Description
Infrared dual-level water sensor module with two detection probes, high accuracy and stable performance.Sensor probes adopt full-sealed waterproof design, durable and practical.Can be used for laboratory, automatic water filling system of fish tank, general industrial site water level control, and other situations where water level control and protection are required.Output mode: relay switch output; Withstand current: 30A; Working voltage: AC 85-265V; Working current: Max. 100mA.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, D4 light off at the same time, D1 lights off and relay stops working
