I’ve built a measurement station to measure the temperatures in different depths up to 50m. You can find the measurement-page here: tms.dive3d.eu

Temperature vs depth

You can find some history data and graphs here: Link

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

Installation

Lars and I installed the measurement system in April 2024
