I’ve developed and built a measurement station to measure the water temperatures of the lake Kreidesee Hemmoor. It measures in different depths up to 50m. You can find the measurement-page with live-data here: tms.dive3d.eu
And my 3D-models of the UW-objects here: Hemmoor

Temperature vs depth

The electronic

It is an own development. The sensors (Dallas 1-wire bus) are connected in a bus system and read out by the microcontroller. The data is sent by a GSM modem using SMS. At home my server receives the SMS by an other GSM modem which processes the data and sends it to my website: tms.dive3d.eu

Testing and calibration

I tested and calibrated each sensor in ice-water, because ice-water has a temperature of exactly zero degree Celsius.

Installation

Lars Konrad and I installed the measurement system in April 2024
