14. 14 Conclusion In conclusion, the water level indicator based on the 74LS04 IC and associated components presents a practical solution for monitoring water levels in various settings. While this system offers simplicity, cost-effectiveness, and ease of integration, it is important to acknowledge certain limitations. The single-point measurement and potential inaccuracies due to sensor placement, calibration, and environmental factors highlight areas for improvement. However, by implementing recommended enhancements, such as multiple sensors, advanced calibration techniques, and smart system integration, these limitations can be mitigated.
