Plant transpiration sensor with light reminder system

Overview

This innovative plant care technology uses a sensor that detects when plants need water by measuring the amount of CO2 released during transpiration. When the sensor determines that the plant requires watering, it triggers a light to serve as a visual reminder. The technology addresses a common challenge for plant owners by providing an automated, biologically-driven approach to plant care monitoring. Future plans include developing a companion mobile application connected to the sensor system, creating a comprehensive plant care solution for both casual plant enthusiasts and serious growers.

Technical specifications

Key features:

• Transpiration-based detection: The sensor measures CO2 released by the plant during transpiration to assess water needs
• Light-triggered alert system: An integrated light activates when the plant requires watering, providing a clear visual reminder
• Biologically grounded sensing: Detection is based on the natural physiological process of transpiration rather than soil moisture alone
• Research-informed design: Developed with insights from plant studies conducted within a Mars analog habitat (SHEE habitat), providing data from controlled environment agriculture scenarios
• Future app integration: Planned development of a connected mobile application for remote monitoring and notifications

Technology readiness level

This technology is currently at an early research and concept validation stage. The researcher has conducted preliminary studies within a Mars analog habitat (SHEE habitat) to understand various plant methods and transpiration behaviors. Future validation efforts will focus on comparing leaf and root transpiration readings to determine which process provides the most accurate measurement of plant water needs, given that leaves are typically the first to dry during water loss. The technology is positioned as a potential spin-off product targeting plant enthusiasts, with ongoing development needed before commercial readiness.
