Serelis — Early flood alerts to protect basements and equipment WiFi Leak Detector

WiFi leak detector — Overview

The WiFi leak detector uses an electrode water-sense detection method to recognise the presence of standing water and provide an audible alarm. This sensor is designed with rust-resistant probe elements, low power consumption and stable long-term performance. The device is intended to be placed on the ground where water intrusion or overflow is most likely to first appear — basements, computer rooms, storage areas and around equipment that must be kept dry.

Key features

• Detection method: electrode water sense detection for reliable contact-based sensing.
• Rust-resistant sensor: probe elements are designed to reduce corrosion and maintain sensitivity over time.
• Low standby power: quiescent current ≤20 μA helps preserve battery life when idle.
• Alarm current: ≤125 mA during active alarm output.
• Battery power: DC 3V via CR123A cell (user-supplied).
• Network: compatible with 802.11b/g/n WiFi networks (2.4 GHz/legacy 802.11 support).
• Compact size: 54 × 34 mm footprint makes it easy to position at likely leak points.

Installation & placement

Place the unit directly on the floor at the lowest, most leak-prone position you want to monitor. Because the device uses electrode contacts to detect water, ensure the sensing face or probe area is exposed to where water would first accumulate. Avoid placing the detector where heavy foot traffic or frequent movement could damage the probe. The compact footprint allows positioning along walls, beneath appliances, near drains, or under shelving where pooling can occur.

Power & maintenance

This WiFi leak detector is powered by a single CR123A battery (3V). With a quiescent current rated at ≤20 μA it is optimised for low standby consumption; alarm operation draws up to ≤125 mA. Replace the battery when the device indicates low voltage (threshold ≤2.6 V) or as part of a regular maintenance schedule. Periodically inspect the rust-resistant probe area for heavy deposits or debris and clean gently to preserve sensitivity.

Typical use cases

• Basements and crawlspaces — early detection of seepage or basement overflow.
• Server rooms and network closets — protect equipment by placing units near floor drains and under racks.
• Storage rooms and warehouses — monitor for roof leaks or plumbing failures.
• Under appliances — washing machines, water heaters, dishwashers and utility sinks.

Practical notes and compatibility

The device supports 802.11 b/g/n WiFi networks; as such it must be configured on a compatible network to take advantage of any networked integrations available for your setup. The detector is supplied as a floor-mounted alarm unit — follow local guidelines when locating devices and verify network requirements before deployment. When selecting a monitoring location, choose a point where water is most likely to reach the electrodes but where accidental splashes or routine floor cleaning won’t cause repeated false triggers.

Choosing the right detector

When choosing a WiFi leak detector, prioritise proven electrode sensing for early contact detection, low standby current for long battery life, and rust-resistant probes for durability in humid locations. The compact dimensions (54 × 34 mm) and simple placement method make this model suitable for targeted protection of vulnerable floor-level areas.

Note: This product is supplied as a network-capable alarm unit with the technical specifications listed above. For integration details specific to any smart-home platform or cloud service, consult the setup instructions that accompany the unit or the app/ platform documentation for the optional variant you choose.
