Product features

Fall detection

  • Detects a person's fall when they are alone in a room
  • Detects all types of falls: fast falls, falls from bed, slow falls, controlled falls, falls in the shower, hidden falls (behind furniture, etc.)
  • Insensitive to different lighting conditions
  • Monitoring area: 4 x 5 m

Presence detection

  • Detects the presence of a person in a room
  • Not sensitive to lighting conditions
  • Monitoring area: 4 x 5 m

Presence detection in regions

  • Detecting the presence of a person in a defined zone within the room
  • Minimum zone size: 1 x 1 m in a 4 x 5 m room (for reliable detection)
  • Maximum number of regions: 6

Product overview

The Vayyar Care Sensor connects to the cloud or local server via WiFi. The data from the sensor is sent via HTTPS and MQTT messages. The OTA software upgrades can be done via HTTP. The sensor sends fall and presence events.

The Vayyar Care Sensor consists of an MCU HOST board and an RF board connected via a board-to-board (BtB) connector.

The RF board mainly consists of Vayyar VYYR7201 SOC and an array of 46 antennas for scanning the environment. The antennas are embedded in the PCB.
