 Hello everyone my name is Chris field application engineer ST and I help support our mem sensors. So I'm here at CES 2024 to introduce to you our presence detection solution using ST's sensor solutions. So in terms of presence detection and human occupancy there's several factors that you want to consider. So one of the most important aspects is that the sensing system needs to accurate and reliable in order to give you the correct output in terms of the accuracy and also where the user may be. Another aspect that you need to consider is that the sensing system may need to be a low power system in cases that you need to have the sensing system operate on the battery continuously. Lastly another important aspect to consider is that you may want to enable additional feature on top of the typing presence. So one of which could be determining the location of a person and how many people they are inside the room. And the other aspect could be to enable touchless gesture control. So I'm here to show you both of these solutions with two of our demos. So I'll pass the ball to Salma to show our first demo here. Thank you Chris. So I'm showcasing the first demo here which is a ceiling mounted room occupancy sensor node. So what we are showing here is we are utilizing our T-MOS infrared sensor which is detecting a user inside a vicinity or a room as it is a very low power sensor. When it detects a person it wakes up the device and then we use the time of flight to use better sophisticated features like room occupancy analytics. So now I will show you the detection zone of the T-MOS which is the dark blue circle and as I step in you can see that on the visualization we can see that there is someone inside the room. The light blue square is the detection zone for the time of flight. As I step in now we can see that it says someone is in the room and it is detected by both the T-MOS infrared sensor and the time of flight sensor. Now if I step on the left side of the zone it says there is someone in the field of view on the left side of the room. Now if I can ask John to come in and stand on the right side. Now it says that both people are detected inside the room on both sides. All right so basically what we are trying to show in this demo is that we can use the low power T-MOS infrared sensor as an instigator to wake up the device so we can optimize energy efficiency and we're using time of flight sensor to enable sophisticated features like the room occupancy analytics and now I'll pass the ball to John for the second demo. Thanks Salman. Hi I'm John Hyslop an applications engineer at SC Mike Electronics. I'd like to show you the second part of our presence detection demo here. It's basically a wall mount thermostat. First I'll approach the T-MOS will sense my presence and turn on the light. Now I'll approach the podium. The time of flight will detect that I want to interact with the device by the proximity detection and then I can actually interact with the device in a touchless manner using gesture recognition such as left swipe or right swipe. At the heart of these demos is the new STFL P-Detect 1 board. It consists of the STHS 34 PF 80 T-MOS PIR sensor as well as the VL 53 L8 CX direct time of flight multi-zone sensor and the VD 6283 ambient light sensor. We also have another add-on board for this demo from sensorian which contains a digital humidity and temperature sensor and a volatile organic compound sensor used to display on the thermostat the environmental variables. The STFL P-Detect 1 goes along with our STWIN box development kit which contains nine industrial sensors. You can use the combination of these boards easily to prototype very quickly and collect all kinds of data for your application. Thanks for your time.
