ToltHawk devices are a low cost, self-contained, wireless sensors for real time monitoring of floods, streams, rivers, lakes, sewer lines, and sewer lift pump stations. Our sensors are easy to deploy in the field and send data via cellular network or LoRA. Data is available via smart phone, web, local download, or API. Threshold alerts and smart analysis can help you keep an eye on floods or sewer infiltration and inflow issues. Have a custom requirement or idea? Talk to us.

What makes us different? Our solution is designed for easy installation and use, yet powerful, rugged, and low cost.

Hardware is Plug & Play, can be installed by a lay person, with no wires to pull, nor any calibration required. All configuration is online and can be done after installation, from the convenience of your desk.

Phone/Web App is easy to use and understand for the general public. Our online administrator tools are powerful, giving you unlimited control over the functionality of your devices , users and web and phone interface. This eliminates the need for you to hire web programmers and engineers.

Solution Customization: Our standard applications covers most of our customers cases. However if you need customization we may be able to do it either free or a small surcharge. We also have an extensive API which allows you to build your own interface inhouse. In any case, we can work with you whichever customization path you choose.


What Can ToltHawk Do?

  • Sensors: water level, depth, temperature, traffic vibration, and tilt alarm. Addition add-on sensors include: rain bucket, external temperature and humidity, wind anemometer, soil moisture, LiDar depth sensor, pressure transducer, and many more.
  • Web: Easy to understand web/phone application gives you a geographic dashboard view of all locations statuses in one place. You can also further drill down for detailed information for each location.
  • Text and Email Notifications: You can get notifications via text or email when certain thresholds are reached. For example you can set notifications for different levels of water under a bridge or a road.

How Is Data Sent?

  • Wireless:
    • Cellular: LTE, CAT M1, NB-IoT, 2G (auto switchable)
      • Auto switched for the best network. In US AT&T, Verizon, T-Mobile are supported
    • LoRa
  • (see LoRa vs Cellular)

Typical applications:

  • Monitoring rivers & streams,
  • Flood monitoring,
