Abstract: A device for measuring physical and/or chemical parameters of water circulating in a treatment circuit of a leisure pool comprises: a main body (12) through which a measurement channel (13) passes; a connector (14a, 14b) for connecting the measurement channel (13) to the treatment circuit (8); at least two measurement sensors (18a, 18b) fitted to the main body in order to be in contact with the inside of the measurement channel (13); and an acquisition unit (20) connected to the measurement sensors and comprising a self-contained electric power source (32) and wireless communication means (45) for communicating with a central unit (5).

Abstract: Method for managing a group of swimming pools, characterized in that it includes the following steps: measurement or estimation of at least one datum representing the water quality of each swimming pool (11; 13; 15; 17) in the group by its own local monitoring means (21; 23; 25; 27), transmission by the local monitoring means (21; 23; 25; 27) of this at least one datum to a remote server of a management centre (30; 40, 40?) via a communication network (20).

Abstract: Method for managing a set of swimming pools, each swimming pool being provided with a means of monitoring the quality of the water contained in the swimming pool, each of the monitoring means communicating by means of a communication network with at least one management centre, characterized in that it comprises a first step of detection of a degraded state on at least one swimming pool of the set, called “victim swimming pool”, and a second step of determining swimming pools of the set threatened with turning into a degraded state, each called “threatened swimming pool”. Management centre for a set of swimming pools implementing such a method, device for managing a subset of a set of swimming pools, means of monitoring the quality of the water contained in a swimming pool and use of a swimming pool as sensor to determine a potential risk.
