Water temperature monitor

Live water temperature readings from our local pier, published online and available as a phone app.

The pier with the solar-powered sensor
The transmitter on the pier

I built this system to publish live water temperature readings from our local pier. A transmitter on the pier, powered by a small solar panel and a battery, sends the measurements wirelessly to a receiver at another location.

The receiver is connected to the internet and publishes the readings to a website that can be installed on a phone as an app for quick access. It shows the current temperature together with graphs and statistics for the last days.

Adaptable by design

The system can be adapted to almost any sensor, measure almost anything, and publish the data almost anywhere. See it in action at www.aashansen.no/vallo.

Custom versions can be built on request, on agreed terms. Please use the contact form for enquiries.
