This water leak detector is a smart little safety device that can save you from a flooded basement or burst pipe.
It works by measuring conductivity – as soon as the metal probes touch water, the circuit closes and triggers the relay.
You get both NC and NO outputs (max load 260V 10A), so you can hook it up to a shut-off valve, a siren, or pretty much any other device you want to control when water is detected.
The sensitivity is adjustable, so you can dial it in to avoid false alarms or missed detections.
Built-in buzzer hits 80 dB – loud enough to get your attention – and you can turn it on or off as needed.
