Apollo SEN55 and SCD40 Breakout Board with Stemma QT Connectors NDIR CO2 Sensor, VOC, PM1, PM2.5, PM4, PM10, NOx, Temperature & Humidity Air Quality, Smart Home & IoT Projects (No SCD40 CO2 Sensor)

The Apollo Automation SEN55 and SCD40 Breakout Board is a powerful and versatile environmental monitoring solution designed for smart home enthusiasts, developers, researchers, and educators. This breakout board integrates two of the most advanced sensors for indoor air quality measurement: the SEN55 environmental sensor and the SCD40 CO2 sensor. Together, these sensors provide precise, real-time data on temperature, humidity, volatile organic compounds (VOCs), and carbon dioxide (CO2) levels, essential for maintaining healthy indoor environments and optimizing HVAC systems. Featuring dual STEMMA QT connectors for seamless plug-and-play integration and standard header holes for flexible soldering or breadboard prototyping, the board offers maximum compatibility with popular microcontrollers and IoT development platforms. Its compact and lightweight design makes it ideal for rapid prototyping, embedded system projects, and scalable smart home solutions. The SEN55 sensor is capable of measuring fine particulate matter (PM1, PM 2.5, PM4, PM10), VOCs, temperature, humidity, and nitrogen oxides (NOx), while the SCD40 sensor uses non-dispersive infrared (NDIR) technology to deliver highly accurate CO2 readings. This combination ensures comprehensive air quality monitoring that supports automated ventilation, air purification, and greenhouse climate control. Fully compatible with Apollo Automations DEV-1 and DEV-2 development boards, this breakout board simplifies the integration process for both beginners and advanced users. Whether you are building an advanced air quality monitoring system, developing smart home automation workflows with Home Assistant or Homey, or conducting scientific environmental research, the Apollo SEN55 and SCD40 Breakout Board provides a reliable and easy-to-use foundation.

Key features include true NDIR CO2 sensing, multi-pollutant VOC detection, particulate matter measurement, and precise temperature and humidity monitoring. Its STEMMA QT connectors enable quick sensor swaps and expansions, while the standard headers allow for customization and integration into diverse hardware projects. Optimize your indoor air quality management, improve energy efficiency, and create healthier living and working spaces with Apollo Automations SEN55 and SCD40 Breakout Board. This is the ideal choice for environmental sensing, smart homes, IoT development, greenhouse monitoring, and educational applications.
