ToltHawk Sensors
ToltHawk Cloud Device is a compact, multi-sensor unit built for field monitoring, with radar as the core technology for measuring water level and flow velocity.
Our sensors are known for their reliability, ultra-long life, precision, compact size, low-cost, and its self contained design with no wires to connect and very low maintenance requirement. They are extremely easy to install.
Core data — including water level, temperature, rainfall, and onboard camera images — is captured at regular intervals, then wirelessly uploaded to ToltHawk Cloud for viewing in a clear, browser-friendly dashboard or mobile interface. Advanced processing layers apply targeted analytics and visualization pipelines shaped to each customer’s monitoring goals and operational needs.
