In the previous tutorial, we discussed Internet of Things (IoT) platforms. As IoT solutions scale in size and complexity, these tools become essential for managing devices, data, and overall system performance. However, not all platforms serve the same function. Generally speaking, they fall into categories such as device management, connectivity management, application enablement, cloud integration,…

By 2025, an estimated 30 to 40 billion connected devices are expected to be in use worldwide. As of late 2024, over four billion cellular IoT connections. Industries now rely on the Internet of Things (IoT), encompassing everything from industrial systems and smart cities to healthcare and logistics. As these systems grow in scale and…

Traffic light systems have been in use for over 100 years. However, urban mobility faces new challenges worldwide with rising population densities, expanding road networks, and increasing car ownership. Originally designed to manage traffic with minimal human intervention, today’s traffic light systems are expected to do much more. They now play a critical role in…

Learning Guide to IoT A learning guide for IoT (Internet of Things) will help understand the basic concepts, tools, technologies, and steps involved in building IoT solutions. Here’s a step-by-step guide to help you navigate through the different aspects of IoT: Introduction to IoT Definition: IoT refers to a network of physical devices, vehicles, appliances,…

In the previous tutorial, ESP8266 module was used to design a Home Area Network to control an LED light from a remote PC. The PC client was used to send control signals to switch on and off the LED light in the Home Area Network. In this tutorial, the ESP module will be interfaced with DHT-11 temperature sensor and temperature  data will be sent to the PC client for real-time temperature monitoring. In this project, instead of LED, the DHT-11 sensor will be interfaced with the ESP8266 on ESP Client side.

In this tutorial, we’ll learn how to use device-to-device (D2D) communication to make daily life a little simpler. For example, you’ll be able to control household appliances, such as the coffee machine, a light switch, or the AC — and do so from inside your vehicle. So, if you’re arriving home one evening, the presence…

In this project we are going to make heart beat monitor system which will be able to send the readings in bpm to the doctor directly through internet using MQTT protocol from anywhere in the world. The ESP 8266 and Arduino are used to read the reading from sensor and then send them to the…

In this article, we will be detecting a forest fire using an IoT sensor network and making a portable device with battery operation. Getting information about a fire hazard in a forest in time can prevent the forest fire from spreading. The sensor network can give the particular location of the fire as we already…

In the previous tutorial, FTP protocol and file transfer over it between a Client and Server was discussed. The FTP protocol can really useful in many IoT applications. Many IOT devices are installed in places like nuclear plant, electrical grids and other industrial setups where these types of devices can get some bugs and need application software updates to fix them. On standard IoT protocols like MQTT, CoAP, etc, it is hard to update and reinstall application software because most of the IoT protocols are designed for IoT communication between devices and network but not for tasks like application updates.

Nowadays, most of the hotels and restaurants take online orders of food. Many hotels and restaurants either facilitate pre-ordering or even render delivery services in the local areas. In this project, an Hotel Order Management System is designed where a customer can pre-order food items using a mobile app and a Raspberry Pi based Server manages to cater menu items and book orders.

In the previous tutorial, it was mentioned that IMAP protocol is a standard email protocol which is used to store email messages and retrieve them. It was also mentioned that IMAP protocol can be used in IoT applications where commands can be passed to IoT devices by emails. This can be really helpful in certain situations like when security might be the main concern. Also, emails can be sent on any network without any special application or permissions. The IoT devices can receive emails as email clients where they can read emails and process information contained in them.

The idea of a smart home first took hold in 1975 when Pico Electronics introduced the X10 protocol and devices designed to control electronic appliances using power lines. However, computers were not yet advanced enough for automation or remote control. As technology evolved, so did automation. Microcontrollers played a critical role, but the early systems…

Smart technology refers to devices and systems that use advanced computing, connectivity, and data analytics to enhance functionality and efficiency. Devices such as smartphones, watches, and appliances connect to the Internet and one another via the Internet of Things (IoT), allowing for real-time data exchange and remote control. One innovative application of this technology is…

Since its launch in 1999, MQTT (Message Queuing Telemetry Transport) has been a valuable standards-based messaging protocol for automation applications. Its lightweight, efficient “publish-subscribe” model makes it ideal for communication between and across various devices, systems, and services. MQTT has transformed applications in supply chain management, quality control, predictive maintenance, M2M communication, and industrial energy…

The Internet of Things (IoT), a collective network of connected devices that communicate via the Internet, transforms how we live, work, and interact with objects in our environment. By integrating real-time connectivity and cloud computing into everyday devices, IoT enables real-time data collection and analysis, facilitating better decision-making and personalized experiences. For example, it can…

Electronics makers often build mobile apps to control electronic devices. These are typically WiFi or Bluetooth-connected devices controlled by a smartphone. Several software frameworks and tools support the development of native or cross-platform mobile apps for iOS and Android. Some popular frameworks include React Native, Flutter, Xamarin, Swiftic, Ionic, Apache Cordova, Jquery Mobile, and Native…

Are you building something that requires a GSM/GPRS modem or looking for a GSM modem for your next IoT project? GSM modems are widely used in several connected devices and applications. GSM is an acronym for Global Systems for Mobile, and GPRS refers to a General Packet Radio Service. A GSM module is a device…

The Internet of things (IoT), which includes the billions of devices now connected to the internet, has developed substantially over the past few years. IoT has become integral to several technologies and businesses. In fact, the number of active IoT devices has increased from 11.28 billion to 13.14 billion between 2021 and 2022. And the…

The Internet of Things (IoT) refers to a network of interconnected devices that communicate to perform specific tasks or applications. These devices are extensive and include vehicles, appliances, sensors, software, or web services. Effective communication is crucial in any IoT application, allowing these devices to work seamlessly. In an IoT network, device-to-device communication is distinct.…

Many communication technologies are currently available, making choosing one for an Internet-of-Things project potentially daunting. For example, several LP-WAN options exist, including Wi-Fi, Ethernet, LoRa, Zigbee, Bluetooth, and cellular technologies like NB-IoT, LTE-M, and 5G. Every connectivity solution has pros and cons, and there isn’t one ideal for all projects. Wi-Fi might seem like the…
