Wireless Water Leak Sensors, Valves and Monitoring Software

Sensor types

• Spot leak sensors. Small, battery-powered sensors that sit on the floor beside a tank, pump, valve or drain. They trip when water touches their probes.
• Leak detection cable. A rope-style sensor that runs along a wall, under a row of equipment or around a room. It detects water anywhere along its length, so one cable covers what would take many spot sensors.
• Humidity sensors. Track moisture in the air, which can point to a slow, hidden leak in a closed room.
• Temperature sensors. Track room temperature, so a mechanical room or riser heading toward freezing gets flagged before pipes burst.

Typical sensor placement

• Spot sensors beside hot water tanks, boilers, pumps, backflow preventers and sprinkler valves.
• Leak cables along the base of mechanical room walls, under server racks and around floor drains.
• Humidity sensors in closed rooms, risers and storage areas where a slow leak could go unseen.
• Temperature sensors in parkades, risers and unheated rooms where pipes could freeze.
• Valves on the main supply or on branch lines feeding high-risk equipment.

Detection threshold and alerting

Our leak sensors detect as little as 0.5 mm of water. That's a thin film on the floor, well before a puddle spreads.

When a sensor trips, it sends a message over the wireless network to a gateway, and the gateway passes the alert to our Richmond command centre. Each sensor has a name and location, such as "P2 mechanical room, hot water tank 1", so the operator knows exactly where to look. Humidity and temperature sensors alert on limits we set for each room.

Automatic shut-off valves

A motorized shut-off valve fits on the water line feeding a building, a floor or a single piece of equipment. When a linked sensor detects a leak, the valve closes automatically and cuts the water supply. Valves can also be closed or opened on command.

Wireless connectivity, gateways and battery life

The sensors use LoRaWAN, a long-range, low-power wireless network built for sensors. LoRaWAN signals travel through concrete floors and walls better than Wi-Fi, which suits parkades, mechanical rooms and risers. The sensors don't need building Wi-Fi or new wiring.

• Sensors are wireless and battery-powered, so they go almost anywhere.
• Gateways collect signals from the sensors and send them to our system over the internet.
• Battery levels are reported by each sensor, and low batteries are flagged before they run out.

Camera verification

Each sensor is linked to the nearest camera. When a sensor trips, the operator gets the alert and the live view from that camera together. They can see whether water is spraying from a pipe, pooling under a tank or just a spill from a mop bucket. Where there's no camera in the room, the operator works from the sensor data and your instructions.

Dashboard, logs and reports

• Live status for every sensor: dry, wet, battery level, humidity and temperature.
• Event history with time stamps for every alert, valve action and operator action.
• Incident reports with operator notes and video where a camera covers the area.

System health checks watch sensors and gateways, so a device that stops reporting gets flagged.
