 So, guys, your idea is already recorded in our last section, right? So, you don't need to completely go through your idea again. You can just briefly tell your idea, and then you can actually focus on whatever you want to do. Because you already have video of the idea. So, the idea for our application today is to let users inform whoever they want, where they are, and what kind of environment they are in without their interaction. They need not initiate any operation like something like Twitter where you are updating yourself, where you are in. You are checking in Facebook. So, something like that need not be required from the user's part. The amount of sensors we have, we can always get that data. So, that's what we are trying to achieve. We are using a couple of modules here. One is this small sensor device, which is a temperature reader, humidity, altitude, accelerometer, gyroscope, paradigm, etc. So, this one is going to give us some information that no smartphone can give, which is temperature, humidity, and altitude. And this information, we may use of it to identify what kind of environment the user is in. Another one is we have taken this Nexus device. This one actually uses Bluetooth low-energy, which is supported by this device only, and this device needs to be routed. So, which we have done today after coming here. So, to unlock the Bluetooth low-energy module. And another one is this apparatus, which we explain later anyway. So, this one is used for displaying a small tool-tip information for any user if necessary. Those who don't have access to the internet or anything, they can always look up for this. So, with the application... The first going on, we have to do the registration with the user name. And the threshold value is the value like the compass value. Like when you exceed this value, we will be started with communicating with the sensor device. It will show like, just go ahead and switch on the device now. So, I am going to register it. I have registered it, and it is showing this device. This is where I get my data. I have just updated my data right away. And in the server, you can see the updated data. There you have it. This is like the time stamp. This is the latest stamp. This is the time stamp. And the humidity value right now. And altitude is... And longitude and latitude, it's the DLF altitude and longitude. And we move ahead. Direction, pace and temperature. Direction, pace and temperature is 27 degrees. This is all life values. What you have just got from the meter. I have uploaded within a second to my server. And now this happens on activity. So, if there's an activity on the device, it's completely registered with the device when it is away from the device's threshold value. So, what we mean by threshold value is that each user has a preference. So, if he chooses that after something like 30 kilometers, he wants the device to switch on and try to send all the necessary data about his tracking or his travel mission along the way into the main database, he can do so. So, this is completely user's choice. But what we would actually extended this to children also where parents do want to have control over where the children are going or at least know if they are safe or not. So, these values would not make any sense if this device was used similarly. But since it would go through an android device into the service and then go to somewhere else with this device that we have, we would have meaningful sense of what this information actually means. So, why we had to dismantle this? Because it was part of our apparatus near the lamp house. But I just need a brief explanation of what this is. This is an Arduino board. It's along with a dedicated business chip that performs the Ethernet capability. So, what we have here is an IoT Internet of Things device. So, when the internet will be connected to this device, this device will have a polling mechanism where it will try to reach out to the server and try to find out what this particular device, like if somebody is having this device with them. So, all these necessary data, especially the distance from the start and the temperature. So, these are the two things that we feel that are important for a parent to know about a child or some tracker to know about a particular location. So, these are two things that are very important. So, these are the things that we don't get from a smart phone basically. Yes. And why we went for such a device was that because these are very, very low cost devices. So, when you have these devices, these devices can run for almost like five years with a single charge of DC up to two battery. And they are at throwaway prices. So, you don't need to have a costly phone to do this. You just need a normal Android phone and this tab to give you a very comprehensive data set about your typing machine. So, this is what we want to do. And this is an extension of the data that we have here and use it meaningfully for someone who cares about their person. So, this will be a code. This will be with the person who is traveling. So, we want to create that abstract. So, this is what we plan for this product. So, I think we can also say this product will help. Yeah. So, I've been about connected with this LED, multi-color LED here. Full color LED basically. And what we have is, every time there is an update to the server. So, this Arduino board is going to pull the server every time. And it will get the distance from the start and location, current location. By that, we can actually calculate how far he is from this central location, which will be marked the first time he starts using it. So, from that central location, if the threshold value is say 30 kilometers, if he starts moving outside, so then until 30 kilometers, this light will glow green. And if he starts moving outside, it slowly starts moving to orange. So, the calculation that we have right now is, if he reaches 60, probably what I'm saying is, if he reaches 200 percent of the threshold, it turns non-clear, which means he's way outside the moment. So, that's the logic that we have right now. What we were planning was have some sort of an external display that will take this distance and take the location, plot it on a map view. So, this may just be fine. Do you have any questions? So, what other sensors do you think will add value to this? Right. So, one thing that we haven't used yet is gyroscope. So, you saw something like, you saw something like direction-facing, right? So, direction-facing is something, right now we've calculated based on, we've tried to calculate based on what the data is given by the device. We weren't able to, so right now it's already a smartphone, from the smartphone, the tablet, but we weren't able to complete it. So, right now it shows not all the time. But ideally, using the magnetometer and the gyroscope, by using a sense of fusion, we should be able to identify the value, which direction is moving. So, any person who is looking at that information will know which direction he's going. So, he'll know whether he's coming in or he's going out, because this update is going to be every, not frequently. Any other questions? No. Okay. So, who wants to go next?
