HC-SR501 Passive Infrared (PIR) Motion Sensor Detector Module-Pyroelectric Infrared Sensor-Pack of 1 AB0172

Application Ideas:

• Water Tank Monitoring: Keep track of water levels in tanks to avoid overflows or shortages.
• Aquarium Systems: Automate the water level control in aquariums for optimal fish care.
• Smart Irrigation Systems: Ensure water levels are properly maintained for efficient irrigation.
• Flood Warning Systems: Provide early warnings by detecting sudden water level changes in flood-prone areas.

How It Works:

The sensor typically uses probes or capacitive sensing technology to detect the water’s presence or depth. The sensor outputs a voltage or a signal corresponding to the water level, which is read and processed by the connected Arduino board. The Arduino then triggers corresponding actions, such as turning a pump on or off, sending notifications, or activating other systems.

This water level sensor is a cost-effective, reliable solution for various DIY and industrial water monitoring projects.
