occupancy DETECTION

A low cost, low power, easy to install and smart radar sensor

COVID-19: A WAYV OF NEED FOR OCCUPANCY DETECTION

In response to the demand and new guidelines for social distancing monitoring, Ainstein has launched an intelligent human presence sensing radar. Leveraging our WAYV AIR 60GHz millimeter wave radar, we have solved the downfalls of existing traditional sensing technologies such as PIR human motion sensors.

Various problems and shortcomings exist in ranging sensors and single-point ranging laser sensors.

The smart sensor system is an innovative model for human motion detection. It works perfectly for restroom occupancy and management for maintenance.

Leveraging our sensor technology, the Internet of Things, cloud platforms, and big data applications, this sensor provides people with better, more efficient, convenient and comfortable services.

Occupancy management and detection include a variety of technical means such as:

Space Utilization
Maintenance alerts
Equipment management
Energy consumption management
Cloud integrated management

THE LIMITATIONS OF EXISTING TECHNOLOGY

The PIR infrared human motion sensor is cheap, but the disadvantage is that it cannot detect stationary people. When the people in the room have limited motion or do not move, it will cause detection errors. In addition, large changes to an air conditioner, ventilation fan, and temperature difference between indoor and outdoor rooms can cause false alarms.

Infrared ranging sensors are generally installed above the toilet seat and determine whether someone is occupied by the change of ranging. The disadvantage of this scheme is that the range is short, the accuracy is low, and the recognition of objects is not accurate. This is why it is prone to false alarms and the installation height is limited to 2 meters.

The single-point ranging laser sensor is a relatively novel sensing method, similar to the infrared ranging sensor. It is also installed directly above the toilet to detect the change in the distance of the obstacle to determine whether it is occupied. The problem of the single-point ranging laser sensor is that the detection range is small and it can only cover the area of the 3-5cm radius circle directly below the sensor. Therefore, when personnel deviates from the outside, the detection will be invalid. In addition, this will also bring challenges to the actual project layout, because there are usually other facilities such as lights, exhaust fans, etc. above the toilet, resulting in more requirements and restrictions in actual construction.

USE CASE: BATHROOM OCCUPANCY MANAGEMENT

Ainstein’s sensing solutions are not affected by lighting conditions and are extremely robust to adverse conditions such as dust and smoke. This makes them the optimal solution for indoor and outdoor restroom operations.

The WAYV Air has already been successfully applied to a number of smart bathroom project solutions to achieve toilet seat detection and human flow statistics. Our customers are extremely pleased over the WAYV Air’s accuracy, low cost, low power and easy installation.

In particular, our customers are most pleased with the detection accuracy. This is true whether the person/ object is stationary, micro-moving or moving. The WAYV Air can achieve accurate detection in every case.

THE WAYV Air:

A SMART SENSOR RADAR THAT POWERS IoT PROJECTS

WAYV Air is a short-range mmWave IoT Sensor. Further it is an industry leading 60GHz radar module designed specifically to collect and provide data about moving objects within a targeted area. It’s the perfect building block to develop innovative new applications for building automation, retail management, facility monitoring, and more!

The accurate and real-time perception of objects via robust sensors is the key to enabling occupancy tracking and management. One of the benefits of radar sensing is that it works effectively in all environments (e.g. smoke) unlike other perception technologies such as camera, ultrasonic, and LiDAR.

Ainstein’s WAVY radars use proprietary antenna arrays, advanced signal processing and target recognition.

OCCUPANCY DETECTION: 6 ADVANTAGES OF RADAR SENSORS

BUILDING AUTOMATION

Another major benefit of radar technology is that sensors enable real-time signal processing in advanced building automation use cases such as management of HVAC, smart security lighting and fire safety systems. mmWave sensors use onboard processing to reduce false detection by ignoring signatures of static objects that are not of concern, such as chairs and desks, and dynamic objects such as fans.

Radar sensors can count the number of people in a room and determine where they are located. This data can be used to adjust the HVAC and lighting systems automatically to ensure the optimal balance of comfort and cost savings. This also removes interaction with high touchpoint areas, like light switches and thermostats, to further reduce the risk of transmission. In another example, sensors can send automated alerts to service bathrooms and lounge areas after a set number of visits. In our new normal, this is a helpful way to deliver a high level of consistency and cleanliness, without invading or disrupting the tenant or guest experience.

EXPERIENCE PRESERVATION

The visitor/tenant experience is drastically improved by the implementation of radar technology. Because radar sensors facilitate social distancing through proper traffic flow planning, visitor/tenants are provided with the first level of safety assurance before they even walk through the entrance. The data collected by sensors provides powerful insights to more effectively and efficiently remove friction points in high traffic areas, providing extraordinary protections to anyone entering or exiting.

Because radar sensors do not use cameras or optical lenses, they are also suitable for privacy-conscience applications such as restrooms—they can even be installed behind the ceiling or wall, to improve aesthetics and further reduce privacy concerns.

SMART SENSORS SERVE PEOPLE

Smart sensors serve people. Being “smart” is having the precise perception of people. For example, a toilet usage guidance function needs to be used by smart sensors to detect the passenger flow and the occupancy of the toilet seat. Through the interactive display or APP method, our technology lets users and managers understand the occupancy of the room. This improves the experience of the users and the cleaning management of the room.

New generation 60GHz technology

Relying on the technical advantages and accumulation of research and development in the field of radar sensor research, Ainstein has launched an intelligent human presence sensor based on the WAYV AIR 60GHz millimeter wave radar, which solves the many shortcomings of traditional sensing technology often used in current smart toilet solutions.

CROWD DENSITY MANAGEMENT

Social distancing is part of our new normal and buildings now have a responsibility to protect both staff and visitors by monitoring and maintaining occupancy to prevent a second wave of the virus. Radar sensors ensure optimal social distancing throughout the building by enabling accurate counts of people entering and leaving a space (such as a restroom) and providing a reliable understanding of the frequently changing hotel environment.

While cameras are good at recording what’s happening, radar provides data points such as presence information, the number of people in a given area, where people are located within the sensor field-of-view, as well as the distance between people. This data can be aggregated and analyzed to gain insights on crowd density and visitor traffic flow.

By analyzing this data, operations managers can anticipate and mitigate transmission risks before they happen. By knowing the real-time occupancy and utilization of gyms, conference rooms and other common amenity spaces, staff can manage occupancy to maintain social distancing, adjust cleaning services, food and beverage, and staffing to match real-time attendance.

LOW-COST, LOW-POWER WITH HIGH-RESULT

Low cost Radar or Microwave normally fails in similar restroom occupancy scenarios because the person using the restroom cabin would stay relatively stationary for a couple of minutes. Our WAYV Air team developed a proprietary algorithm to address and solve this specific issue.
