 Hi, my name is John and we are here at CES 2024, and I want to tell you about a whole new application for the VL53L8 time of flight sensor. We work with this really interesting company, Mobile Physics, and what they have done is taken the raw data from our time of flight sensor and figure out a way to find particles in the air. In this chamber I've got a layer of smoke down here. You can't even see it, it's so fine and so small. And I'm going to turn on this fan right there, where my buddy Tomah is going to turn on the fan. And it's going to lift that smoke into the field of view. And right here the good air quality sensing will start to go bad. Unfortunately it's not instantaneous, but that fan's got to get going. And if it doesn't get bad enough, we're going to add a little flash of smoke right there. Did you see it? Look at that. Way up there. So smoke, so fine, you can't even see it, yet the sensor can. It's really an interesting way to use a time of flight sensor. It's easy to buy too. ST builds the hardware, we add the software from Mobile Physics, you buy it as one part number, and you're all set. Just hook it up. Now, over time, if you just wait a little bit for those particles of smoke to filter down and for my little vacuum cleaner to suck some of them out, you can see that the air quality gets better and better and better. Unfortunately you're waiting for gravity to take over in things, so it's not fast, but you really get a good indication of how many particles were detected just above that sensor. And all of this is brought to you by ST. And this guy from Mobile Physics, but remember, with ST, technology starts with you.
