Abstract: Disclosed is a device for analysing water and a swimming pool equipped with such a device. The device includes: an analysis chamber provided with at least one water inlet and at least one water outlet; a sealed housing adjacent to the analysis chamber and isolated from the analysis chamber by a partition; a data processor housed in the sealed housing; at least one probe electrically connected to a data input of the data processor; an electrical power supply electrically connected to a power input of the data processor, the electrical power supply having an electrical generator provided with a turbine housed in the analysis chamber, the electrical generator being electrically connected to the data input of the data processor. The device is useful for monitoring the sanitary state of the water of a swimming pool.

Abstract: The invention relates to a lighting device and method, in particular underwater, including: a plurality of spotlights comprising at least one light source nude up of a set of LEDs, the spotlights being connected to an electric power source; and at least one control housing connected to said power source and communicating with each one of the spotlights, said control housing being provided with a cut-off device configured to transmit control instructions via a power cut-off member to the spotlights, which are provided with an on-board detector having a microprocessor configured such as to interpret said control instructions and to adjust a signal capable of modifying the color of each one of the LEDs that make up the set of LEDs, characterised in that the control instructions transmitted by the cut-off device are transmitted in the form of a code made up of combinations of power cut-offs with various durations.

Abstract: A device for colorimetric measuring and signaling of one or several physicochemical values of a liquid medium is disclosed. This device includes: at least one sensor capable of measuring at least one physicochemical parameter of the medium; at least one light indicator designed for emitting a colored light with variable color depending on an electrical control signal; and an electronic control circuit connected to a sensor and configured to convert at least one measurement of the sensor into an electrical input signal of the indicator to cause the emission of a light with a color depending on the measurement of the physicochemical parameter.
