Establishment of a low-cost photosynthesis measurement system based on a single-board microcomputer and CO₂ sensors.

ABSTRACT: Leaf photosynthetic rate serves as a growth indicator in plant science; however, the high cost (exceeding USD 70,000) of traditional measurement system is the main concern when making photosynthesis measurements of interest to a wide range of users. Recently, the availability of inexpensive environmental sensors and single-board microcomputers has increased substantially. In this study, we selected CO₂ sensors based on a comparative analysis of four cost-effective sensors. The economical K30 sensor demonstrated a superior response to CO₂ fluctuations, compared to the other tested low-cost sensors, and exhibited noise-free stability relative to the values recorded by the high-precision system (LI-850). A closed-chamber system was constructed, incorporating the K30 sens
