• •Fibre optic technology for problem solving i.e. sensing applications.•Approach as opposed to existing sensor designs.•Simplicity and cost effective design. Fiber optic sensors for industrial, consumer, medical and military applications have been reported. Their working principle is majorly based on non-linear optics. For the first time to our knowledge, we propose a cost-effective real time monitoring polarization-based digital signal processing (DSP)-assisted sensor that relies on linear optics for application in earth mass movements due to environmental factors. A sensitivity of 0.075 kg−1 is achieved. This is realized on an average SOP speed of 0.83°/s yielding 598° angular drift on its polarization changes. A sensing performance comparison of single mode fiber (SMF) and large effective area fiber (LEAF) fiber is reported.
