Water Leak Sensors
Early Detection For Preventing Water Damage & Protecting Your Home
Water leak sensors sit near appliances, pipes, and other moisture-prone areas to alert your smart home system when water is detected. Many sensors use exposed probes or fully sealed detection pads to sense moisture, triggering notifications, alarms, or automated shutoff routines.
Their compact design, simple placement, and long battery life make them a reliable part of home safety planning. When connected through your smart home platform, leak sensors play a major role in preventing water-related damage before it worsens.
Instant Water Detection Alerts
Sensors identify water the moment it reaches the probes or sensing surface, helping you react quickly to leaks, overflows, or unexpected moisture.
Flexible Placement In High-Risk Areas
Leak sensors can be placed behind toilets, under sinks, near water heaters, beside washing machines, or along basement floors. Many include optional probe cables for extended reach.
Automation Support For Safety Routines
When water is detected, you can trigger actions such as shutting off valves, sending alerts, sounding alarms, or turning on sump pumps depending on your setup.
Low-Power Operation For Long Battery Life
Most leak sensors use efficient radios like Zigbee, Z-Wave, Thread, or Bluetooth, allowing years of battery life without frequent maintenance.
Designed For Home Safety & Prevention
By catching leaks early, these sensors help prevent mold, damaged flooring, electrical issues, and structural damage that can occur when water goes unnoticed.

Frequently Asked Questions
Where should I place water leak sensors?
Common locations include under sinks, behind toilets, near water heaters, next to washing machines, by sump pumps, and in basements or crawlspaces.
Do water leak sensors need a hub?
Many leak sensors use Zigbee, Z-Wave, or Thread and require a compatible hub or coordinator. Wi-Fi or Matter-over-Wi-Fi models may connect directly.
Can leak sensors shut off water automatically?
Yes. When paired with a compatible smart water valve controller, leak sensors can trigger shutoff routines to stop the flow of water when a leak is detected.
Are leak sensors waterproof?
Yes. Leak sensors are typically sealed or designed with moisture-resistant materials so they can safely detect water without damage.
How often do leak sensors need new batteries?
Most leak sensors last one to three years depending on the wireless protocol, usage, and environmental conditions.
