FS01 - Work environment and thermal comfort monitoring

The ASSC is worn by the users like a wearable. It captures personal exposure to light, sound, temperature, and air quality, as well as information regarding physical activity, including sitting and standing behaviour. This set of sensing capabilities contributes to providing insights into personalized vitality: the amount of physical activity (or lack thereof), the relation between exposures in the office environment and aspects related to mental and physical wellbeing. One other aspect that would be interesting is indoor localization and authentication.

FS02 - Parking lot occupancy monitoring

One or more ASSCs are installed in an indoors or outdoors parking area. After the initial ASSC configuration by the system administrator, each card provides information about the occupancy status of a parking spot. Potential vehicles are detected using the light sensor in combination with the magnetic and imaging sensor. The light intensity will be reduced if the card is placed in front of the incoming vehicle. Furthermore, the metallic frame of the car will affect the magnetic field near the sensor. When a change in light intensity is detected, data from the magnetic sensor will be used in order to confirm or not the presence of a vehicle. Then, the imaging sensor will be used for vehicle verification using the edge intelligence module. Subsequently, the ASSC will transmit the collected data to the parking's control system via LoRa wireless communication. Informative displays will show the number of free parking spots in the car park.

FS03 - Crowd counting for social distancing

The ASSC is installed in an indoor room and is placed on the ceiling. After the initial ASSC configuration by the system administrator, it can be provided the total number of people who occupy a room. A low power and low memory object detection algorithm is used in order to detect each person. Subsequently, the ASSC will transmit the collected data to the user via BLE and LoRa wireless communication.
