<![CDATA[The fire was a disaster often happens in the environment community , to minimize loss because of fire incident detection system so he made a fire that uses a fire as detector tools .But some sensors that is on a detection can damage , which can be caused by several factors .May be needed to a system that could meredudansi primary system when damage occurs .To research it uses 2 sensors that is the censor ky-026 as a fire , and censorship dht 11 as a temperature and humidity on each module master and module slave and uses the hot sparing standby. This method is the way finishing activate module of a slave in a continuous manner although considered to sleep and is always ready replace module master when master module damaged sistem.dilihat module from the results of the testing master and slave module will walk and flawlessly , and also slave capable of meredudansi module module master when subjected to damage to censorship and experienced power module dead .The system also to distribute the results of sensing to the application of a telegram and found displayed on the application a telegram.]]>
