Selection and Support
Is measuring humidity during “hui nan tian” conditions accurate with a wireless temperature and humidity sensor? The key lies in these few factors. Whether a wireless temperature and humidity sensor delivers accurate readings during “hui nan tian” depends crucially on whether its performance specifications can reliably handle high-humidity environments. Choosing a device that offers a wide measurement range of 0–100% RH, high accuracy (e.g., ±1.5% RH or better), robust IP67‑level protection, and industrial‑grade reliability is essential to ensure precise and dependable data—even under the challenging conditions typical of “hui nan tian” and other harsh, complex settings.

How does a smart door sensor provide silent protection for doors and windows?
Smart door/window sensors—these compact devices attached to doors and windows—integrate magnetic induction technology, LoRa low‑power wide‑area communication, and an IoT cloud platform to create an invisible yet exceptionally vigilant security barrier. Operating with microamp‑level power consumption, they silently monitor conditions and deliver precise alerts within milliseconds, translating the physical state of doors and windows into remotely accessible digital signals. They provide round‑the‑clock, intelligent, and highly reliable security for doors and windows in a wide range of environments.

Smart Hospital Restroom Human Fall Detection Solution
To prevent such tragedies from recurring, our company has designed and developed a bathroom‑based patient‑fall detection solution, using hospital restrooms as a case study. Due to privacy concerns, cameras cannot be installed in hospital restrooms. In response to the issue of patient falls in these settings, we have created a patient‑fall alarm system. The system comprises three components: sensors, wireless transmission, and an alarm terminal. The sensor suite includes an emergency button and a 60 GHz millimeter‑wave radar sensor; the 60 GHz radar is mounted at the ceiling of the restroom and incorporates an integrated fall‑detection algorithm. When a fall is detected, it triggers an alarm signal. The emergency button is positioned beside the toilet stall, allowing patients to activate an alarm in urgent situations. For wireless transmission, the system supports three options: LoRa, LoRaWAN, and CAT‑1.
