Water Level Controller Module AC 9-12V DC 12-15V 10A Auto Pump Tank Switch

💧 Water Level Automatic Controller — AC 9–12V / DC 12–15V 10A Liquid Control ModuleCompact automatic water level controller module designed to switch a compatible pump, solenoid valve, or other load when the liquid level reaches the configured points. This module is ideal for water tanks, aquariums, farm water systems, and other projects that require simple automatic refill or water exchange control using a conductive-liquid sensing method.It is a practical solution for users who need a compact board with 10A relay capacity, flexible AC or DC supply compatibility, and simple wiring using ordinary conductive probe wires.🔧 Key Features
⚡ Dual Supply Compatibility: works with DC 12–15V or AC 9–12V
🔌 10A Relay Output: suitable for switching compatible pumps, valves, and control loads
💧 Automatic Water Level Control: designed for refill, water-change, and liquid level automation tasks
🧪 Conductive Liquid Sensing: works with probe wires in conductive liquids
🏠 Simple Probe Concept: no special sensor is required; probe leads can be made from ordinary household wire
📐 Compact Module Size: easy to install in project boxes, utility cabinets, and DIY systems🧠 What This Module Is Best ForAutomatic Tank Refill
Use it when you want a pump or valve to help maintain water level automatically in a tank, tower, reservoir, or livestock watering setup.Aquarium / Fish Tank Water Change
Useful for simple automated liquid handling where the water level needs to be controlled within a set range.General Conductive Liquid Control

Need automatic refill in a tank or water tower? This module is a strong fit.
Need a simple aquarium or water-change controller? This board is commonly used for that type of task.
Need a dedicated waterproof sensor included? This is not that style — the package does not include probe wires.
Need a non-contact liquid sensor? Choose a different sensing technology instead.🧰 Typical Uses
Home water tower automatic supply systems
Aquarium and fish tank water changer systems
Conductive liquid automatic control
Poultry and livestock automatic feeding / watering systems
Farm automatic water supply systems
Solenoid valve, water pump, or motor control projects🔌 Wiring & Safety
Match the module to a suitable DC 12–15V or AC 9–12V power source.
The package does not include probe wires; probes can be made from ordinary household wire.
Use this module only in applications where the liquid is suitable for conductive probe sensing.
For best safety, use an AC/DC power supply with good isolation.
If switching motors, pumps, or other inductive loads, use proper suppression / protection as needed.
Always verify your load voltage and current before connecting the relay output.⚠️ Important Notes
This package does not contain the probe wire.
This module is intended for conductive liquid level control.
It is a controller board, not a complete pump or valve system.
Improper wiring, poor isolation, or overload conditions may damage the module or create a safety hazard.📦 Package Includes
