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 this project, a smart socket is designed which can be automatically switched using a relay. The socket is interfaced to a Particle Photon based IoT device which keeps track of energy consumption using ACS 712 Current sensor and help automatically disconnect socket connection with the Mains when the power consumption by a device exceeds a threshold value. The Photon also remains connected to a web server via Wi-Fi hotspot and keeps updating the energy consumption data to the server.
Augmented Reality and Mixed Reality are the future of human interaction with the real world. Augmented Reality is a technology that allows projecting live images, videos or media in the real-world environment along with the real objects visible through a camera or holographic wearable.

It is a way of modifying the view of real world environment by a computer. In this project, Augmented Reality is used to monitor the sensor data supplied through an IOT board. The IOT board used in the project is Particle Photon.
New developments in System-on-Chip (SoC) devices — which provide optimal energy and connectivity characteristics and sensor integration — are expected to gain momentum in the market. Essentially, SoC is an integrated circuit that includes all components, such as a central processing unit, memory, and others, on a single microchip. Although these first-generation chips are already…
In the previous tutorial, features, advantages and limitations of TCP/IP Protocol were discussed. Though, TCP/IP is not best suited for IoT applications due to packet overheads, still being the most common protocol stack on internet, it offer ubiquitous connectivity. An IoT device can be made to communicate with a cloud or server using TCP/IP protocol without any hassle of network programming and network administration. In this project, an IoT device will be designed that could transmit sensor data to ThingSpeak Platform using the TCP/IP protocol.
The vehicle tracking systems are designed for tracking the movement of a vehicle from a location at any time. Such system is equipped with a GPS receiver which maintains the GPS location of the device. The GPS location of the device traced by the GPS sensor is sent to a cloud server or cloud service with the help of a controller. This project is a simple implementation of such system on one of the most popular prototyping boards – Arduino UNO.
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.
Medical Electronics is also going to advance with the application of Internet of Things. Internet of Things is the fastest growing technology. IoT is about to find application everywhere and in everything. In this project, a simple patient health monitoring device is developed as an IoT application. This IoT device could read pulse rate and measure surrounding temperature. It continuously monitors the pulse rate and surrounding temperature and updates them to an IoT platform. The IoT platform used in this project is ThingSpeak.
Gardening is a common hobby for nature lovers. The plants need continuous and closely monitored care. Sometimes, this turn into a liability. Like when the care taker of a home garden needs to go out of station for a while, the garden may remain unattended for some time or even long time. The Internet of Things can offer a feasible solution to this. The garden can be modernized with electronic technology that continuously monitors the conditions of plants and soil, so the plants could be provided watering and shade as required. All of this can be controlled and monitored online with the application of IoT.
Internet of Things is the fastest growing technology. Like Information Technology revolutionized every field in the early years of twenty first century, the internet of things is about to forward the same legacy. IoT is about to find application everywhere and in everything. The concept of IoT is so scalable, versatile and ubiquitous. In this project, Internet of Things has been used to built a visitor counter which can be monitored online. Such visitor counter can be part of a home automation system or smart home system.
Food safety and hygiene is a major concern in order to prevent the food wastage. The Quality of the food needs to be monitored and it must be prevented from rotting and decaying by the atmospheric factors like temperature, humidity and dark. Therefore, it is useful to deploy quality monitoring devices at food stores. These quality monitoring devices keep a watch on the environmental factor that cause or pace up decay of the food. Later, the environmental factors can be controlled like by refrigeration, vacuum storage etc.
In the previous tutorial, IoT communication between two devices over Zigbee protocol was demonstrated using two Xbee modules. The two modules were communicating with each other automatically without any human intervention. The two modules were also operating in transparent mode in the previous project. In this project, an LED light controller is designed where one device controls the LED interfaced at other by communicating data in API mode.

In this tutorial, learn to perform simple Client to Client Communication over Zigbee Protocol. There will be two Xbee modules taken and will be configured to communicate data with each other over the air. The Xbee devices communicate with each other wirelessly over the air. They do not have any microcontroller or processor in themselves, so they cannot manage the received or sent data.
In the previous tutorial, advantages of CoAP protocol over TCP/IP and UDP protocols in IoT applications were discussed. The CoAP protocol is specially designed for constraint devices and networks.
