PENERAPAN WIRELESS COMUNICATION HC-05 PADA MODEL KENDALI ECOSYSTEM (EVAPORATIVE COOLER SYSTEM)

The interconnectedness of the times includes all aspects, one which is temperature earth getting warmer, annual prediction increasing by 1 ° to 1.5 Celsius. In addition, there are technological updates with ideas that a daily necessity. Evaporative Cooler conventional air conditioner throughout world various types and types, DEC (Direct evaporative Cooler), for example works converting sensible heat into latent heat, whose main circuit consists an electric motor, swing cooler motor 24V DC water pump, actuator module used in implementation this system. idea came up was not many people paid attention system its use. This research will apply wireless communication, namely Bluetooth HC-05 Module control model design using ECOSYSTEM (Evaporative System) where input integrated artificial application installed on smartphone devices it android operating so can communicate between systems. Focusing communication performance applied 2.4GHz frequency as receiver or sender commands range signal distances be given, equipped Arduino UNO ATMega328 microcontroller core controllers. Over-the-air does require other media process working. Measurement coverage proven horizontally vertically, intended because difference capture power transceiver signals well conditions when bluetooth controlled, connected yet connected. test, only captures two working, still affordable, connect remain delay more than 0.02 seconds at farther.
