hello guys..

i'm kinda tired to do this project..
i will submit this project next week.. i hope to hear from the mmber that willing to help me..

my project title:
automatic shutdown for domestic gas stove..

kit use:
timer relay x 2
water sensor

concept:
1.detect the exist of the water (water boil and the water will active the sensor)
2.then, it will rotate the power window motor
3. to stop it at the correct time, i attach the timer relay.. after 10 second it will stop by itself..

the problem:
i cant use the copper plat as sensor..
to test it, i just need to tap the start wire and then separete it..
mean.. if there is water at that copper plat ..it cant work at all..

i will attach the real pic later... hope to get the reply from u after i attach the pic..

. . .if you're at sea level. In my home town water boils at 97° C.

add some salt to it and it will go up

Maybe I'll just wait one or two hundred years, then sea level will have risen instead.

you are wanting to shut the stove off when the water starts boiling, or when the pot boils dry?

 

[Hero999]

To detect when the water's boiling, you need to detect steam.

To sense when the pot boils dry, monitor the temperature of the bot and shut it down when the temperature exceeds 100°C.
