An effective indoor ventilation system will significantly reduce the risk of bacteria and viruses infection. The performance of an indoor ventilation system is determined through CO2 concentrations in closed room environments of offices, schools, hospitals, shops, and factories. In the current Covid-19 epidemic, indoor facilities need an optimal CO2 monitoring system to reduce the risk of Covid-19 infection and overcome the following difficulties:
Hydroponics is a model of the high-tech application in agriculture. With this model, plants grow without soil and use nutrient solutions in water. When the farmer applies an intelligent hydroponic system, the plants grow quickly with uniform product quality and yield from 30 to 40% higher than conventional cultivation. The application of the automated hydroponics system helps to overcome the following difficulties of traditional farming:
Sensors are available everywhere at factories, and they are present in all systems for measuring parameters such as steam pressure, pipeline temperatures, water tank level. Although there are different types and brands, the sensors usually have an output of analog signal 4-20mA and are connected to the center by a signal wire. Therefore, if the factory adopts a wireless sensor network, it will help to eliminate the difficulties of a wired network as follows:
Warehouse always be an essential part of the logistics supply chain. Storage of specific goods such as foods, agricultural products, pharmaceuticals or vaccines, requires a stringent demand of temperature & humidity conditions. Therefore, to ensure the preservation of the goods, the warehouse operation unit has to apply a temperature humidity monitoring system to track environmental conditions. However, traditional monitoring solutions still have some shortages:
