Radar breathing presence human body sensor bathroom human body sensing scheme

The radar breathing presence sensor is a smart bathroom body sensing solution. The radar breathing presence sensor is based on the millimeter wave Doppler radar system to realize human biological motion perception and human biological perception. Through the simultaneous perception technology of Doppler parameters of people's movement and physiological parameters of people, wireless perception of the state of people in a specific place can be realized.

Presence-sensing radar can limit the detection object to the human body (moving or stationary), and there is no interference from living objects in the environment; real-time monitoring and early warning can realize falling actions; realize the synchronous perception function of moving and stationary personnel; the output power is small, and it is not suitable for human body. Harmless; it is not affected by temperature, light, dust and other environments, it has high sensitivity and a wide range of applications.

The radar breathing presence sensor has scene recognition ability and can identify people/unmanned; it is suitable for harsh environments and is not affected by temperature, humidity, noise, airflow, dust, light, etc. Through the Pler radar signal processing system based on the millimeter-wave Doppler radar system, the human biological motion perception and the human respiration static perception are realized through the millimeter-wave Doppler radar system.

In response to the human body detection needs of the intelligent bathroom solution, the intelligent radar breathing presence human sensor was launched. Smart toilet is an innovative toilet operation management mode based on sensing technology, Internet of Things, cloud platform and big data application, aiming to provide people with higher quality, efficient, convenient and comfortable services. The service object is people, so the premise of true wisdom is the accurate perception of people. For example, the guidance function of the toilet needs to detect the use of the toilet through radar sensors, and then users and managers can understand the occupancy of the toilet or the mother and baby room, thereby improving the user experience of the user and the cleaning management of the toilet.

Smart toilets are suitable for various public places, such as high-speed service areas, gas stations, airports, railway stations, tourist attractions, hotels, shopping malls, schools, hospitals, office buildings, etc., including technical means such as use guidance, environmental monitoring, and equipment management.

The radar breathing presence human sensor includes minimalist sensor hardware and intelligent algorithm firmware, adopts radar measurement technology and advanced high-performance chip-specific signal processing technology, and is equipped with high-performance antenna and peripheral circuits. Load the default human sensing configuration, plug and play; certified by FCC and CE spectrum regulations; small and simple, easy to install, convenient for product design; accurate setting of sensing range, sensitivity and response time. Different from the traditional moving target detection technology, the human presence sensor radar uses intelligent chip technology and intelligent algorithms to determine whether the human body exists with high accuracy.

The Radar Breath Presence Human Sensor has a sensing module that enables accurate detection, whether static, micro-motion or motion. No privacy, sensitive issues, no lens design; long test distance, suitable for various installation heights; space areas of different sizes and shapes can be set freely. Can be hidden behind non-metallic materials such as wood or plastic ceilings and is not affected by environmental obstacles such as smoke, dirt blocking, low light, heat sources, etc.

In the era of intelligence, intelligent technology revolves around people, and the accuracy of human body sensing technology is particularly important. The smart toilet detects whether it is occupied by the human body, and the smart space automatically turns on the lights and automatically turns on the response control. The radar detection technology of the human body refers to the real-time monitoring of biological sensors and the use of the inherent physiological characteristics of the human body, such as the human respiratory rate, to accurately determine the existence state. According to the automatic induction of human breathing, it can judge whether someone is indoors, and realize non-perceptual intelligence.

With the development of the intelligent radar sensing market, the application field of the radar breathing presence sensor human body sensing technology will gradually expand. Adhere to the development of radar sensors with innovative technologies, and enrich AIOT application scenarios by applying non-contact radar sensor products. Provide accurate, reliable and sustainable radar products and technical solutions for intelligent end customers.
