CO2 sensor "SCD43"

High-quality sleep is essential for maintaining cognitive function and physical recovery. However, in recent years, it has become increasingly difficult to secure restorative sleep, and one of the factors behind this is the growing concern about indoor air quality (IAQ). Recent findings suggest that insufficient ventilation and rising indoor CO₂ levels may impact sleep quality, brain function, and the autonomic nervous system. CO₂ concentration is a representative indicator of indoor ventilation conditions, and monitoring with CO₂ sensors allows for quantitative assessment of invisible environmental factors. <Reasons for the focus on CO₂ monitoring> ■ Stable measurements using proven sensing technology ■ Compatibility with a wide range of applications, including HVAC, smart devices, and healthcare equipment ■ Support for compliance with major indoor environmental standards such as WELL and RESET <Examples of applications> ■ Air conditioning and ventilation systems, indoor air quality (IAQ) monitors ■ Smart home devices and healthcare-related devices CO₂ monitoring contributes to creating a more comfortable and healthy sleep environment by visualizing environmental data and leading to actions such as improving ventilation. For details on the features and specifications of CO₂ sensors, please refer to the catalog.

We exhibited at the exhibition "Smart Sensing 2025," held at Tokyo Big Sight from June 18 to 20, 2025. A diverse range of technologies and products that expand future possibilities, from sensor technology to AI and data utilization services, were showcased, and many visitors came to our booth. This time, along with our environmental sensors, flow sensors, and automotive modules, we also displayed six types of demonstrations. SEN66: Indoor Air Quality Combo Sensor Module SGD43S: Refrigerant Detection Sensor SCD43 / STCC4: CO₂ Sensor SLF3S: Liquid Flow Sensor SAAF: Fogging Detection and Automatic Defrost Sensor Visitors had the valuable opportunity to see products that cater to a wide range of applications, including air quality measurement, gas leak detection, visualization of factory safety management, and flow measurement and control in the semiconductor, medical, and research fields, while experiencing the sensors' fast response and high precision. Thank you very much to everyone who visited our booth. We sincerely appreciate the many attendees who contributed to the lively atmosphere of the exhibition each day.

Sensirion plans to launch its latest photoacoustic NDIR CO2 sensor, the "SCD43." It will be available through Sensirion's channel partners in the summer of 2025. This compact and high-precision CO2 sensor is an improved version of our proven SCD4x photoacoustic NDIR CO2 platform, designed to meet stringent building code requirements. Product Overview: - Compatibility with the comprehensive building standard ASHRAE 62.1 Draft Addendum d - Industry-leading measurement accuracy (±30ppm + 3% m.v.) - Drop-in upgrade for SCD4x sensors - Compact form factor of 10.1 x 10.1 x 6.5 mm - SMD solderable CO2 concentration is a critical indicator for assessing indoor air quality (IAQ), and elevated levels can negatively impact cognitive function and health. Air quality monitors and devices utilizing the SCD4x contribute to the proper management of CO₂ levels, helping to maintain a healthy and productive indoor environment.
