Raspberry Pi-powered temperature monitoring of growth chamber microclimates

Area of Science:

• Plant Science
• Environmental Monitoring
• Agricultural Technology

Background:

• Controlled environments like growth chambers are crucial for plant research but suffer from microclimates and temperature fluctuations due to door openings.
• Existing methods for normalizing temperature data, such as using multiple data loggers, are often expensive and lack real-time feedback.

Purpose of the Study:

• To develop a low-cost, automated system for monitoring and managing microclimates within plant growth chambers.
• To enable real-time temperature data acquisition for normalizing plant growth and stress response measurements.

Main Methods:

• Utilized low-cost single-board computers, cameras, and temperature sensors for integrated environmental monitoring and plant imaging.
• Developed methods to document microclimates within a growth chamber for subsequent data normalization.

Main Results:

• Successfully implemented a system for automated temperature monitoring alongside plant image data acquisition.
• Demonstrated the capability to document microclimates for normalizing experimental results.

Conclusions:

• Presents a cost-effective protocol for automated temperature monitoring in controlled plant growth environments.
• Facilitates high-throughput measurements of both temperature and plant responses, including growth and stress, through integrated imaging.
