Heiman smart water leakage sensor HS2WL-M

The HS2WL-M is a compact, floor-level leak detector designed to quietly monitor vulnerable areas like under sinks, near washing machines, or in basements. Its core strength is simplicity: two exposed sensing probes at the base detect even small amounts of water, triggering alerts before a minor drip turns into serious damage.

Unlike bulky monitoring systems, this sensor is built as a small, sealed unit that can sit directly on the floor without drawing attention. It’s engineered for high-humidity environments, so it continues working reliably in places like bathrooms or utility rooms where condensation might affect other electronics.

An onboard buzzer and flashing indicator provide immediate local alerts, so even without a phone, you’ll know something is wrong.
