Harnessing data that utilizes the Internet of Things we identify and eliminate water waste on a massive scale, saving multi-unit property owners thousands in utility costs each month.

Sensor Industries

Our scalable suite of IoT solutions and technologies leverage real-time data to stop catastrophic floods and control water waste that tenants or hotel guests just don’t report.  

SI-Toilet Sensors

More than 20% of ALL TOILETS are leaking and they’re the #1 source of water waste for multi-unit property owners.*

Until now, there was no cost-effective solution to monitor and notify property owners of leak loss.

SI-Leak Sensors

A single undetected flood caused by leaking plumbing, hoses, or appliances can cause catastrophic damage and expenses ranging into the millions.*

The SI-Leak Sensor detects water waste emergencies and alerts you of a flood in real-time via text message.

The Wireless Mesh Network

Sensor Industries’ patent-pending proprietary wireless Mesh network is specifically designed to power a vast network of sensors that monitor and report on a wide array of environmental conditions and building performance systems.

Access to this vital data lowers costs, reduces risks, and provides new revenue opportunities for property owners.

SI-Sensors – How They Work

Easily inserted between the supply line and fill valve on any toilet, SI-Toilet Sensors monitor and report each time a toilet is flushed and water fills the tank. Our patent-pending sensor design is sleek yet durable and includes a micro-computer, radio board, reed switch and small magnet. When water flows into the toilet, the magnet is pushed up by water pressure – it then closes the reed switch and counts time. When the water stops, the magnet drops and the time packet is sent through the SI-Mesh network and up to our cloud servers for analysis. If a leak is detected, a real-time text message alert is sent to the building manager to minimize water waste and unnecessary water costs.

The SI-Flood Sensor installs with ease and security in any pain point area! We offer multiple varieties to capture any leak in any place! Utilizing the latest in water detection technology, the SI-Flood Sensor detects flowing or freestanding water and emits an alert to your email or phone within seconds giving you complete control and security over the health and status of your property.
