The Wireless Sonar SenSpot™ is a high-performance solution for collecting underwater data, such as depth and water temperature. This wireless sonar sensor is easy to install and scalable, featuring a high-capacity lithium-ion battery and solar panel mount, eliminating the need for battery replacement. With IP67 protection, it is completely weatherproof, making it ideal for marine applications in hard-to-access locations.
The sonar transducer uses an AIRMAR EchoRange™ 200KHz sensor, renowned for its accuracy in measuring underwater depth and temperature. Resensys proprietary wireless technology ensures efficient large-scale sensing, wireless synchronization, and ultra-energy-efficient communication in the Wireless Sonar SenSpot™.
Additionally, the Wireless Sonar SenSpot™ can function as a repeater, extending the communication range between other SenSpot™ sensors and their SeniMax™ datalogger.

A wireless sonar sensor is a device used to measure underwater distance, sediment levels, or water depth using sound waves. It transmits acoustic signals toward the surface or riverbed and calculates the distance based on the returning echo, sending the data wirelessly to a monitoring system.
Wireless sonar sensors are typically installed in rivers, reservoirs, dams, canals, and marine structural health monitoring system. They help monitor underwater conditions and provide critical data for water resource management and infrastructure protection.
Underwater monitoring helps engineers understand changes in water depth, sediment movement, and riverbed conditions. Using a wireless sonar sensor, engineers can detect changes that may affect bridges, dams, or other hydraulic structures.
Wireless sonar monitoring systems eliminate the need for extensive cabling in water environments. They allow sensors to transmit real-time underwater measurements remotely, enabling efficient monitoring across large water bodies and remote locations.
