Area of Science:

• Engineering
• Environmental Science
• Computer Science

Background:

• Many projects utilize Arduino Mega 2560 for single-purpose data loggers.
• There is a need for adaptable, low-cost hardware in scientific data acquisition.

Purpose of the Study:

• To demonstrate the application of a multi-purpose, low-cost data logger built with an Arduino Mega 2560.
• To propose an assessment framework for in-house developed low-cost scientific devices.

Main Methods:

• Developed a general-purpose data logger with flexible hardware and software architecture.
• Conducted short-term monitoring campaigns in diverse domains: air quality, office activity, cycling motion, and generator exhaust.
• Established an assessment process using development experiences and campaign data.

Main Results:

• The multi-purpose data logger demonstrated wide applicability across various monitoring scenarios.
• The proposed assessment framework evaluated the credibility of the low-cost device.
• The system scored well on product targets, but long-term stability was impacted by unexpected events.

Conclusions:

• Low-cost scientific devices require continuous evaluation and engineering corrections for long-term stability.
• Developing reliable in-house scientific devices presents challenges beyond initial expectations.
• The Arduino-based data logger offers a cost-effective solution for diverse, short-term scientific monitoring needs.
