Wireless Sensor Data Logger

Project Overview

Measure and store environmental readings with timestamps for offline analysis.

Objectives & Learning Outcomes

RTC timekeeping, CSV writing, buffer control and wear awareness

Required Hardware

ESP32, BME280, microSD module, RTC, battery supply

Suggested Build Stages

1. Review the components and create a low-voltage wiring plan.
2. Assemble the prototype and test each sensor or module individually.
3. Implement firmware, display or communications in small verified steps.
4. Integrate the modules and document operating states and failures.
5. Run validation tests and prepare demonstration documentation.

Testing & Validation

Inspect logged values after disconnections, low power and restarts.

Suggested Deliverables

Working demonstration, wiring diagram, commented firmware, test observations, component list, project report outline and presentation outline.

Educational project concept. Verify circuit values, actual component compatibility and safe operating limits before assembly. Illustrations are representative, not exact build photographs.
