PIC18LF4620 based customizable wireless sensor node to detect hazardous gas pipeline leakage

The paper describes the performance and functional characteristics of PIC18LF4620 based wireless sensor node in monitoring the parameters such as CO₂, Oxygen, temperature, humidity and light around the pipeline structure. The system is deployed to monitor any deviations in these parameters with the standard atmospheric values eventually alert the user even to a remote location. The proposed system is a battery operated wireless sensor node which is interfaced with the external sensors to measure the parameters listed above. The distance range between sensor node and coordinator node is also tested. The signal conditioning module associated with detailed calibration procedure for the individual sensor is also described. Zigbee protocol stack is implemented to enable wireless transmission and performance of the same is evaluated.
