Semtech’s LoRa Technology and Senet’s LoRaWAN-based Network Leveraged in Flood Sensors to Monitor Water Levels

Green Stream’s IoT solution is designed for installation into complex, hard-to-reach or hard-to-cover regions

LOS ANGELES, at Mobile World Congress Americas, Sept. 12, 2018Semtech Corporation (Nasdaq: SMTC), a leading supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, announced that Green Stream, a leading environmental technologies firm helping to build safer, more resilient communities through the power of smart technology, has incorporated Semtech’s LoRa® devices and wireless radio frequency technology (LoRa Technology) and Senet’s LoRaWAN™-based network into its autonomous flood sensor systems for use in coastal areas including towns and cities.

“In many coastal towns and communities, rising water as a result of tides or rain can present a large threat,” said Jim Gray, CEO of Green Stream. “Semtech’s LoRa Technology and Senet’s network based on the LoRaWAN protocol offers a low cost, high tech approach to flood monitoring that wasn’t possible before. Each sensor can be deployed in hard-to-reach positions along the water’s edge in marshland, rough terrain or in residential neighborhoods lacking urban infrastructure.”

Green Stream’s solutions utilize LoRa Technology, a proven technology leader used in IoT environmental solutions. Green Stream’s end-to-end flood monitoring solutions are designed using commercial, off-the-shelf ultrasonic sensors and easy to deploy LoRa-enabled gateways. The data is communicated over a LoRaWAN-based network provided by Senet, a leading provider of Cloud-based LoRaWAN services platforms that enable the on-demand build out and management of IoT connectivity. The Green Stream LoRa-based flood sensors are autonomous, requiring no external power or wired network connection. Each sensor is a self-contained, weather-proof, solar-powered unit that comes with a universal mounting bracket and extension arm. These sensors are small enough to be installed on top of crosswalks, light or electric poles and bridges. The rugged sensor gateway is positioned above a body of water or over dry land.

“Environmental monitoring fits particularly well into the value proposition of the Internet of Things with sensor data being used to support mission critical applications that can have a significant impact on people’s safety and well-being”, said Bruce Chatterley, CEO at Senet. “LoRaWAN connectivity is perfectly suited for environmental monitoring, and we are excited to be working with Green Stream and Semtech to help create smarter, safer, more resilient communities.”

“IoT solutions are ideally equipped for potentially hazardous situations such as floods and other water-related disasters,” said Alistair Fulton, Vice President of Product Management for Semtech’s Wireless and Products Group. “Semtech’s LoRa Technology enables the next generation of IoT solutions without significant infrastructure investment and is a proven, easy-to-deploy platform.”
