This can hinder the real-time data transmission necessary for effective monitoring (Iwasaki et al., 2019). Power supply and battery management are critical for the continuous operation of smart sensors. Many farms lack the infrastructure to support constant power supply, making it necessary to rely on battery-powered devices. Efficient energy management systems are required to ensure that sensors remain operational over extended periods without frequent battery replacements (Rahmawati et al., 2023). The accuracy and reliability of sensors are crucial for effective livestock monitoring. Inaccurate data can lead to incorrect assessments of animal health, which can have serious implications. There is a need for ongoing calibration and validation of sensors to maintain their accuracy and reliability (Shohail et al., 2023). 5.2 Economic and logistical challenges The initial investment required for implementing smart sensor systems can be prohibitive, especially for small and medium-sized farms. The cost of purchasing and installing IoT devices and sensors can be a significant barrier to adoption (Arshad et al., 2022). Maintaining and operating smart sensor systems require technical expertise and regular upkeep, which can be challenging for farmers who may not have the necessary skills or resources. This includes the need for regular software updates and hardware maintenance to ensure optimal performance (Rehman et al., 2022). Scalability is a concern for small and medium-sized farms that may not have the resources to expand their sensor networks as their operations grow. The systems need to be flexible and adaptable to different farm sizes and types (Halachmi et al., 2019). 5.3 Data-related concerns Data privacy and security are major concerns when implementing IoT systems in livestock monitoring. The data collected by sensors can be sensitive, and there is a risk of unauthorized access or data breaches, which can compromise farm operations (Neethirajan, 2023). Interoperability between different sensor systems is essential for seamless data integration and analysis. Many farms use a variety of sensors from different manufacturers, which can lead to compatibility issues and hinder the effective use of data (Tangorra et al., 2024). The implementation of smart sensors generates large volumes of data that need to be processed and interpreted. This requires robust data management systems and analytical tools to convert raw data into actionable insights, which can be a complex and resource-intensive process (Rajendran et al., 2023). 6 Case Study: Implementation of Smart Sensors in Dairy Farms 6.1 Background of the selected case study This case study focuses on a dairy farm located in a developing country, where the implementation of smart sensors aims to address challenges in livestock health monitoring and productivity. The farm is characterized by a large herd size, which necessitates efficient monitoring systems to manage animal health and optimize dairy production (Arshad et al., 2022). The farm deployed a variety of sensors, including cow collars equipped with temperature sensors, GPS modules, and heart rate monitors. These sensors are part of an intelligent system that integrates wireless sensor networks (WSNs) and the internet of things (IoT) to provide real-time health data and location tracking of the animals (Rahmawati et al., 2023). The primary objectives of implementing smart sensors on the farm were to enhance dairy production by improving animal health, reduce labor costs through automation, and provide early detection of diseases to prevent outbreaks. The system also aimed to support sustainable farming practices by optimizing environmental conditions for the livestock (Rajendran et al., 2023). 6.2 Outcomes and observations The implementation of smart sensors led to significant improvements in animal health and productivity. The continuous monitoring of vital signs allowed for early detection of health issues, reducing morbidity and mortality rates. Additionally, the automation of environmental controls and feeding systems contributed to increased milk production and overall farm efficiency (Ronald and Raman, 2024). Several challenges were encountered during the deployment of smart sensors, including technical difficulties with sensor accuracy and data transmission, as well as resistance from farm workers accustomed to traditional methods. The integration of new technologies required training and adaptation to ensure effective use (Džermeikaitė et al., 2023). To address these challenges,
