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.
