If you are working on IoT project, you are here at right place. We are one stop shop for IoT needs and providing training alongwith end-to-end solutions offering.

Four things form basic building blocks of IoT system –sensors, processors, gateways, applications. Each of these nodes has to have their own characteristics in order to form an useful IoT system.

Simplified block diagram of the basic building blocks of the IoT


These form the front end of the IoT devices. These are the so called “Things” of the system. Their main purpose is to collect data from its surrounding (sensors) or give out data to its surrounding (actuators).

These have to be uniquely identifiable devices with a unique IP address so that they can be easily identifiable over a large network.

These have to be active in nature which means that they should be able to collect real time data. These can either work on their own (autonomous in nature) or can be made to work by the user depending on their needs (user controlled).

Examples of sensors are: gas sensor, water quality sensor, moisture sensor etc.

We offer below all types of sensors:Processors:

Processors are the brain of the IoT system. Their main function is to process the data captured by the sensors and process them so as to extract the valuable data from the enormous amount of raw data collected. In a word, we can say that it gives intelligence to the data.

Processors mostly work on real-time basis and can be easily controlled by applications. These are also responsible for securing the data – that is performing encryption and decryption of data.

Embedded hardware devices, microcontroller etc are the ones that process the data because they have processors attached to it.

We offer various types of processors as per project need.PremierWave2050 Embedded IoT Gateway Beauty Shot

IoT Gateways

Gateways are responsible for routing the processed data and send it to proper locations for its (data) proper utilization.

In other words, we can say that gateway helps in to and fro communication of the data. It provides network connectivity to the data. Network connectivity is essential for any IoT system to communicate.

LAN, WAN, PAN etc are examples of network gateways. We offer various types of gateways as per your project need.

Applications form another end of an IoT system. Applications are essential for proper utilization of all the data collected.These cloud based applications which are responsible for rendering effective meaning to the data collected. Applications are controlled by users and are delivery point of particular services.Examples of applications are: home automation apps, security systems, industrial control hub etc.

In Figure , the extreme right block forms the application end of the IoT system.

Figure : Basic building blocks of IoT

In a nutshell, from the figure we can determine that the information gathered by the sensing node (end node) is processed first then via connectivity it reaches the embedded processing nodes that can be any embedded hardware devices and are processed there as well. It then passes through the connectivity nodes again and reaches the remote cloud-based processing that can be any software and are sent to the application node for the proper applied usage of the data collected and also for data analysis via big data.


How the IoT works is quite simple.

First, it acquires information with respect to basic resources (names, addresses and so on) and related attributes of objects by means of automatic identification and perception technologies such as RFID, wireless sensor and satellite positioning, in other words the sensors, RFID tags and all other uniquely identifiable objects or “things” acquire real-time information (data) with the virtue of a central hub like smartphones.

Second, by virtue of many kinds of communications technologies, it integrates object-related information into the information network and realizes the intelligent indexing and integration of the information related to masses of objects by resorting to fundamental resource services (similar to the resolution, addressing and discovery of the internet).

Finally, utilizing intelligent computing technologies such as cloud computing, fuzzy recognition, data mining and semantic analysis, it analyzes and processes the information related to masses of objects so as to eventually realize intelligent decision and control in the physical world.
