The annual subscription for the Tide Alerts™ service includes a free lease of the tide gauge during the subscription.
(Email us at sales@sentientthings.com for discounted subscriptions if you are an individual installing a tide gauge at your personal waterfront property)
The tide gauge is a solar powered sensor that sends range measurements to the Tide Alerts application using an integrated cellular modem. For tide measurements, the gauge is typically mounted on a piling, post, or walkway overhanging the water.
The annual Tide Alerts subscription includes:
Data publishing – your station’s tide data displayed on the Tide Alerts app.
Services – real‑time tide readings and tidal forecasts for stations with valid tidal data. Forecasts are generally available after at least 35 days of valid data collection.
By subscribing, you agree to the Tide Alerts Terms and Conditions of Service.
