To add an extra layer of control I use the HTML5 storage to detect if it is using mobile storage or desktop storage. If the browser does not support storage I have an array of mobile browser names and I compare the user agent with the browsers in the array. Check out this post , it gives a really nice code snippet for what to do when touch devices are detected or what to do if touchstart event is called:. Yes, it is browser-sniffing, but sometimes that is exactly what you need.
Taken from What's the best way to detect a 'touch screen' device using JavaScript? As per Mozilla documentation string Mobi is recommended. But, some of the old tablets doesn't return true if only Mobi is used, hence we should use Tablet string too.
Similarly, for being on the safe side iPad and iPhone strings could also be used to check the device type. I know this old question and there is a lot of answer but I think this function is simple and will help for detect all mobile, Tablet and computer browser it work like a charm. If you goto any browser and if you try to get navigator. Based on the result I'll be doing required changes.

Provide a mobile URL specifically for mobile devices.
This is how most major sites handle mobile devices. See m. It is provides cross-browser DOM traversal and manipulation, simple animation and ajax between browsers, and creates a skeleton framework for plugins to build upon. Please be aware of jQuery's limitations before asking specifically for a jQuery solution. User agents are constantly moving targets, everyone reading this post should be very wary of user agent sniffing — Rob.
What's a 'mobile' device? Is it a device that supports touch including Chrome Pixels and Windows 8 laptops with mice? Is it a device with a small screen what about retina iPads? Is it a device with a slow CPU? Or a device with a slow internet connection? Depending on what you want to do the answer to this question will vary. To target screen resolution or touch is easy. If you want to serve up smaller content or less intensive JS for some devices, then there's no silver bullet.
Test for window. My 2 cents. Cole"Cole9"Johnson My point exactly. But none of these are perfect assumptions. I believe that considering these individually will result in a better product than designing for some vague concept of 'mobile'. Hence me posing that question to the OP. Show 12 more comments.

Twitter LinkedIn. As you can see in these pictures, there are a few possible layouts, but all have a few things in common. If you are attaching an LED to any of the pins the longer of the two LED legs is the one that connects to the pin , the other side must connect to ground in order to function.
If at any time you look at your LED lit up and immediately think, "Wow, that's really bright," you should probably add a resistor. Once you have the LED wired, you can test the connections by adding a wire to the pin marked "3. If it lights up, everything is connected and you're ready to begin your test. To test our ability to detect a device with a MAC address added to our tracking list, we can do a few things to stimulate a burst of packets.
On an Android phone, this is often as simple as activating the screen of the phone while the Wi-Fi is turned on. On an iPhone, it might take a little more interaction. An iPhone automatically connecting to a network that it has connected to before, or being presented with a swarm of fake networks like in our beacon swarming attack , will also reveal its real MAC address.
Both of these will cause the kind of signals our Friend Detector will react to. In practice, a way you can take advantage of this is to set up a network you know the target's phone will react to in proximity to the Friend Detector and simply wait for the device to decloak itself on the same channel.
The addition of an "active" decloaking element greatly increases the effectiveness of the detector, but that is a more advanced design than we will cover today. After turning on your Wi-Fi and connecting to a nearby Wi-Fi network if necessary, you should see the LED light up when one of the devices on the list is detected. When this happens, you've successfully created a MAC address sniffer! You can make this project even more useful by adding a directional antenna , allowing you to start hunting for the direction of the device as soon as it is detected.
While the most obvious countermeasure is to turn your Wi-Fi card off when you don't need it, this may not actually work for all devices. While airplane mode may be an acceptable option for some users, the majority would find cutting off all communications to their device too inconvenient for the added benefit of privacy.
For added safety and privacy, you should also go through your device and delete any networks you no longer connect to, especially any networks that don't require a password. These networks being stored in your phone allow anyone to create a network with the same name and either decloak or take over your device's data connection.
I hope you enjoyed this guide to detecting when devices are nearby by tracking their MAC address!

I'd like to use this method in school project to detect when the buses arrive by attaching esp in each one of them. I'm planning to make changes to the code but i have no idea how to do it. As with any other kind of malware, stalkerware can usually be spotted by a third-party security suite: We don't have room for a full guide here, but the likes of Norton , Bitdefender and Malwarebytes have both Windows and Mac options.
Bear in mind that spyware won't typically list itself under its real name, and may well try and pass itself off as a system app or use a short name that you're likely to overlook. Check through all the tabs that come up in the dialog on screen. Should you see anything that you don't recognize, or anything that doesn't match up to the programs you know you have installed, or that just seems suspicious in its behavior excessive disk usage maybe , then a quick web search for the app or process name is usually enough to reveal what you're dealing with.
You should also check for applications and processes that are starting up at the same time as your operating system, as most surveillance tools will need to do this. Again, run a web search for any application that you're not sure about. Check the entries for Input Monitoring and Full Disk Access , as spying software will often need these permissions.
Windows doesn't have exactly the same setup, but you can see the permissions that apps have including location, camera access and so on by choosing Privacy from the Settings menu and scrolling down to App permissions. As we've said, if your employer is keeping tabs on your working day then the tools should be visible and running with your knowledge. But if you're really worried, a complete system reset for Windows or macOS should clear the majority of hidden monitoring tools, if you suspect one has taken root just make sure you back up your files first.
For someone who wants to invade someone's privacy, it's often easier just to gain access to their online accounts rather than try to get access to their devices. With just about everything accessible on the web, from social media to email, it's far more effective.
With that in mind, as well as checking for unauthorized access to your devices, you should also check for unauthorized access to your accounts. This obviously starts with protecting your usernames and passwords: Make sure they're known only to you, difficult to guess, not used across multiple accounts, and not written down anywhere.
