Carbon dioxide sensor.

Engineered for accuracy, built to endure.

The SCD53 CO₂ sensor, from Sensirion, is designed to address an increasingly relevant challenge in gas sensing: maintaining accuracy long-term without relying on costly manual recalibration or regular exposure to outdoor fresh air. This their next generation high-performance CO₂ sensor is to be launched in late 2026.

Many sensors in use today successfully apply automatic baseline calibration algorithms (i.e., “ABC” or “ASC”) to maintain their accuracy over time. These assume regular exposure of the sensor to air at the atmospheric baseline concentration. However, not all applications can guarantee fulfillment of this condition, including demand-controlled ventilation (DCV) systems for permanently occupied spaces, exclusively mechanically ventilated buildings, or smart greenhouses.

The SCD53 combines Sensirion’s leading expertise in photoacoustic NDIR sensing with advanced laser technology for excellent long-term stability independent of fresh-air based recalibration algorithms. Furthermore, the sensor provides best-in-class accuracy, with robustness against dust, vibrations or mechanical forces. Integrated humidity and temperature compensation, as well as optional pressure correction, enable reliable readings across a demanding range of environmental conditions. On-demand measurements, compact sensor size and a reflow solderable LGA package make integrating SCD53 simple, flexible and cost-efficient.

Little cube aids air quality.

Picture a classroom filled with children, their eyes heavy, faces reflecting fatigue, and motivation at an all-time low. This scenario is an all-too-common occurrence – not just in classrooms, but in every indoor environment. It highlights the often-overlooked importance of indoor air quality. The team at QE recognizes that the air we breathe has a profound impact on our lives and introduced an intuitive game-changer for everyone – the Wuerfeli. A compact, pyramid-shaped CO₂ monitor that continuously monitors the air you breathe while adjusting its brightness to fade into any scenery.

Stäfa, Switzerland – Fresh air not only heightens your concentration but also significantly reduces the risk of respiratory infections like influenza. Regular ventilation is the key to unlocking numerous benefits such as preventing mold, overall well-being, sharpening your concentration and reaction capabilities significantly, while combating fatigue. But how do you know when indoor air quality is poor, and you need to take a ventilation break? This is where Wuerfeli comes into play.

As the name suggests (see below), the core of Wuerfeli's brilliance is the world's smallest, highly accurate, cube-shaped CO₂ sensor – the SCD40 by Sensirion. With it, the device transforms you into an air quality expert, guiding you through the invisible pathways of air, optimizing your living space's air quality every day. To ensure your indoor air is as oxygen-rich and fresh as outdoors, the Wuerfeli uses four colors to visualize when to open and close your windows. Say goodbye to guesswork and welcome the simplicity of fresh air with a flick of a switch: 

● Blue:     Close the windows, the air is as fresh as outside
● Green:   Good room air quality
● Orange:  Ventilation is recommended due to decreased cognitive performance
● Red:       Air exchange needed – 1 in 30 breaths consists of previously exhaled air

In addition, Wuerfeli's unique pulsating mode in combination with the blue color helps you reduce ventilation time and minimize energy loss.

“We are thrilled to be partnering with Sensirion for such a meaningful cause. The SCD40 and the SHT40 are a perfect fit for Wuerfeli. High accuracy, unmatched price, and smallest form factors have allowed us to create a compact and affordable CO₂ monitor for everyone and everywhere”, says Laurin Schwitter, Co-founder of QE.

Wuerfeli also plays a central role in two major air quality studies conducted in 100 Swiss schools, where the Swiss-based company was able to prove a 63% reduction in COVID-19 infections in well-ventilated classrooms. Its high-precision measurements provide valuable insights into building design, insulation, ventilation behavior, and, most importantly, the demonstration of the “Wuerfeli Effect”: An apparent improvement in overall indoor air quality thanks to the intuitive color system that turns anyone into a ventilation pro in just a few days.  A clearly noticeable improvement. 

This partnership highlights both companies’ commitment to improving the health and comfort of people worldwide. "We want to inspire you to embrace a new level of air quality awareness. Don't just live; thrive with the gift of fresh air."

