Abstract

The Flights will be confortable and not a problem for air transport service users who journey frequently by airplane within a short distance of 2-4 hours. It will be, for users air transport service who have never used an aircraft, mainly flight with long distances can cause some difficulties and feelings of discomfort because air temperature and humidity can be have to changer of the normal condition. Meanwhile, at a flying altitude of 30,000 feet, the air temperature condition in the aircraf cabin the average is 20ºC and humidity is 60%. but under certain circumstances air temperatur and humidity in the aircraft cabin can be have to changer, even exceeds the normal comfort limit of human. Under these conditions, without the normal temperature and humidity in the aircraft cabin, humans will experience uncomfortable such as heat, cold, skin diseases and hypoxia. To ensure the availability of information and warning system of temperature and humidity conditions in the aircraft cabin, it is necessary to design a system of temperature and humidity measurements within the aircraft cabin by the method if the temperature and humidity of the air in the aircraft cabin reaches more than the normal human comfort limit ie (temperature> 32 ° C and Humidity> 73%) then the system will alert (warning) via buzzer and visual warning on android Warning from the test results of the system in the visual display of the form (Cabin not Safe) and the sound indicator is Buzzer, DHT-11 Sensor used in the system to measure the value of temperature and humidity can work in the range (temperature 3-42°C and humidity 23-90%). on testing the comparison of temperature and humidity with hygrometer obtained difference of measurement average with difference of temperature measurement value between DHT11 sensor with Hygrometer that is 2°C, while difference of mean value of humidity value is 5.44%. The working distance of Bluetooth HC-05 in accordance with the analysis that has been done is between 1 to 10 meters. Bluetooth can not be reached when the distance of the tool with android phone more than 10 meters.
