HI Guys, i have a problem on this circuit.. it is a fire alarm circuit with a heat sensor lm35... i want to connect a relay in to it, so that if a heat is detected the relay will be trigger is it possible.... please i really need your big help.. tnx
can anybody help me about this problem.... i have a fire alarm circuit for detecting heat or change in temperature... but is it possible that it can have other application aside from fire detection.. as we all know LM35 can detect heat at the immediate vicinity..
so im looking for other...
hi guys any one who can help bout this! same with the one that i posted before its a circuit protection able to detect high voltage and low voltage and tripping it....
i have a problem when i testing it.. the wire from the transformer connected to the wall socket blow up.. what do you think the problem? hope you can help me.. thanks in advance..
what am i going to do with the ground? what i did in my experiment is i delete the ground of the part with the red box... and the ground of the other came from the regulated 5volts? but what happen is that all the LED is activated... and the same voltage drop is measure at the transistor even i...
i have a problem in testing the circuit... We d0nt have an hv2405 ofline regulator? Instead of the circuit provided in the diagram.. We change it to a transformer with 7805 regulator but the fuse exploded... Is the ground of the circuit different with the neutral of the main?
