One of the most important infrastructures in contemporary life is pipeline networks. Pipeline networks must be monitored and inspected regularly to ensure their safe and effective operation. Existing monitoring and maintenance approaches are costly and inefficient because pipelines are installed on a large scale and in an inaccessible and hazardous environment. To overcome these challenges, a self-powered radio frequency-based pipeline monitoring system is developed. The developed system comprised mainly three units: An energy harvesting unit, a wireless data transmission unit, and a date receiver unit. The wireless transmission unit is comprised of a pressure sensor that senses the flow pressure inside the pipeline and sends data to the receiver unit with the help of a microcontroller unit. The receiver unit displays the pipeline flow pressure data on a small LCD screen to users for further processing. A 2200 mAh rechargeable lithium-ion battery is used to provide power to the developed wireless sensor node. The rechargeable battery is initially charged with direct AC using a 220 V AC adaptor and T6845-C power management module. Experimental results show that the battery can be recharged from 3.08 V to 4.21 V in a time duration of 300 minutes. Later on, a 10 W solar panel is used to recharge the same battery during sunny and cloudy weather at different light intensity levels. On Suuny day it took 1200 minutes to enhance the battery level from 3.07 V to 4.17 V while on a cloudy day, the battery level enhanced from 3.1 to 4.01 V in a time duration of 1500 minutes. The charged battery is then used to power all the onboard components of the wireless transmission and receiver unit. During the discharging of the battery with data transmission and receiving, it took 1200 minutes to decline the battery level from 4.17 V to 2.97 V.
