We spend much of our daily lives indoors, and indoor air can be up to five times more polluted than outdoor air. The introduction of air purifiers and high-precision sensors is essential for real-time detection of harmful substances such as PM2.5, VOCs, and CO₂, contributing to the creation of a healthy environment. Sensirion's SEN66 features an innovative compact design that can measure up to nine environmental parameters (PM1, PM2.5, PM4, PM10, temperature, humidity, VOC index, NOx index, CO₂). It simplifies integration and reduces costs. 【Key Features】 ■ Compliance with healthy building standards ■ Cost-effective combo module with multiple sensors ■ High-precision measurement and support for autonomous device control Experience the future of air quality sensing with the SEN66. 【Specifications (partial)】 ■ Mass concentration range: 0 - 1000μg/m3 ■ Standard relative humidity accuracy: 4.5% RH ■ Specified CO2 measurement range: 0 - 40000 ppm ■ Accuracy: ±50.0 ■ Sensor output: 0-500 VOC Index

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 AG will be exhibiting at the "Smart Sensing 2025" exhibition held at Tokyo Big Sight from June 18 to 20.
