Infrared Dual Level Liquid Water Sensor Module Relay Switch Output 30A Detection Probes for Automatic Fish Tank Filling System and Industrial Site Control

[DUAL LEVEL INFRARED DETECTION] This advanced water sensor module features two infrared detection probes for precise liquid level monitoring. The intelligent dual-level system provides accurate water level detection with instant response, making it ideal for critical applications where reliable liquid monitoring is essential.[FULLY DESIGN] Engineered with a completely sealed construction, our sensor probes can withstand continuous submersion without compromise. The robust design ensures long-term durability even in harsh environments, offering reliable performance in both industrial and residential settings.[HIGH POWER RELAY OUTPUT] Equipped with a heavy-duty 30A relay switch output, this module can control powerful external loads with ease. The clearly visible status indicators (D1, D3, D4) provide instant visual feedback on operation status, while the NO and COM connections enable seamless integration with your existing systems.[INSTANT RESPONSE OPERATION] When both liquid level indicators activate simultaneously, the relay immediately engages to power connected equipment. The system responds with speed to changing water levels, ensuring timely activation or shutdown of pumps and other devices as needed for optimal control.[VERSATILE APPLICATION RANGE] for laboratory use, automated fish tank systems, and industrial water management. This sensor provides reliable level control for both protection and automation purposes, suitable for diverse environments from home aquariums to large-scale industrial facilities.Spec:Features:This is a infrared dual-level water sensor module with two detection probes.Sensor probes adopt full-sealed design.Output mode is relay switch output, withstand current is 30A.When liquid level state indicators (D3, D4) light on at the same time, relay status indicator (D1) lights on and relay start to work. NO and COM are connected and external load starts to work. When D3,
