HANDS-ON STEAM PROJECT
Water Tank Overflow Alert
Prototype a water-level alarm with isolated low-voltage electronics.
Instructions and Learning Resources
Concept
A water-level sensor can signal when water reaches a selected threshold.
Parts
Compatible sensor, controller or comparator, buzzer or LED and low-voltage source.
Steps
- Choose a sensor designed for the liquid and mounting conditions.
- Calibrate empty and full readings.
- Turn on the indicator when the selected level is reached.
- Keep circuitry in a splash-protected enclosure.
This demonstration must not be connected directly to mains-powered pumps.
