The 7Semi SCD40 CO2 Sensor Breakout is a versatile tool for developers, engineers, and hobbyists seeking a reliable and accurate solution for measuring CO2, temperature, and humidity.
CO2 Sensor or Carbon Dioxide Sensor : A CO2 sensor / carbon dioxide sensor is a device used to measure the concentration of carbon dioxide (CO2) in the air. These sensors use various technologies, including infrared sensing and electrochemical detection, to detect and measure the levels of CO2 in the atmosphere. CO2 sensors / carbon dioxide sensors are commonly used in a wide range of applications, including indoor air quality monitoring, HVAC systems, and environmental monitoring. They are also used in industries such as agriculture, healthcare, and automotive to monitor and control CO2 levels. CO2 sensors / carbon dioxide sensors are important tools for ensuring the health and safety of individuals and the environment, as well as for improving energy efficiency and reducing carbon emissions.
