What are the advantages of using millimeter-wave radar in third‑party restrooms?

With the continuous advancement of technology, intelligent sensing technologies are being increasingly applied across various fields. In public spaces—particularly in specialized environments such as third‑party restrooms—the demand for safety, convenience, and privacy protection is steadily growing. As an advanced sensing technology, millimeter‑wave radar, with its unique advantages, holds significant potential for use in third‑party restrooms. This paper aims to explore the feasibility of deploying millimeter‑wave radar in such settings and to analyze the benefits it can deliver.

Application of Millimeter-Wave Radar Fall Sensors in the Third Restroom

In the third‑party restroom, millimeter‑wave radar can be used to monitor pedestrian traffic in real time and assess the level of congestion. When the number of people inside exceeds a threshold, the system automatically triggers an alert, prompting staff to manage the flow and ensure user safety. Additionally, millimeter‑wave radar–based fall sensors can detect abnormal conditions, such as prolonged periods of inactivity or sudden surges in occupancy, enabling timely response measures.

What distinguishes the accuracy of a PT100? What types of probes can it be connected to?

The accuracy class of a PT100 temperature sensor affects the precision and reliability of its industrial applications, with classifications such as Classes A, B, and C, each suited to different accuracy requirements. Accuracy is influenced by material purity, manufacturing processes, and environmental factors; therefore, selection should take into account the measurement range, response time, and other relevant parameters.

Intelligent Campus Smoking-Prohibition Solution for Students

Recently, primary and secondary school students, in pursuit of the so‑called “cigarette‑card trend,” have even begun experimenting with smoking and using cigarettes as bargaining chips—actions that carry far‑reaching consequences. Smoking among minors not only harms their respiratory systems and accelerates the decline of cardiopulmonary function but can also lead to a range of chronic diseases, severely impacting their growth and development. Worse still, such harmful behavior can easily foster negative social habits, distort values, and negatively affect academic performance and future life prospects. All sectors of society must take this issue seriously, strengthen education and guidance, and create a healthy, smoke‑free environment to protect young people from the dangers of tobacco. To effectively monitor smoking in student dormitories and on campus, intelligent anti‑smoking solutions have emerged. We will introduce an intelligent smoking‑detection system for student dormitories and campuses, based on cigarette‑detection sensors, LoRa communication gateways, and alarm control panels. This solution aims to enhance the efficiency of dormitory and campus management while fostering a conducive learning and living environment.

Do millimeter-wave radars emit radiation? At what power level do millimeter-wave radars become harmful to the human body?

Millimeter-wave radar does indeed emit radio waves—also known as radar waves or electromagnetic waves—during operation, and these waves constitute non‑ionizing radiation. While millimeter-wave radar emits non‑ionizing radiation, the associated health risks are extremely low. Under normal operating conditions, millimeter-wave radar can be considered safe. Nevertheless, it is still important to remain aware of potential safety concerns and to implement appropriate protective measures.
