QPS2221 developedby Insightica is a radar module that can sense the proximity of human body to open the toilet lid and toilet seat without any contact, which is specially designed for bathroom.
When the user approaches the toilet, the human body induction triggers the toilet to automatically flip the lid, waving the hand to flip the seat, and automatically closing the lid when the pearson leaves. The company's independently invented energy accumulation algorithm can greatly enhance the sensitivity and accuracy of the radar, solving the current problems of intelligent toilet gesture controls such as no response to the waving hand frequently, needs of leaning down closely, false triggering.
- Can achieve accurate range monitoring with the positive radar response function within 40cm and no response outside 60cm, solving the false triggers generated when people pass by.
- Can be adapted to a variety of structures with high integration
- Achieve accurate judgment while filtering invalid behaviors based on FM continuous wave radar technology and uniquel energy accumulation algorithm.
- Detecting the user's movement speed, direction and relative distance to pre-judge the user's intention.
- Intelligent opening and closing control of the toilet seat through hand waving gestures.
- Unaffected by temperature, humidity, noise, airflow, dust, Light, etc., suitable for harsh environments
- Low output power, no harm to human body
- Dynamic data sensing only, no privacy violation.
- All-weather and all-day application.
Smart Toilets
This radar scans the indoor object activities at a frequency of 50ms once, and remotely senses the subtle movements of people within 10 meters through millimeter waves to determine whether there is anyone in the monitoring area. In the monitoring area, the user's intention can be pre-judged by sensing the user's movement speed, direction and relative distance. With the radar, the toilet is activated from the dormant power-saving mode when someone enters, and according to the relative distance, the toilet can intelligently judge whether the user is likely to use the toilet, then the cover is opened in advance, the toilet ring is preheated and the night light is turned on, etc. It realizes the functions of smart toilet ring heating, smart night light and smart flipping lid, which greatly improves the using experience.
The radar is compatible with diverse structures, can achieve accurate range monitoring with the positive radar response function within 40cm and no response outside 60cm, solving the false triggers generated when people pass by, and can flip the seat by waving hands, being able to wake up the device in time to realize contactless experience.
