A cheap toolkit built from off the shelf parts can now identify how a plant breathes.
Identifying whether a plant uses C3 or CAM photosynthesis usually involves complex isotope analysis and expensive gas exchange systems. This frugal sensing kit uses basic CO2 sensors and simple microcontrollers to achieve the same results in the field. It allows students and amateur explorers to map the metabolic pathways of plants in real-time. This democratization of science means that vital data on how crops respond to climate change can be collected by anyone with fifty dollars. Moving plant physiology out of the lab and into the backyard changes the way we monitor the health of the planet's vegetation.

Rapid environmental change and advances in data-driven analysis highlight the need not only to use computational tools, but also to foster understanding of the natural world and inspire creativity. Photosynthesis, the process that fuels nearly all life on Earth, provides a compelling context for such learning, particularly in understanding how plants alter their photosynthetic strategies in response to environmental changes. However, existing tools for studying photosynthesis are often inaccessi
