Water information displaying device for e.g. swimming pool, has electronic analysis card for collecting electrical signals of probes and sensors and converting signals into digital data, and antenna for sending data to radio emitter

摘要

The device has an immersed case (1) comprising a hydrogen potential probe (4), an oxidation-reduction probe (5), a conductivity probe (6), a water temperature probe (7), a water level sensor (8) and a water presence sensor (10). An electronic analysis card (11) collects electrical signals of the probes and the sensors, and converts the electrical signals into digital data. An antenna (9) sends the data to a radio emitter (12) in the case. A non-rechargeable battery (14) supplies energy to the case. An over-molded magnet is fixed on a wall of the basin.
