12V Liquid Level Controller and Water Detection Switch Module

This 12V liquid level controller module provides automated pump switching based on water level detection. It automatically activates pumps when levels drop and turns them off once full, making it ideal for hobbyists, makers, and DIY automation projects. Simple standard household wiring can be used directly as sensing probes without requiring specialised sensor hardware.

Automated water level control

The module uses an onboard high-current relay to automatically start pumping when liquid levels require replenishment and stop once full. It offers strong anti-interference capabilities, high stability, and low power consumption.

Versatile DIY probe compatibility

Dedicated probes are not required because standard household wire stripped bare by approximately 7 cm functions directly as an induction probe. Please note that cables and probes are not included in the package.

Practical applications

This controller is suitable for water tower tanks, pond management, garage flood prevention, and basement automated rain drainage systems.
