JNC upholds the philosophy of “Human Health and Planet Sustainability, dedicating itself to protecting the health of the Earth through the development of products that support the creation of smart green urban microclimates. In addition to air quality and flood prevention, water pollution, as well as the monitoring of wind speed, wind direction, and rainfall, are also key indicators in smart green city planning. Water quality monitoring is essential for ensuring healthy water conditions and serves as the foundation for sustainable aquaculture. The water quality monitoring products developed by JNC not only enhance wastewater management efficiency but also strengthen public safety and environmental protection. The Cloud Box, a solar-powered monitoring hub, provides power to sensors while simultaneously transmitting sensor data to the cloud. The Cloud Weather Station (CWS) is a multifunctional weather monitoring device capable of tracking eight meteorological parameters, including wind speed/direction, solar radiation, temperature, humidity, rainfall, and various gases. It supports USB data logging and cloud-based control. In addition to providing comprehensive environmental monitoring, the CWS can be used for factory pollution source assessments and features a warning alert system capable of issuing first-and second-level flood warnings. It is ideal for use in weather stations, bridges, airports, ships, smart buildings, and more.
