The system consists of the IoT4H2O® data transmitter, the bracket / ground spike and a 4-fold ground temperature sensor that measures 0cm / 5cm / 20cm and 40cm under the dam crest.
The IoT4H2O® data transmitter (read: “IoT for water”) records the data from the floor temperature sensor and uses the NB IoT technology to transfer this data to our data cloud www.spargeltemperatur.de.
The four temperature measured values are displayed individually and the temperature sum is calculated based on the measured value at a depth of 20 cm.
Important functions for system administration, such as the option to name the stations specifically for the location or to set up sub-user accounts, are of course also available.
The data is available via a web app for computers and smartphones. In 2021, data hosting and use of the data interface www.spargeltemperature.de will be free.
IoT4Spargel can be used in the following countries (as of autumn 2020):
Germany, Austria, Hungary, Italy, Netherlands, Spain, Greece, Ireland, Portugal, Czech Republic, Slovakia, Romania, United Kingdom (UK).
