Hello dear friends!

 

I'd like the cookers to reduce and adjust their power automatically when the liquid in the pan starts to boil, or the oil in the frying pan. Induction cookers, and some others, react quickly enough for it.

 

Maybe they exist already? I suggested it to a Spanish company in 1996.

 

I imagine the sensor could listen to the noise injected by the pan or frying pan in the cooker. Something like a wire could transmit the mechanical noise from the hot area to the vibration sensor working at cool temperature.

 

Then, electronics could first filter the high frequencies or sharp transitions associated with bubbles, then either count the bubbles per time unit or evaluate the strength of the bubble noise, to inform the regulator circuit.

I thought most induction cookers are already temperature controlled.

But that won't let water boil gently, will it?

As a sensor for boiling water or oil, I thought naturally of piezo sensors for acceleration or force, but a pickup microphone as on an electric guitar is an interesting option.
