CO2Melder

CO2Melder is a community-driven project focused on measuring and visualizing indoor air quality, specifically carbon dioxide (CO2) levels. The project aims to make CO2 monitoring accessible and understandable for individuals and organizations. By deploying simple, low-cost sensors, CO2Melder collects data on CO2 concentrations within various indoor spaces, such as homes, schools, and offices.

The primary goal of CO2Melder is to raise awareness about the impact of indoor air quality on well-being and cognitive function. Elevated CO2 levels, often caused by poor ventilation and a high occupancy of people, can lead to symptoms like fatigue, headaches, and reduced concentration. CO2Melder provides real-time data, often displayed on public dashboards or through personal devices, allowing users to identify poorly ventilated areas and take action.

The project typically utilizes readily available hardware components and open-source software, fostering transparency and encouraging wider adoption. Participants can contribute data from their own sensors, creating a decentralized network of air quality information. This collective data can then be analyzed to identify patterns and inform public health initiatives. CO2Melder emphasizes the importance of ventilation as a simple yet effective measure to improve indoor air quality and enhance the health and productivity of occupants.
