Automatic Water Tank Level Controller

Project Overview

Detect water level and operate a low-voltage pump with dry-run safeguards.

Objectives & Learning Outcomes

Range conversion, hysteresis, state control and fault alerts

Required Hardware

ESP32 or Arduino, ultrasonic sensor, miniature pump, MOSFET driver

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

Test full/empty thresholds, sensor dropout and overflow override.

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.
