News Summary
SpecFive, a technology company from Austin, Texas, has launched a flood warning system following the deadly floods of July. The system utilizes float sensors connected to solar-powered modules to provide early alerts, ensuring communities, especially those in remote areas, are better prepared for flooding events. By employing LoRa technology, the solution allows for extensive coverage without reliance on cellular networks, making it a potentially lifesaving investment for vulnerable regions.
Austin, Texas – SpecFive, a technology company based in Austin, Texas, is addressing flood safety after deadly floods this past July. The floods highlighted the need for a faster, more effective warning system for communities, especially in remote areas with unreliable cell service.
To demonstrate their flood warning system, SpecFive created a simulated river on their ranch in Florence, Texas. This system is designed to provide critical time during disasters by utilizing float sensors connected to solar-powered radio modules placed miles upstream along rivers and creeks. The sensors activate a digital tripwire that sends alerts downstream when water levels rise, providing early warnings to residents.
When alerts are triggered, loud sirens and dedicated radios installed in homes, cabins, and campgrounds alert residents well before floods reach them. The devices can be spaced every 5 to 10 miles based on the topography of the area, allowing extensive reach across vulnerable regions.
Crucially, SpecFive’s technology operates independently of both cellular and internet networks, which can often fail during disasters. By employing LoRa technology, a long-range radio protocol similar to a digital version of a CB radio, the system can send alerts over considerable distances without the need for cell towers. This ensures that all citizens receive the same warning messages as first responders without delay.
The cost for each flood sensor and relay unit is approximately $2,000. To achieve extensive coverage of rivers, the estimated investment ranges between $20,000 to $30,000, with no ongoing monthly fees associated with the system.
SpecFive’s overarching goal is to create a statewide network of sensors to enhance proactive flood safety measures across Texas. The company envisions a “digital safety embrace” for Texas through its sensor network, particularly targeting areas most vulnerable to flooding, where help is often distant.
Background on July Floods
This past July, Texas experienced deadly floods that underscored the critical need for improved disaster preparedness systems. Several communities found themselves ill-prepared and unable to receive timely warnings, prompting SpecFive to develop this innovative technology to enhance safety across the state.
