 Hi, my name's John and I'd like to tell you about a time of flight sensor from ST Microelectronics. This tiny little chip has three components. It's got a laser emitter that shoots out a little flood of light. It's got a receiver to get those photons back and a little CPU to figure out how long those photons took to get to the target to bounce off and to come back. Do a little math and I can give you the distance. It's a pretty good demo here where I can tell how far away my hand is right here or how far away my body is right here. And it's a tiny little sensor right there. You can also use it in short distance application to turn on a faucet. It turns blue because I didn't want to get water all over the countertop. But the trick to this is it's tiny, it's inexpensive, a couple of bucks, maybe a little more, and very small. It's I squared C, easy to hook up to a computer. We give you all the software you need and it just works. One of the things I should mention is it's pretty low power, perfect for battery applications of cell phones and faucets and other things that aren't plugged into the main power supply. It's a VL53L0, but you don't have to remember that. Go to the ST Microelectronics website and search for time of flight. You'll get right to it and tell you everything you need to know. Lots of information on that site including web, including data sheets and everything else you need.
