IoT or Internet of Things is a word we hear a lot. It is one of the most popular terms we associate with internet technology. Internet of Things, however, is simply not a fancy word. It represents the development of technology in association with the Internet.

To underscore its importance, many of our everyday devices now depend on the internet. These devices connect to a central network like your home’s WIFI and improve our comfort. Simple objects such as lights, fans, doors and other electrical devices can be used easily.

What makes these devices special are their electronic components and more 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 central network, you can program them to turn on as soon as you enter your room. This would be without any human intervention, as the sensors and other electronic components would be responsible for performing this function.

Importance of innovation in technology

With the improvement of technology, we also experience innovation in certain niches. One such niche is the sensor department. From sensitive sensors to smart actuators and other electronic components, the efficiency of our devices has increased dramatically.

Most IoT devices use high-tech components that are durable, cheap, and above all dependent. These incredibly small and impressive pieces of technology are a symbol of innovation. You can easily find these components in most, if not all, devices these days.

However, you don’t have to depend on companies to build these devices for you. You can build your own smart IoT devices using simple sensors and electronic components. Let’s look at some of the probable devices that you can easily build in your home.

1. Smart IoT lock with DIY components

Many of us struggle to keep the keys to our doors and locks secure. But what if you could have all the keys in your phone and only you could open doors with them? It was an interesting concept that has now become a reality for many of us. You also encounter such things in your daily life: portal key cards, automatic doors in escape roomsand many other places.

Such locks would use radio frequency identification (RFID) and DIY circuitry to open and close your locks. The whole project is relatively cheap. You will need some wires, a power supply, some resistors, a reader module to open and close the lock, and a microcontroller. You can find lots of 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 will be able to control your electronic devices such as fans, heaters, lights, and much more easily from your phone.

This DIY project involves two different types of sensors. It will use temperature, humidity, ultrasonic and humidity sensors. Other basic components include a microcontroller, battery source, wires, LEDs, and an IoT device platform (eg, Blynk).

3. Smart DIY lighting in your bedroom

Often we think 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 with no dynamic lighting effects or just a few pre-programmed effects.

Of course, making a DIY controller solves this problem. This DIY IoT project is quite simple and requires a few wires, 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 Sensor

We invest a lot in our security systems. Many of these security systems are a great example of IoT. However, not everyone can afford to buy these security systems, or they are not readily available. Do not worry; you can create your own smart motion detector.

To do this, you will need a microcontroller board, battery, motion sensor, wires, LEDs, and a few other components like resistors. After completing the circuit, you just need to connect the circuit to the internet and code it.

5. Smart DIY noise sensor

Amid growing concerns about pollution, noise has been a determining factor for many people in choosing their living space. The increasing noise in busy cities has prompted many people to try and get a noise sensor. But it’s easy to make your own DIY Smart IoT noise sensor.

To make this sensor, you don’t need a lot of components. You will need some wires, a sound sensor, an alarm, a microcontroller, Bluetooth, and an IoT device platform. This simple yet effective device will connect to your phone through a custom app that you can create easily using an app builder.

6. Smart DIY Item Tracker

Sometimes we tend to lose our things like keys, bags, wallets, etc. Having an item tracker can save us from spending hours trying to find our items. Building a DIY item tracker is very useful, especially if you have children. They often tend to misplace things, while we adults are guilty of doing the same from time to time.

To build such a device, you will need a SIM card, a battery, some sort of network sensor (antenna), a microcontroller, circuit boards, and wires, among other things. While this device might be a little bulky for your keys, you can easily use it for your bags and larger items. Once you get the hang of the build, you can condense the entire circuit to a smaller size that can inevitably be attached to keychains and keychains.

Conclusion

The IoT has many applications in our lives. From the simplest and most useful things to hacks that can change our lives. The coolest thing about IoT devices is that you don’t have to depend on someone to make it for you.

You can do it yourself with simple instructions and electronic components like sensors, microcontrollers, etc. Apart from the 6 Smart DIY IoT devices mentioned above, you can create many more using these electrical parts and sensors.
