Another smart sensor from AQARA that provides timely response to water leakage incidents. The sensor is protected by an IP67 certificate, through which it is completely protected from water and dust. The smart sensor works on a C-type 2032 size cell, which provides up to 2 years of operation on average. The device automatically sends a signal when the water level on the floor reaches 0.5mm. The smart sensor requires AQARA Hub E1 to work.
