EnOcean Sensors Make the Library Smarter

September 15, 2025

Tongji University in Shanghai is one of China’s leading universities, with four campuses across the city. During the summer break, the university renovated the library at its Jiading Campus, including a major upgrade to the air conditioning system.

To enhance energy efficiency and enable smart control, the university needed to add sensors to each floor—without the complexity of wiring. That’s why they chose EnOcean’s ultra-low-power wireless communication technology.

Nanjing WinShine provided the EnOcean-based sensors used in the project. The university selected temperature & humidity sensors and CO₂ sensors from WinShine. These devices are powered by indoor light through energy harvesting. The temperature & humidity sensors were flexibly installed on bookshelves in the stacks to monitor environmental conditions around the stored materials. In the reading areas, the CO₂ sensors—integrating temperature, humidity, and CO₂ measurement—help track air quality in real time.

With this data, administrators can fine-tune the air conditioning and ventilation systems and manage occupancy levels. The result: a more comfortable and safer study environment for students, while reducing energy use and cutting CO₂ emissions.

The library restrooms were also upgraded with smart features, including stall occupancy guidance, environmental monitoring, automated disinfection, and intelligent control of electrical systems. These enhancements improve convenience for users and support demand-driven cleaning and maintenance.

Easy Installation, Maximum Flexibility

Before installation, WinShine pre-configured all sensors and gateways according to the layout plans. On-site deployment required only mounting the devices—no wiring needed. This eliminated nearly 10,000 meters of cabling and significantly shortened installation time. The flexibility of the wireless setup also allows for easy adjustments and expansions in the future.
