 Hello, my name is Ritu Padhyay and today I want to talk to you about how you can use our time of flight for liquid level monitoring. Before I get into the details, let me show you some of the applications where liquid level monitoring could be enabled. For instance, wouldn't you want to know what the water level is before diving into the pool? Or, measuring the level of wine in your wine barrel. Applications could also include measuring coffee in a coffee cup to avoid overspell. Now, why should you consider using time of flight for liquid level monitoring? Number one, there are no moving parts, meaning a more robust solution. Number two, unlike traditional monitors, it has a high accuracy so you can rely on the results you get. Number three, it is a low complexity part that can be used on a large variety of liquids and it is food safe. Here I'm showing you a quick work and example of liquid level monitoring using our time of flight. In this video, the sensor can record the water level changes in real time and very accurately. To help interpret the results, on the right hand side you can see a still image for a quick accuracy check. Now, let's get into the technology of time of flight. The basic principle of our time of flight is that we're shooting photons and we're measuring the time it takes for those photons to hit a target and bounce back. And since we know the speed of light with a very simple formula, we can didn't mind the distance of an object. Sometimes liquid level detection can be a challenge for optical sensors. These challenges are usually caused by either liquids refractive index or sometimes liquid absorbs the photons or even turbulences of the liquid. However, ST's new time of flight solution sensors has the ability to overcome these challenges. For this demo, we used our VL53L5 time of flight. It can produce up to 64 zones and each zone gives you a signal strength and distance measurement. It has a full Class 1 safety wixel and advanced optics. To summarize, ST provides a best-in-class time of flight for liquid level measurement. It is fast, most accurate device for distance ranging. ST also offers a complete evaluation kit, design guidelines, and liquid monitoring code for fast and efficient integration. To achieve the use cases you saw earlier, we have a list of EVKs and software available on our website for free. So please contact your local sales to order one now. Thank you.
