We have developed a simple demo system for detecting presence in a room using Acconeer AB's 60GHz radar.
This technology can be applied to human detection in environments where it is difficult to use cameras due to concerns about privacy violations.
Simple demo system for detecting presence in a room using millimeter-wave radar
The simple presence detection demo system developed by Nexty Electronics detects people using multiple Aconia 60GHz PCR radars installed in a room.
This detection data is transmitted to the gateway via BLE to determine the presence or absence of the person in the room.
Furthermore, room occupancy status can be uploaded to the cloud and notified to a smartphone application, allowing you to know the occupancy status in real time.
Features
The radar is ultra-compact, low power consumption, and highly accurate
Aconia's 60GHz radar has ANTENNAS built into the surface of the chip, and although it is ultra-compact at 5.5mm x 5.2mm x 0.88mm, it is capable of measuring in millimeters within a range of about 2m.
In addition, the radar system uses Aconia's unique pulse coherent radar system, which achieves both high accuracy and low power consumption.
Achieve presence detection with a simple system
The data acquired by the radar is sent to the gateway via the BLE microcontroller as an advertising signal at 1-second intervals, and the gateway then aggregates the data from multiple radars and sends it to the cloud (AWS) via the MQTT protocol.
Data processed in the cloud notifies users of their presence via LINE, a familiar smartphone app.
Use Cases
Presence detection in conference rooms and private rooms
When it is not possible to tell from the outside whether there is someone in a closed conference room or private room, radar can be used instead of a camera to detect people while respecting privacy.
Preventing children from being left behind on buses, etc.
By using radar to detect people in each seat on the bus, it is expected that this will also help prevent children from being left behind, which is a social issue.
