Water and flow sensors detect the presence of liquid, measure flow rate, and monitor liquid levels in tanks and containers. They are essential for any project involving fluid management, from automated plant watering to aquarium monitoring.
The range includes YF-S201 and FS400A water flow sensors for measuring volumetric flow rate, resistive and capacitive water level sensors, rain detection modules, and submersible liquid level probes for tank monitoring.
These sensors are used in Arduino plant watering automation, aquarium and pond management systems, smart irrigation controllers, rain-triggered window closers, water leak detection systems, hydroponics nutrient level monitoring, and STEM projects demonstrating fluid dynamics and level measurement principles.
