Liquid Level Detection with Camera and YOLO
lukas_m_ziegler · x · 2026-07-17
The author built a low-cost liquid level sensor using a camera and Python for bottle liquid recognition, rather than relying on specialized hardware.
Implementation steps include:
- Real-time camera observation of the bottle
- Using YOLO to detect the target bottle
- Applying HSV color analysis to read liquid height
- Angle correction to handle tilted containers on conveyor belts
The author highlights that this approach is highly suitable for automation retrofits while keeping costs manageable.
