Phyn’s Smart Water Sensor, available in one, two and three packs, safeguards homes against water damage by detecting leaks, changes in temperatures and potentially damaging humidity levels. The sensor can be placed throughout a home and immediately alerts homeowners the moment an issue is detected, serving as an extra layer of protection. It is ideal for hard-to-reach, leak-prone areas, the company notes, and can combat such problems as overflowing washing machines, leaking refrigerators, water heaters or sump pumps and flooded basements. Can be paired with the Phyn Plus to activate the shutoff valve feature and turn off water to the house.
