Giving human senses to "things" to make our lives more convenient.

Sensors for IoT applications

Sensors capture environmental information and convert it into digital data

Ubiquitous sensors make IoT devices smarter, enabling the “things” involved to “see”, “hear”, “feel”, “smell” and therefore understand their surroundings. They mark the "point of beginning" of each IoT system, picking up data from the environment surrounding a connected device.


Infineon’s broad portfolio of XENSIV™ sensors for IoT applications is meeting today’s sensing challenges reliability, accuracy and application fit. It covers a wide offering for smart cars, smart factories, smart homes and buildings as well as smart things including pressure and magnetic sensors, acoustic sensors, 3D image sensors, radar sensors and COsensors to name just a few examples. Building on the company’s in-depth system understanding, we provide perfect-fit sensor types, giving customers the widest selection of ready-to-use sensor solutions for IoT applications offering fast time-to-market. Additionally Infineon boasts an excellent selection of ready-to-use solutions with a short time-to-market.

New solution example: High-precision sleep monitoring at home based on radar technology

We link the digital world with a holistic portfolio of sensors for intuitive sensing. With these innovative solutions, we help solve everyday challenges.

One example of this is the high-precision sleep monitoring at home based on radar technology:

Billions of people are facing sleep problems like sleep apnea, an interrupted breathing during the night. This is leading to various health consequences including snoring, daytime fatigue, along with more difficult issues such as heart problems and diabetes. Diagnosing sleep apnea is challenging and often includes observing a patient in a sleep laboratory, a stressful situation which can lead to deviating results. To solve the issue, we are collaborating with Sleepiz AG, a Swiss digital health company. Together, we provide a solution for easy-to-use sleep monitoring at home. 

Watch the video and learn more about the XENSIVTM sensor portfolio and get insights into the solution for easy-to-use sleep monitoring at home, based on Infineon XENSIV™ 60 GHz radar technology and Sleepiz-proven machine learning algorithms.

REAL3™ 3D image sensor based on Infineon ToF (Time-of-Flight) technology - powering the smallest depth-sensing 3D camera modules in the market. Enabling secure, password-free, contactless mobile user experiences, our REAL3™ ToF 3D image sensors are ideal for fast, seamless, and spoof-proof facial identification in applications like phone/app unlocking, mobile payments, and much more. Applications like entrance control or presence detection for smart home and smart building benefit from Infineon's complete turn-key radar presence detection solution based on XENSIV™60 GHz radar with integrated PSoC™ 6 MCU and software libraries. The BLE functionality is monolithically integrated on MCU. And the radar sensor can be easily and remotely controlled via smartphone app. It's amazing what a big role touch sensors already play in our daily lives, for example in the use of smart watches, smart phones, wireless earbuds and more. Capacitive sensors use the electrical properties of the human body as input and detect differences in capacitance caused by a human finger when it is in close proximity to the sensor. Infineon's CAPSENSE™ capacitive touch sensing technology measures changes in the capacitance between a plate (the sensor) and its environment to detect the presence of a finger on or near a touch surface. Gaming, virtual e-Commerce, 3D online education: Augmented Reality (AR) applications with three-dimensional depth sensors link the real with the digital world and are strongly demanded. The REAL3™ ToF sensor enables seamless augmented reality sensing experiences with high quality 3D depth data capture up to a distance of ten meters, without losing resolution in the shorter range. Always-on applications such as mobile AR gaming can greatly benefit from the small power budget required by the new sensor, and provide users with longer playtime than ever. For applications such as the 3D scanning for room and object reconstruction or 3D mapping for furniture planning and other design applications the sensor allows to double the measuring range beyond the current solution in the market. The sensor fusion based alarm system is a multi-layered security system that uses data from XENSIV™ IM69D130 microphone and XENSIV™ DPS310 barometric pressure sensor to provide true protection against burglary and intruder events. This unique glass break and intrusion detection concept provides robust protection with reduced false alarms. Both hardware components operate on separate algorithms and thread it into one with a sophisticated sensor fusion algorithm.
