[Editor's Note] When smoke is detected inside a home, a fire detector sounds, nearby firefighting equipment activates, and an emergency call is sent to the homeowner and the fire department. Beyond firefighting, the implementation of such systems, which operate without human intervention, has become readily available and widespread in our daily lives, and it is expected that further advancements will occur in our daily lives in the future. Systems that connect and operate through the Internet of Things (IoT) without human intervention are called the Internet of Things (IoT). The IoT is already being applied to many aspects of our lives, whether we're aware of it or not, including healthcare, power, gas, parking, and home appliances. Accordingly, this magazine has prepared a five-part series to examine the cutting-edge technologies that make the Internet of Things possible.


■ Sensors , accurate monitoring of the surrounding environment

To implement Internet of Things (IoT) technology You need the skills to accurately perceive your surroundings.

For example, if you mistake a situation where smoke is generated while cooking for a fire and activate the sprinkler or call the fire department, you could waste unnecessary energy and waste time and resources.

Therefore, it is important to have technology that allows you to accurately perceive your surroundings by seeing, hearing, feeling, and smelling them.

In addition, we have entered an era where various sensors are required, and solutions that can integrate and operate these sensors and shorten the development period for these sensors are also needed.

The key technology for implementing IoT is sensors.

■ Smart objects, buildings, factories, and cars start with ' sensors '

In IoT, sensors are ubiquitous and the starting point of every IoT system, collecting all kinds of data about the surrounding environment.

Developing smart, networked IoT products is a truly challenging task. Topics such as interoperability between wireless and embedded systems, security, cloud integration, and energy management are time-consuming and require significant expertise.

Accordingly, the core sensor technologies required for IoT implementation include pressure and magnetic sensors , acoustic sensors , 3D image sensors , radar sensors , and CO2 sensor technologies.

Additionally, evaluation and demo boards and online simulation tools are needed to easily develop differentiated IoT solutions.

In the smart device sector, such as voice assistants, digital wallets, and fitness trackers, the following are available: △ MEMS microphones that can achieve enhanced audio performance even in highly demanding applications; △ Digital barometric pressure sensors featuring small size, low power consumption, highest precision, robustness against ambient conditions, and relative accuracy over a wide temperature range; △ Radar suitable for applications such as health monitoring, motion control, and presence detection; and △Face recognition-based authentication and AR/VR applications.Image sensors, etc. are required.

In the smart building field, which aims to improve comfort, energy efficiency, and security, the following are required: MEMS microphones that can implement voice control, capacitive sensors that can control devices by touch, radar sensors that can effectively detect motion, and image sensors that provide accurate depth data in real time, respond quickly, operate without contact, and have excellent robustness against ambient light.


As IoT is introduced to the industrial field , the smart factory area that will enable smart manufacturing will require current sensors suitable for industrial applications, high-precision coreless sensors , and image sensors that can capture a 3D map of the scene in front of the device.

The automotive sector, a convergence of IoT, requires reliable sensors. Environmental sensing is a cornerstone of smart cars. Radar-based driver assistance systems, such as adaptive cruise control and collision warning, and 3D cameras enhance passive safety through features like occupant detection and smart airbag systems.

As the number of IoT devices and applications increases, so does the volume of data traffic. Today, 16.3 zettabytes of data are generated and collected annually, and this figure is projected to grow to 163 zettabytes by 2025.

To process and transmit such massive amounts of data, the performance of the communication networks, data centers, and servers that form the backbone of the IoT must continue to improve. All systems that make up the IoT must operate reliably, as users and businesses demand reliable and uninterrupted connectivity, increasing bandwidth, storage capacity, and energy efficiency.
