The Water & Temperature Sensor is a sensor that helps detect potential leaks, flooding, and moisture buildup near common trouble spots like water heaters, washing machines, dishwashers, sinks, and basement floors. It can also help identify rapid temperature drops that may indicate frozen or burst pipes during cold weather. The sensor sends a real-time notification through the ADT+ app so you can take immediate action from virtually anywhere
The Water & Temperature Sensor includes easy installation. Mount it on a wall or place it on the ground near areas where you want to help detect water, such as near water heaters, washing machines, sinks, or basement floors. Visit our support article for step-by-step instructions.
Place the Water & Temperature Sensor near areas most prone to water damage or temperature extremes. Common locations include near water heaters, washing machines, dishwashers, sinks, basement floors, and laundry rooms. The sensor can be mounted on a wall or placed directly on the ground, depending on the area you want to monitor. Position it where water would collect first if a leak occurred.
The Water & Temperature Sensor detects water as soon as it contacts the device and sends a notification to your phone through the ADT+ app. Early detection is critical because water damage can escalate within minutes. A slow leak under a washing machine or water heater can go unnoticed for hours without a sensor in place. The notification can give you time to shut off the water supply, move valuables, or contact a plumber before a small leak becomes a major repair. The sensor monitors continuously, including when you are away from home or asleep.
The sensor helps detect potential leaks, flooding, and moisture buildup near common trouble spots like water heaters, washing machines, dishwashers, sinks, and basement floors. It can also identify rapid temperature drops that may indicate frozen or burst pipes during cold weather. Mount the sensor on a wall or place it directly on the ground near the water source you want to monitor. Because the device is battery-powered and wireless, you can position it in hard-to-reach areas like behind appliances or under sinks where leaks often start unnoticed.
Yes. When the sensor detects water or a rapid temperature change, it sends a real-time notification through the ADT+ app so you can take immediate action from virtually anywhere. The sensor connects to your system through your Base and requires a secure Wi-Fi network for app-based notifications. If you selected the Pro-Protect monthly monitoring plan with ADT 24/7 professional monitoring, the monitoring center can also be notified of the event.
Yes. The Water & Temperature Sensor includes temperature settings that let you detect if your home is getting too warm or too cold for your pets while you are away. You receive notifications through the ADT+ app when temperature conditions fall outside your configured range, allowing you to take action before conditions become unsafe.
The Water & Temperature Sensor is wireless and battery-powered, so it can continue to monitor locally during a power outage. Connected features like ADT+ app notifications require working internet and Wi-Fi.
