THE first smart public toilet in Nanshan District, which makes full use of Internet and big data and can inform management of maintenance problems, such as water leaks and power outages, opened to the public Monday. The toilet is equipped with free Wi-Fi so that residents can receive real-time information on air quality, temperature and humidity, by scanning a QR code. By adopting facial recognition and fingerprint recognition technologies, the stall in the barrier-free toilet can automatically open and flush itself. (Zhang Yu) |
