Online Monitoring and Transfering of Geological Gases Data through Zigbee

Global warming is making all the Scientists, Engineers and Doctors to think and act in each and every movement. A predictable rise on the Earth’s temperature is mainly due to the carbon dioxide levels exceeding the pre-industrial threshold levels, which in turn is effecting the global climate atmospheric concentrations. The monitoring of these gases is very important for effective control of the atmosphere pollution levels to a permissible limit. The data obtained from the sensors are transferred to the receiver side through Zigbee communication. The main purpose of this paper is to implement a control system which will keep a track of the concentration of different gases, and would alert the higher authorities or control engineers in case the concentration goes above the set threshold levels. Sensor’s resistance would change depending upon the concentration of the gas, which will change the voltage. This change can be tracked by the microcontroller to convert the analog data into digital data, and transfer it wirelessly to the base module.
