Intensive pig farming, also known as the ‘intensive piggery system’, has become the primary method of farming in the pig industry. According to this method, pigs are housed indoors and confined in individual stalls or straw-lined sheds at high stocking density, while keeping pigs of similar ages to live together in large crowds under common environmental settings. By doing so, feeding efficiency is significantly improved, and emerging technologies are often employed to maintain pig health and safeguard pig growth - monitoring various environmental parameters inside the barns with wireless temperature and humidity sensors is an exemplary case in point.

The Need for Continuous Asset Tracking
Of the many complexities along the global supply chain and daily logistics operations, asset tracking is arguably the most challenging. Disruptions and subsequent capital loss not only affect goods transported worldwide, but also containers and vehicles used for shipment. On a more local scale, retail stores and shop owners are challenged in keeping track of their assets and supply at all times throughout the day for reasons varying from theft prevention to inventory management.
