The Arduino Abstract - Proper humidity ensures comfort and creates a healthy indoor environment. Traditional humidifiers lack the efficiency and intelligence to change dynamically with fluctuating environmental conditions. This paper presents an affordable smart humidifier system that makes use of advanced technology in managing room humidity. The controlling unit is an Arduino microcontroller that continuously monitors parameters like humidity, temperature, and air quality. It monitors in real time the moisture provided by a humidity sensor and the data is processed by Arduino. When the humidity goes below the threshold value, it triggers a relay module that, in turn, activates the spray module, injecting moisture into the air from an external water container. The proposed work aims to develop an affordable smart humidifier for indoor applications.

The Arduino-based microcontrollers along with suitable sensors have been used for monitoring environmental parameters, specifically humidity and temperature. Arduino is highly effective in integrating with sensors to provide accurate and real-time data. The work supports the use of Arduino in developing responsive and efficient systems for observing environmental changes [3]. The integration of Arduino microcontrollers within IoT-based smart home applications, highlighting Arduino's capability to connect with various IoT devices for remote monitoring and control via the internet is explored. The work underscores the Arduino's potential in creating interconnected smart systems that can be easily monitored and adjusted through the IoT platforms [4].
The Arduino plays a significant role in prototyping across various domains, emphasizing its widespread use driven by cost-effectiveness, ease of programming, and strong community support. Despite challenges like limited processing power and memory, which may pose constraints for complex projects, the review highlights Arduino's suitability for applications such as a smart humidifier. Its advantages, including rapid prototyping and the flexibility to integrate sensors, make it a practical choice for developing efficient and responsive control systems [2].

1. INTRODUCTION A smart humidifier is an intelligent device that is responsible for regulating and maintaining the highest possible humidity in a room or space to provide comfort and healthy living conditions. Humidity is among the most pertinent factors in indoor air quality that relates directly to health and comfortable living. Indoor heating can drastically reduce the humidity levels in dry climates or during winter months, leading to dry skin, respiratory issues, and overall discomfort. A smart humidifier resolves these issues with its automatic adjustment of humidity within a desirable range and is thus considered to be a very important tool in improving indoor air quality. The backbone of the smart humidifier is an Arduino microcontroller. The Arduino is programmed to command the different sensors and components that make up the smart humidifier.
In sensitive applications, a compact weather station is desired, which is cost effective and small size, so as to provide critical information about temperature and humidity. The study highlights the crucial role of precise sensor integration in achieving optimal humidity control system [5]. The control of electrical equipment using relay modules using Arduino is considered. Arduino can efficiently manage devices by using relays to switch circuits on and off [6].
