The Internet of Things (IoT) is a network of billions of smart devices working with countless Internet-enabled digital services. One such service is weather forecast. Weather APIs integrate weather data with smart devices, websites, and online platforms. Several IoT applications use weather data, such as smart clocks, temperature control systems, as well as travel and…

We might not always appreciate them, but that morning wake-up alarm is important for everyday life. It ensures we wake up in time for work, school, meetings, appointments, or other essential tasks. Alarms can also help us keep a regular sleep/wake schedule.  In this project, we’ll use the Internet of Things (IoT) to set a…

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.

Internet of Things is meant to empower objects of day to day use with embedded electronics and IT infrastructure. It aims to connect these objects in real time with the internet network and allow them to communicate with other co-located or remote objects. For communicating with each other, the IOT devices need to follow protocols. An application developer need to take care primarily of the implementation of application layer protocols while usually the implementation of network and transportation layer protocols remain at the hand of network administrators or network programmers.

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 this article, we will be making an IoT-based pre-paid electricity system and learn exactly how that works. We will create a meter which will monitor the electricity usage and report to a monitoring server (which we will also create) for bills. In an ordinary electricity system, bills come after the usage, and then we…

One essential step in developing Internet of Things (IoT) applications is setting up communication between the IoT devices and a web server or services. IoT devices communicate with a web server, service, or an API through HTTP requests. An HTTP request is a message sent by a client to a server in the context of…

Automation has extended from industrial settings to homes and offices, with smart home devices and appliances becoming a part of our everyday lives. One challenge in the automation sector is creating flow and unity between the vast diversity of devices and applications. Automation has been further affected by various online services such as SaaS (Software…

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.

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.

In today’s world of communication, Long Range (LoRa) technology has taken a significant role, providing strong, long-distance connections. LoRa’s way of sending signals and its impressive reach make it an ideal option for many direct and indirect network paths. This article explores how LoRa works in two situations: when devices can see each other (line-of-sight…
