 Hello, my name is John and today I will describe you one of four time-of-flight demonstrations. Nowadays there's a rising trend where companies dealing with retails and logistics have significant amount of money by improving their automatic stock management systems. Whether it be for keeping their shelves full or stocking their warehouses, they are leveraging IoT for continued stock monitoring. In this video I will be showing you a static and a level wireless content monitoring system by using a device named BlueTide that contains the L53L1X plus Bluetooth low-energy connectivity. All this piloted by an Android application. Let's jump straight to the demonstration and see what it does. Here you have four shelves with pushers that we can empty or even fill at will. You can see on the result on this tablet where levels are continuously reported. We can easily imagine how such information will be used by retail manager to avoid empty shelves. We can define this as asset detection or content load monitoring. So we need to monitor shelves' stock levels. A good way to do it is to report distance. Here from the pusher to background. The key points for us then is to be able to measure the distance regardless of the kind of the product we have. To do this, our VL53L1X is particularly effective. Time of flight technology is independent from target and color size. This will ensure a constant accuracy no matter what kind of environment we have. Another point remains tricky. We have to adapt to different product sizes. Here we can see that we have product of different widths. VL53L1X enables us to set the region of interest. That means adapting the field of view depending on the need. Here in this example between a USB stick and the other wireless items. Let's look more in detail at a different component of the demonstration. Here you can see how tiny it is. Here we have a blue tile which contains amongst other sensors or VL53L1X. The VL53L1X is an only one module. It manages both emission and reception. That makes it easy to integrate. Note that the blue tile also contains a microphone, a humidity and temperature sensor, a magnetometer, an accelerometer, a gyroscope and an ambient pressure sensor. For this 3D-made ST environment you can download many different resources from st.com slash VL53L1X. That includes technical docs, GUI software, software example, and you can even order nuclear kits from the website. For the blue tile development platform you can find everything you need here.
