Android-Based Mobile Application for Managing the Laboratory Air Conditioning Units

In this paper, a developed system using an android-based mobile application to replace the conventional remote controllers of air conditioning units. This android mobile device will be used as a controller to switch the power of the air conditioning (AC) units and an accurate time power consumption monitoring for each AC unit. The study uses Android Studio for the android programming development and a NodeMCU ESP8266-12E microcontroller board to establish the network connectivity between the circuitry and the android mobile phone. The system used the Arduino Uno board to read the voltage sensor (ZMPT101B) shield and current sensor (SCT-013-030)'s data. After conducting the sensors' testing and calibrations, results showed significant accuracy of 96.95%. The power ON command for the AC units from the android mobile phone has an accuracy rate of 99.91% and 99.85% from that of the power OFF command. Power consumption calculation, on the other hand, has 91.09% accuracy.
