Heelo sir

Sone body adviced me a circuit diagram to operate IR sensor form a 6volt or more

Here a resistor is used having a lil.bit higher value but i don't know that



Is the idea worth or a crap ? or say enough to damage the IR device ????

If it is usefull then what would be the value of resistor ? please tell
 





ok i got it 6 volt is given but why you are advicing to drive it with 5 volts ?
too other ckt designs have same strategy observed . . . . . . . . . . . .

Why to force part to work on edge of specification? Design should be optimal.

As additional to this 6V battery, I supose its lead acid tech, at full level have 6,36V!

Parts should work in specification range. I dont say that part cant work on 6V, but its risky.

For my thinking for longer and optimal life of parts and best working capabilities, better supply parts with stable and optimal regulated voltage, for reference use manufacturer datasheet.

:wink:


How NASA application goes? :smile:
 





okk ya sir you are right these small things have to keep in mind

yo sir i joined that forum & futher links you gave is with me , procedures ll be on its way next day

My criteria keep me working on a single job till it completes sooooooooo . .. . . .
