Baby Cry Alarm

Here’s a beneficial model for today’s parents. Suppose a baby is sleeping in his swing cradle and he or she urinates which makes him wet, but the mother may not come to know this as she is not close by to the child. So for this type of situation a swing the cradle is made which will alert you whenever the baby urinates. As it is like an open circuit when baby wets the cradle the circuit gets completed and the chemical energy is converted into sound energy and the buzzer goes on.
