission data. Wireless technology is important nowadays as it proves to be a more efficient ways to communicate and transmitting data compared to using wired devices. Zigbee is the latest wireless technology introduced to the world and proves to be a more sophisticated system compared to Wi-Fi and Bluetooth.
