We are still doing the research about the suction pump machine. A suction pump pumps fluids from patients to a bottle that needs to be emptied once it is full. The problem that we found was that when the bottle is full, the nurse sometimes forgets to empty the bottle so the fluid tends to flow into the machine and damage the motor. We are trying to design a circuit that will help to alert the nurses or guardians that the bottle is about to be full so that they can empty it.

We thought of designing an alarm system that will be attached to the machine. The system will have a water level sensor that will sense the level of fluid and then activate the buzzer which will then produce a sound.
