CES 2024 - ST Microelectronics Presentation on Presence Detection Solutions

Presenter: Chris Field, Field Application Engineer

Introduction

• Presented by Chris Field, Field Application Engineer at ST Microelectronics
• Focus on presence detection solutions using ST's sensor technology

Key Factors in Presence Detection and Human Occupancy

1. Accuracy and Reliability
   • The system must be precise to provide correct outputs regarding user location.
2. Low Power Consumption
   • Essential for battery-operated systems to function continuously.
3. Additional Features
   • Location determination and counting the number of people in a room
   • Touchless gesture control

Demo 1: Ceiling Mounted Room Occupancy Sensor Node

• Presented by Salman: Showcasing a ceiling-mounted occupancy sensor
• Technology Used: TEOS Infrared (IR) Sensor
  • Low power, detects user's presence to wake up the device
  • Uses Time of Flight (ToF) for advanced features like room occupancy analytics
• Detection Zones:
  • TEOS IR Sensor: Dark blue circle
  • Time of Flight: Light blue square
• Features:
  • Room enters detection zones, triggering visual indication
  • Ability to differentiate the location of individuals within the room

Demo 2: Wall Mount Thermostat

• Presented by John Heisel, Applications Engineer
• Key Components:
  • ST's OFal P Detect One Board with multiple sensors:
    • STS 34 PF80 TEOS P sensor
    • V53 LHcx Direct Time of Flight Multizone Sensor
    • VD 6283 Ambient Light Sensor
• Functions:
  • Presence detection to turn on the light
  • Proximity detection for interaction
  • Touchless gesture recognition: left swipe, right swipe
• Add-on Board: Contains humidity, temperature, and VOC sensors to display environmental variables
• ST WIN Box Development Kit: Contains 9 industrial sensors for rapid prototyping and data collection
