Temperature and #elative humidity

Temperature is a measurement o' the avera&e kineti% ener&y o'the mole%ules in an ob*e%t or system.

Relative humidity is the ratio o' the a%tual water vapor pressureto the equilibrium vapor pressure over a plane o' water.To prevent the e''e%t o' temperature and humidity %onsider the'ollowin&

The Microcontroller A mi%ro%ontroller is a %ompa%t mi%ro%omputer that

%ontains many %omponents desi&ned to &overn theoperation o' embedded systems. A typi%al mi%ro%ontrollerin%ludes a pro%essor, memory, and peripherals.

P ! "icrocontroller () mi%ro%ontrollers are ele%troni% %ir%uits that %an be

pro&rammed to %arry out a vast ran&e o' tasks. () mi%ro%ontrollers allow ele%troni%s desi&ners to add

intelli&en%e and 'un%tions that mimi%s bi& %omputers 'oralmost any ele%troni%s produ%t or pro*e%t.

(ensors and Transducers A transdu%er is a devi%e that %onverts one 'orm o'

ener&y to another. A transdu%er %an be a sensor oran a%tuator.

A sensor devi%e whi%h dete%ts or measures a physi%al property and re%ords, indi%ates, orotherwise responds to it.

An a%tuator is a type o' motor that is responsible'or movin& or %ontrollin& a me%hanism or system.

Recommendations and Future 0or1s

The system in this pro*e%t was desi&ned to 'un%tion in theMediterranean re&ion there'ore i' it would be applied inother re&ions one must alter the system to ad*ust to that

re&ion. i' a %omplete system would be desi&ned one %an use a

phototransistor as a relay to %onne%t the %ontrol %ir%uit tohi&h volta&e devi%es.

@hen desi&nin& a %ustom made system 'or a spe%i'ied'un%tion or pla%e you must take noti%e the pre%autions instorin& papers and apply the %old stora&e i' possible.
