king has led tributes to the armed forces on remembrance sunday at a service at the cenotaph in london. thousands of veterans and army personneljoined the public in a two minute silence at 11am. it isi:30pm. now it is 1:30pm. now on bbc news, click. this week, paul has been tackling blazes in germany. question, how do you attract the right fish to your net? we will shine the light on a colourful solution. oh, look at that, pennies from heaven. and. take a feel. you can feel the texture. it s really soft. yeah - that s not what you need from a crisp. we ll find out why it s crunch time for al. it is an inferno and it s leaving little in its wake. we ve seen wildfires raging across many countries over the summer months. the hot, dry conditions exacerbated by climate change are making them more frequent and more intense. and it can often be a real struggle to bring them under control. high tech solutions are changing how we tackle them, whether it s drones dousing the fires or
been tackling blazes in germany. question, how do you attract the right fish to your net? we will shine the light on a colourful solution. oh, look at that, pennies from heaven. and. take a feel. you can feel the texture. it s really soft. yeah. that s not what you need from a crisp. we ll find out why it s crunch time for al. it is an inferno and it s leaving little in its wake. we ve seen wildfires raging across many countries over the summer months. the hot, dry conditions exacerbated by climate change are making them more frequent and more intense. and it can often be a real struggle to bring them under control. high tech solutions are changing how we tackle them, whether it s drones dousing the fires or satellites predicting their spread. and paul has been to a forest near berlin to find out how one company is trying to prevent forest fires from taking hold in the first place. it s conventional wisdom that the earlier forest fire can be stopped the better, but often a fi
to prevent forest fires from taking hold in the first place. it s conventional wisdom that the earlier forest fire can be stopped the better, but often a fire can already be well established before it is noticed, making it harder to put out. but one company in germany believes it has a possible solution by using internet of things, sensors and alto understand what forest fires smell like. the basic function is like an electronic nose that we put into the forest and it can actually smell a fire. we can detect fires during the smoldering phase. so a few minutes after someone has thrown a cigarette, we should be able to ring the alarm bells. every forest fire has a unique aroma based on what surface material is around. i love that smell. yes. their forest ecology expert, dr. juergen mueller, collects these samples from around the world and then burns them to generate the data to train the ai on what an actual fire in a specific location may smell like. ok, now, we closed the cha
the sensors every 100 meters in more remote areas and 15 meters near well walked paths. so it looks like quite a lot of smoke coming off there. would that be enough already for your sensors to to be able to detect? that is enough for our sensors. so this smoke needs to reach the sensors, that means if the sensor is close to the smoke, for example, on this tree, then you have it within seconds. but it s notjust the eye and the sensors that are innovative. there s another problem that needed solving. we re here in a forest, in a rural area where i imagine there isn t much mobile signal. how do you get the data from the sensors out to where it needs to go to? because mainly there is no internal telecommunication infrastructure in the forest, we bring our own telecommunication infrastructure to the forest. so this is the mesh gate. oh, wow. okay. yeah. these mesh gateways needs to hear over the air. if one of these sensors in the forest has an alarm or a signal and so on, and the