Mobile Carbon Dioxide detector.

Monitoring air quality, especially carbon dioxide (CO₂) levels, has gained widespread public attention in the past few years. A space with low CO₂ and fresh air represents adequate airflow, which effectively improves work and study efficiency and reduces the risk of fatigue, headaches, and drowsiness.

The brand new Meawow (a global brand under ZenMeasure Technologies) Mini Bluetooth CO₂ detector (H411) equipped with the Sensirion CO₂ sensor was officially released in June 2023, becoming the smallest portable Bluetooth CO₂ detector currently available on the market. The device is designed for convenient portability and thanks to its small size, it is the lightest and most compact design globally, allowing it to be carried around like a mobile phone for on-the-go measurements. It features a built-in battery that can be charged via a USB Type-C port, supporting extended standby time.

The intelligent design offers multiple measurement modes that service to various usage scenarios, supporting one-click single measurement or four-hours continuous measurement. It can provide CO₂ concentration readings within five seconds. Additionally, it can measure environmental temperature and relative humidity and supports multiple display modes, including Fahrenheit and Celsius. One thoughtful design aspect is that it also functions as a clock display – when hung on a backpack, it can serve as a mini clock, as well as a temperature, humidity, and CO₂ measurement device.

The Meawow Mini CO₂ detector's display interface includes user-friendly indicators in red, yellow, and green, providing simple and convenient visual cues. Apart from displaying accurate numerical values, it uses the three-color status bar and LED lights to remind users of CO₂ concentrations. Furthermore, the product supports a Bluetooth connection with the Meawow app, allowing users to record historical data on their mobile devices. It also offers features like LED light disabling for undisturbed mode and CO₂ measurement calibration.

"The high-precision and ultra-compact CO₂ sensor from Sensirion has helped us achieve a portable design with the smallest size and highest measurement accuracy. We are delighted to see that thanks to this collaboration, our product has become the most lightweight, intelligent, and long-lasting wireless Bluetooth CO₂ detector globally. It helps users to improve the air quality in their surroundings by enabling them to measure CO₂ levels anytime and take timely actions to enhance their health." said Mr Yuyang Liang, the founder of ZenMeasure.

Measuring hydrogen in the fuel cell.

The leading developer and manufacturer of core parts for automotive electronic management systems in South Korea has recently launched a hydrogen leak detector that provides reliable real-time monitoring. To achieve maximum durability even in the harshest environments, Hyundai Kefico relies on Sensirion sensors.

“Sensirion and Hyundai Kefico are both committed to creating a cleaner and more sustainable world. Thanks to this valuable partnership, we have succeeded in developing a hydrogen detector sensor that achieves maximum durability and reliability even in the harshest environments. Together, we are striving to achieve our goal.” Moonsung Shin, Team manager of Sensor Design at Hyundai Kefico.

Fuel cell electric vehicles (FCEVs) have become increasingly important in recent years as the demand for cleaner alternatives to petrol and natural gas has grown. FCEVs are similar to other electric vehicles in that they use electricity to power an electric motor. What sets them apart, however, is that FCEVs generate electricity using a fuel cell that is powered by hydrogen, rather than drawing electricity from a battery alone. In the fuel cell stack, pure hydrogen (H2) flows through a membrane and combines with atmospheric oxygen (O2) to produce electricity. However, because hydrogen has a lower ignition energy than petrol or natural gas and therefore ignites more easily, there is a risk of explosion if the hydrogen leaks.

The answer to this problem is a sensor that constantly monitors the level of hydrogen in the fuel cell. To minimize vehicle failures, Hyundai Kefico has developed a hydrogen gas sensor that detects even the smallest hydrogen leaks in vehicles in real time, ensuring driver safety. Once a hydrogen leak is detected, the sensor outputs a signal in the form of analog voltages. The vehicle can then initiate all relevant safety mechanisms to prevent breakdowns. This makes the sensor ideal for applications such as fuel tanks, delivery systems and fuel cell stacks.
