How to make fire alarm circuit  

Is it neccesary to connect switch with the circuit? And how have u connected the terminals of the battery?

Thank you

Fabulous bro

Thank you 😊

Brother tell me.. Ir reviver light size is 3mm or 5mm.. Which one you used??

Nice bro👍👍👍

You save my life, thanks i hope it works

Bro it (ir sensor ) will detect everything not just fire each every thing ,until and unless it is not of black color . So it is not a fire alarm it is a object sensor

Verry verry thanks bro

Bro resistor not required ?
