 Hi there, let's talk about turning your smartphone into a mobile air quality monitor. ST and our partner Mobile Physics have created a system using a standard direct time of flight module that can measure the level of pollution in the air. The result can help you to take action to improve it, maybe open or close the window or perhaps turn on the cooking extractor fan or air purifier in your home. Using the output ranging data from our VL53L8, a 64 zone time of flight module, the innovative software from Mobile Physics can measure the level of PM2.5 particles in the air. PM2.5 material can potentially be damaging to your wellbeing. The small 2.5 micron diameter particles can enter the bloodstream and cause long term health damage, so it's vital to understand your exposure level. This new feature for the VL53L8 works alongside the normal camera focus support, increasing the value for money for our customers. Now unlike traditional air quality monitors, our system has no moving parts and is also tiny so it's perfect to use in a smartphone or other products like smart TVs, smart speakers or even as a personalised smoke detector for extra security while you are sleeping. Now, let's have a look at it working. The VL53L8 is inside this chamber, there it is at the bottom, so that we can easily increase or decrease the level of pollution. We begin with clean air and you can see the system has given us a green light, but as we start to increase the level of pollution we first get a yellow warning to show the pollution level is rising and then finally a red light to say you need to do something, the air quality is not so good anymore. We really think this new use case can bring amazing benefits to every smartphone user and be used in products throughout your home too that will really help you make smart choices to improve the quality of air that you breathe.
