CO2 sensor "STCC4"

The smart thermostat provides a comfortable environment by monitoring and controlling indoor temperature, humidity, and CO₂ concentration, and optimizes energy consumption using geofencing (automatic control based on location) and advanced algorithms. It can also be integrated with smart home ecosystems such as heat pumps, HVAC systems, and heat exchange ventilation systems. ■ Recommended Sensors Humidity and Temperature Sensor SHT40: High precision of ±1.8% RH and ±0.2°C. Size: 1.5×1.5×0.5mm CO₂ Sensor STCC4: Current consumption of 850μA (at 1Hz operation). Size: 4×3×1.2mm ■ Sensirion's Solutions - Industry-leading compact humidity, temperature, and CO₂ sensors - High precision and high reliability - Sensor variations according to application and budget - Sensors compliant with WELL, RESET, CA24, USGBC, ASHRAE standards ■ Recommended Applications - Smart thermostat - Indoor air quality monitor - Smart speakers - Wearable devices - Air purifiers For product specifications or inquiries, please contact us or use the document download option.

Sensirion has started selling the "STCC4". The world's smallest CO₂ gas concentration sensor Overcoming size and cost constraints, it enables CO₂ measurement across a wide range of applications. ■ Thermal conductivity sensing technology ■ By collaborating with Sensirion's temperature and humidity sensors, it allows for: - High-precision correction of measurement values - Monitoring of indoor environmental parameters ■ SMD design and tape & reel packaging support mass production ■ Ideal for integration into indoor air quality monitors, smart thermostats, air conditioners, and more.

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. At this exhibition, in addition to environmental sensing and flow sensing, we will also introduce sensor solutions for automotive applications. We will showcase measurement demos and new products that will be publicly unveiled for the first time, providing an opportunity for you to directly confirm the performance and high level of our technology. We look forward to your visit. ■ Venue: Tokyo Big Sight ■ Booth No.: E - 8 (East Hall 8) ■ Exhibits: SEN6x Indoor Air Quality Combo Sensor Module Measurement Demo SGD4x Refrigerant Detection Sensor Measurement Demo SCD4x/STCC4 CO2 Sensor Measurement Demo SLF3x Liquid Flow Sensor Measurement Demo Fog Detection/Automatic Defrost Sensor Measurement Demo Various Physical Samples All of our staff are sincerely looking forward to your visit.
