A Smart Whistle Counter For Cooking And More

ashwiniThis article describes a smart electronic counter that counts the number of pressure-cooker whistles and also time duration of the cooking. It triggers a buzzer alarm when the preset whistles count or preset cooking time duration is reached.

This design can also be used in factories having boilers with pressure release valves to automatically turn them off on hearing the sound at boiling point. Or it can be used in steam engines to automatically cut off power when sound is made by the vessel’s outlet valve.
