Do-it-yourself IoT: May the force(s) be with you!
Thanks to a do-it-yourself Internet of Things (IoT) project I was working on a few weeks ago, I had an opportunity to reflect on the rapid pace of technology and innovation.

Over the last 25 years, four fundamental forces representing computing concepts and movements have gained momentum. Together, they helped integrate hardware, software, and the physical environment in a way that is intuitive and accessible to a do-it-yourself audience. These forces are:
- Open-source software from the '90s,
- Cloud computing from the early 2000s,
- Maker movement since 2005, and
- Low-code development platforms in the current decade
Before we look at these four forces more closely, let’s take a look at the project.
Objective: To design a system that will monitor the temperature of my home environment and trigger a text message to my phone when the temperature crosses a certain threshold.
What I needed:
- Sensors to measure environmental conditions like temperature, humidity, etc.
- Raspberry Pi 3: A credit-card sized computer that has an HDMI port to connect to monitor and a USB port to connect to keyboard/mouse
- A smartphone
- Raspbian: An operating system built for the Pi
- Node-RED: A visual programming tool for wiring hardware devices, APIs, and online services to facilitate the Internet of Things
- A cloud-based communication platform that allows you to send SMS to your phone
- A cloud-based IoT platform that allows devices to interact with other devices and cloud applications
Sensors attached to a Raspberry PI 3 continuously monitor the temperature in the surrounding environment; when a predetermined threshold is met, an alert is sent through the IoT platform to the user’s smartphone.
How it worked:
The four forces at work
Now, let's look at how the four forces came together in this project.
- Cloud computing: In the early 2000s, Salesforce2 pioneered the concept of enterprise app delivery via the Internet. Remember the “no software” days? Since then, almost anything tech is delivered “as a service.” Thanks to the cloud delivery model, a cloud-based communication platform, and the entire IoT platform are represented in this project. Worldwide public IT cloud service revenue3 in 2018 is predicted to be $127 billion.
- Maker Movement: In 2005,4 with the launch of MAKE Magazine, the tech-influenced DIY community has come to be identified as the Maker Movement5. Recently I attended a Maker Faire, called the “greatest show and tell on earth,"6 and sat on a 3D printed chair! Affordable, intuitive tools and hardware have fueled the rise of the Maker Movement and enabled DIYers like me to tackle our own technology projects. Pi7 and Arduino8 are available for under $50 and frequently used in DIY projects. Industry stats on the movement estimate9 that makers fuel about $29 billion into the economy each year.
IoT takes hold
According to Deloitte, the Internet of Things is taking off in both consumer-focused and B2B industries, and our Tech Trends research has identified the move from sensing to doing. There are multiple platforms of choice and robust offerings from several technology leaders and specialized providers. GE predicts12 investment in the Industrial Internet of Things is expected to top $60 trillion during the next 15 years. The possibilities in the universe of connected things are only beginning to be realized; the real potential lies in making data actionable and uncovering valuable insights.
An iota of that investment is more than enough to start your own prototypes. As you start your next IOT project, may the force(s) be with you!
