Development of Robotic Aromatherapy Air Humidifier Using Arduino

Abstract

Nowadays, people have become more concerned about maintaining their health. Hence, an air humidifier is one way to keep the air moisturized, cleaner and safer to breathe in. Even though people are gaining knowledge on how to clean the air, these methods are still insufficient to ensure good air quality. If the air humidifier keeps moisturizing the air, it can make the humidity level too high, and this also can cause harmful side effects. The idea of this product is to create an air humidifier that can detect the temperature and humidity of the surroundings and automatically produce the water mist if the moisture of the surrounding is too low (RH < 55%) and stop the water mist if the humidity of surrounding is too high (RH > 55%). The heating plate will warm the water to produce a warm water mist if the temperature is low (Temperature < 24˚C) and stop the heating when the temperature is high (Temperature > 24˚C). This product is also designed to be moveable by itself to cover a large area in the room. The unstable temperature indoors due to air conditioning and the weather outside the house can cause problems to health. The sudden temperature change can cause the body to have a fever or skin discomfort. To maintain the suitable room temperature, this product provides a system that uses a heating coil and produces a warm mist to comfort the skin. In the existing product, the humidifier is static and usually placed in the room's corner. Since the water mist is produced based on the humidity surrounding of the product, it can only react depending on the humidity in the close area. The problem occurs when the humidity at the corner with the humidifier is different compared to the other corner of the room without the humidifier. The unbalance of humidity will happen, and the resident will benefit less. Hence, this project is designed to be robotic, which it is installed with a self-driving motor that act by itself to move around to detect the humidity around the room and cover the humidity in a large area. Therefore, this project is beneficial for patients suffering from skin conditions such as eczema and respiratory problems such as asthma who are required to be in clear air and the proper air humidity.
