Monitoring Bracelet

The key to the system is a monitoring bracelet worn in active
mode by everyone using the pool. The computer measures both the depth and the time under water by constantly measuring the distance between the swimmer and the water’s surface. The distance can be set to between 5 and 125 cm and as soon as a swimmer goes below the programmed depth, a stopwatch begins to count the seconds. This can be set to anywhere between 5 and 95 seconds.As soon as the presetinterval expires, the monitoring bracelet sends an ultrasonic signal that is detected by a receiving sensor installed in thewater. This in turn is connected to an alarm unit that triggers both an acoustic and visual alarm.
