VOICE CONTROL AIR HUMIDIFIER USING HC-06 FOR BARANGAY NOVA PROPER

Abstract

In recent years, the demand for smart household appliances has skyrocketed due to increasing health consciousness, the pursuit of convenience, and the availability of innovative technology at affordable prices. Among these appliances, the air humidifier stands out for its ability to improve indoor air conditions, particularly in environments affected by dryness or pollution. In Barangay Nova Proper, where residents regularly face shifting weather conditions and inconsistent air quality, introducing a smart and easy-to-operate humidifier can provide significant benefits in terms of health protection and daily comfort. The Voice-Controlled Air Humidifier using the HC-06 Bluetooth module was developed through a structured process involving hardware integration, programming, and communication testing. The project commenced with meticulous planning and system design, followed by the acquisition of key components, including an Arduino Uno microcontroller, an HC-06 Bluetooth module, a relay module, a humidifier unit, a power supply, and a smartphone with voice command capabilities.

The hardware setup involved connecting the HC-06 module to the Arduino Uno to enable wireless communication with the smartphone. A relay module was integrated to control the humidifier’s power supply based on received commands. All components were securely mounted on a board to ensure indoor safety and operational stability.

Programming was carried out using the Arduino IDE. The code was designed to read serial data from the Bluetooth module and execute the appropriate command to turn the humidifier on or off. A mobile application was used to capture voice input, convert it into text, and transmit the command via Bluetooth.

The Bluetooth connection was optimized for a stable and uninterrupted link between the smartphone and the HC-06 module. Proper baud rate settings and successful pairing ensured smooth data transmission. The voice command system was tailored to recognize simple instructions such as "turn on humidifier" and "turn off humidifier," enabling hands-free control. The Voice-Controlled Air Humidifier, developed using the HC-06 Bluetooth module, was successfully tested in Barangay Nova Proper. It enables users to turn the humidifier on or off through voice commands from a distance of up to 15 meters via Arduino-powered Bluetooth connectivity. The Voice-Controlled Air Humidifier using the HC-06 Bluetooth module was designed for residents of Barangay Nova Proper, specifically to assist individuals with limited mobility by allowing hands-free operation.
