We have the new Minew MSL01 water leak sensor in stock.
The two probes are positioned vertically where there’s the possibility of a water leak. Special Bluetooth advertising is sent every second, by default, indicating whether there is a water leak or not, together with the battery level. There’s also an external on-off switch on the back.
The advertising can be picked up by a gateway or detected by scanning for Bluetooth on iOS and Android. The replaceable battery lasts up to 5 years at the default Bluetooth advertising frequency.
