This integrated sensor system offers practical benefits for advanced farm management by enabling GSM-based remote monitoring, which can optimize resource allocation, enhance decision-making and boost agricultural productivity, marking a step towards more sustainable and profitable farming practices. It contributes to the smart farming literature by demonstrating the application of precision agriculture models and addressing technological adoption challenges (Aggarwal and Singh, 2021). However, the reliance on GSM and setup complexity present limitations, pointing to future research directions towards alternative connectivity methods and more user-friendly, cost-efficient systems (Thakur et al., 2020).
       
The integration of Internet of Things (IoT) technologies into precision agriculture, as explored in our research, sets a strong foundation for the next steps in smart farming innovations (Dixit et al., 2020). Future research can greatly benefit from incorporating advanced data analytics and machine learning to improve decision-making (Shivappa et al., 2024).
