IoT or Internet of things is a word that we hear a lot. It is one of the most popular terms we associate with Internet technology. Internet of things, however, is not a fancy word. Represents the development of technology in association with the Internet.
To underscore its importance, many of our everyday devices now rely on the internet. These devices connect to a central network like your home WIFI and enhance our convenience. Simple things like lights, fans, doors, and other electrical appliances can be easily used.
What makes these appliances special is their electronic parts and specifically their sensors. These sensors are incredibly efficient at transferring data and maintaining a connection to the core network.
For example, if you have lights connected to your core network, you can program them to come on the moment you enter your room. This would be without human involvement, as sensors and other electronic parts would be responsible for performing this function.
Importance of innovation in technology
With the improvement in technology, we are also experiencing innovation in certain niche areas. One of these niche areas is the sensor department. From sensitive sensors to smart actuators and other electronic parts, the efficiency of our devices has increased tremendously.
Most IoT devices use high-tech components that are durable, cheap, and most of all, reliable. These incredibly small and impressive pieces of technology are a symbol of innovation. You can easily find these components on most, if not all, devices today.
However, you don’t need to rely on companies to build these devices for you. You can build your own smart IoT devices using simple sensors and electronic parts. Let’s look at some of the probable devices that you can easily build in your home.
1. IoT smart lock with DIY components
Many of us struggle to keep the keys to our doors and locks safe. But what if you could have all the keys on your phone and only you could open the doors with it? It was an interesting concept that has now become a reality for many of us. You also find things like that in your daily life: access cards to the doors, automatic doors in escape rooms escapeand many other places.
Such locks would use radio frequency identification (RFID) and a DIY circuit to open and close the locks. The whole project is relatively cheap. You will need some cables, a power supply, a pair of resistors, a reader module to open and close the lock, and a microcontroller. You can find many videos for such projects.
2. DIY IoT smart device controller
Many people are hesitant to invest in IoT devices that can effectively control their devices. So why not build your own controller? You can control your electronic devices such as fans, heaters, lights and much more easily from your phone.
This DIY project involves a couple of different types of sensors. It will use temperature, humidity, ultrasound and humidity sensors. Other basic components include a microcontroller, a battery source, cables, LEDs, and an IoT device platform (eg, Blynk).
3. DIY smart lighting in your room
Many times we think that we could have more dynamic lighting in our rooms. Especially gamers who use RGB lighting in their rooms. One of the best parts of having such lights is the ability to control them. Most of these lights come without dynamic lighting effects or only a few pre-programmed.
Of course, making a DIY controller solves this problem. This DIY IoT project is pretty simple and requires some cables, a microcontroller, an IoT platform like blynk, and of course your RGB lights. Instead of standard lights you can also use an RGB LED matrix which will be easier to use.
4. DIY smart motion detector
We invest a lot in our security systems. Many of these security systems are a great example of IoT. Although, not everyone can afford to buy these security systems, or they are not readily available. Do not worry; you can make your own smart motion detector.
To do so, you will need a microcontroller board, a battery, a motion sensor, cables, LEDs, and some other components like resistors. After completing the circuit, you just need to connect the circuit to the Internet and code it.
5. DIY smart noise sensor
Amid growing concern about pollution, noise has been a factor in many people deciding their living space. The increasing noise in bustling cities has led many people to try to get a noise sensor. But it’s easy to create your own DIY Smart IoT noise sensor.
To make this sensor, you don’t need a lot of components. You will need some cables, a sound sensor, an alarm, a microcontroller, Bluetooth, and an IoT device platform. This simple but effective device will connect to your phone through a custom app that you can easily create with an app builder.
6. Smart DIY Item Tracker
Sometimes we have a tendency to lose our items like keys, purses, wallets and all that. Having an item tracker can save us the hassle of spending hours trying to find our items. Building a DIY item tracker is quite useful, especially if you have kids. They often tend to lose things, while adults are guilty of doing the same thing from time to time.
To build such a device, you will need a SIM card, battery, some kind of network receiver (antenna), a microcontroller, circuit boards, and cables, among other things. While this device may be a bit bulky for your keys, you can easily use it for your bags and larger items. Once you have mastered the construction, you can condense the entire circuit to a smaller size that can inevitably be attached to key rings and keyrings.
IoT has many applications in our lives. From the simplest and most useful things to the tricks that can change our lives. The most interesting aspect of IoT devices is that you don’t need to depend on anyone to do it for you.
You can do it yourself with simple instructions and electronic components like sensors, microcontrollers, and more. In addition to the 6 above-mentioned smart DIY IoT devices, you can do many more with these electrical parts and sensors.
