The multi-parameter IoT sensor is a mobile measuring device for liquid analysis. This enables the most varied of measurements to be carried out with the multi-parameter IoT sensor. With this multi-parameter IoT sensor, for example, it is possible to determine alkalinity, chlorine, cyanuric acid or the pH value. In order to carry out a measurement with the multi-parameter IoT sensor, a water sample of 10 ml must be placed in a cuvette. The built-in LED in the multi-parameter IoT sensor generates a test light in the wavelength ranges of 503 nm, 570 nm and 620 nm. A photodiode now recognizes the value to be measured based on the light transmission of the sample.

Each measurement is automatically saved by the multi-parameter IoT sensor. The stored measured values ​​can then be read out, for example, via a mobile device via the Bluetooth interface built into the multi-parameter IoT sensor. A free app is available to analyze the measured values ​​from the multi-parameter IoT sensor. It is also possible to establish a Bluetooth connection between the multi-parameter IoT sensor and a computer. Free software is also available for this, with which the measurement data can be analyzed. As another special feature of the multi-parameter IoT sensor, the measurement data can be uploaded to a cloud using both variants and accessed from anywhere. This service for the multi-parameter IoT sensor is also free of charge.
