Ensure precise and reliable water level management with this compact Water Level Controller Module, designed to automate water pump operation efficiently. Crafted with a durable PCB material, this controller offers simple wiring, low power consumption, and strong anti-interference capabilities, making it an ideal choice for household water tank and pool water level control. Key Features: · Compact and User-Friendly Design: Small-sized module with straightforward wiring, enabling easy installation and integration into existing systems without complexity. · Wide Operating Voltage: Supports a 9V-12V power supply, providing stable functionality while maintaining low power consumption for energy efficiency. · Automated Water Pump Control: Automatically activates the water pump when water levels are low and stops it once the tank or pool reaches full capacity, preventing dry-run and overflow situations. · Flexible Probe Replacement: Household wires can be used directly as probes, eliminating the need for purchasing separate sensors; bare wires serve as effective water level detectors. · High Current Relays with Strong Stability: Capable of controlling currents up to 10A, featuring a reliable relay switching mechanism that responds to water detection by probes at upper, middle, and lower positions. · Intelligent Working Principle: The relay closes when any two of the three probes (upper, middle, lower) are not immersed in water, activating the pump; the relay disconnects when all three probes are submerged, stopping the pump automatically for optimal water management. Specifications: · Material: PCB · Item Type: Water Level Controller Module · Power Supply Voltage: 9V-12V · Control Output Current: 0-10A · Working Principle: Relay closes with two probes out of water; relay opens when all three probes are submerged. Package Includes: · 1 x Water Level Controller Module This Water Level Controller Module is designed to provide an efficient and practical solution for automatic water level control, protecting your water pump and ensuring consistent water supply management for pools, water towers, and other household water storage systems.
