Remote Photoelectric Water Leak Sensor with Bracket Easy Installation

An optical water leak sensor is a device that detects the presence of water using infrared light instead of conductive probes. It monitors changes in light reflection caused by contact with liquid and sends an alarm signal when a leak is detected.

When light rays are emitted from the sensor probe and encounter the water surface, the light's propagation path changes, causing a change in the light signal received by the sensor. By monitoring this change, an optical water leak sensor can accurately determine the water level or whether a leak exists.

We offer two output options: RS485 and switch output. RS485 version wiring: Brown wire: Power positive (10~30 VDC) Black wire: Power negative Yellow wire: RS485-A Blue wire: RS485-B Switch output version wiring: Brown wire: Power positive (10~30 VDC) Black wire: Power negative Yellow wire and blue wire: Relay normally open (NO) contacts.

LED flashes once every 5 seconds: No liquid detected (dry condition) LED flashes rapidly: Liquid detected (leak condition) LED remains continuously on: Device fault or abnormal status

Single-point monitoring: The sensor data can be uploaded to the user's own software system through an RS485 to USB converter for viewing and analysis. Multi-point monitoring: Multiple sensors can be connected to our environmental monitoring host, which supports up to 32 monitoring channels. The host collects and uploads all data to our free cloud platform, allowing users to view real-time data from all monitoring points in a centralized interface.
