With continuous advancements in sensor and networking technology, the Internet of Things (IoT) is taking shape as an ever-present always-on global computing network. The most critical piece in the IoT puzzle are the sensors and this is a short introduction to the IoT Internet of Things Sensors.
The Internet of Things means different things for different people. From the viewpoint of connectivity, IoT means “from anytime, anyplace connectivity for anyone, and for anything”. From the viewpoint of communication, IoT is “a global network of interconnected objects uniquely addressable based on standard communication protocols”. Finally, from the viewpoint of networking, IoT connects “a network of interlocked computers to a network of interconnected objects”.
IoT means a “Smarter World”
The number of devices and industries connected to the internet is exponentially increasing and having all of them interconnected via wire or wireless will put a powerful source of information at your fingertips.
Fun historical fact, before we start! Did you know that the IoT is not something new ? In 1982, a modified coke machine at CS Department of CMU, was connected to the IoT which was able to report the number of drinks contained and also reports whether the drinks were cold or not.
IoT promises to deliver an always-on, always-connected world of devices and convenience. At the same time, IoT poses significant challenges that could stand in the way of realizing its potential benefits.
A survey result published by Gartner Research report on the IoT, billions of devices are already connected in 2015 and that number will climb to 25 billion in next few years. According to this report, IoT offers promising solutions to transform several industrial applications such as agriculture, environmental monitoring, security surveillance, food processing industry, logistics, and more.
The Role of Sensors in IoT
Leveraging IoT’s identification, sensing, and communication capacities, all the objects in the healthcare are continuously monitored and tracked. In particular, biomedical sensors are the entry post for data into the IoT.
Food Supply Chain
IoT networks are designed to address traceability, visibility, and controllability. The Internet of Things Sensors for Food Supply Chain comprises of three parts:
1) the field devices – WSN code, RFID tags and user interface terminals
2) the back-end systems include: databases, servers, and terminals connected by distributed computer networks
3) the communication infrastructures including WLAN, cellular, satellite, power line, Ethernet, etc.
Sense Mine Disaster
Specifically designed to sense mine disaster signals in order to make an early warning, disaster forecasting, and safety improvement. IoT sensors track the location of underground miners and analyze safety data collected from sensors to enhance safety measures.
To detect potential fire and to provide early warnings for possible fire disasters. Featured with RFID tags, mobile RFID readers, intelligent video cameras, sensor networks, and wireless communication networks, IoT Fire Sensors could perform automatic diagnoses to realize real-time environmental monitoring.

Internet of Things Sensors Revolution
Now you are aware of what IoT is, its applications and leading manufacturers. Let us now understand how smart sensors are transforming the IoT
- Sensors are the indispensable enablers of IoT. The Internet of Things sensors with Radio Frequency Identification (RFID) tags serve three purposes, i.e. identify items, locate them and determine their environmental conditions.
- Smart Internet of Things Sensors impact the food supply chain which can improve the manufacturing process of the products. They take control of the entire manufacturing process to monitor, control, and improve operations.
Important Applications of Internet of Things Sensors for Smarter World
IoT – The big wave of connectivity is going beyond laptops and smartphones and it’s going towards interconnecting cars, smart homes, and smart cities. Continue reading to know how applications of IoT transform our lives and the areas where IoT will make a huge impact on business and society.
