A Dual Sensor System for Determining the Unique Oxygen Production Signature of Plants
نویسنده
چکیده
Low cost sensor technology has made real-time monitoring of oxygen production and consumption from plants practical and affordable in homes. We describe an automated sensor based monitoring system comprising an oxygen sensor, a light sensor, and an automated data logging program that together enable near real-time measurement of oxygen production from common house plants. The results from the using system on common houseplants show that each plant has a very unique pattern of oxygen production during the course of a day. Even though light is critical for photosynthesis, all plants that were tested maximize their oxygen production during early morning hours, much before sunlight reaches its maximum intensity. Further, some plants tested here are net consumers of oxygen during a 24 hour cycle, as they consume more in respiration than they produce in photosynthesis. There are several practical applications from results observed with this monitoring system and interesting areas for future research. These include creating oxygen neutral smart homes, design of enclosed spaces for space travel, and deeper scientific understanding of the role that specific plants play in oxygen production, which has applications for wellness and prevention of diseases.
