A smart home ambiance maintenance system that integrates sensors to read odour levels, automatically sprays room freshener (rose or jasmine) when odour reaches a low level, and can be controlled by human voice commands. The system ensures a pleasant home environment through continuous monitoring and automated response to air quality.

The invention provides a smart home ambiance maintenance system comprising an odour sensor, a spray mechanism, a microcontroller, and a voice control system. The odour sensor continuously monitors air quality. When the odour level falls below a predefined threshold, the microcontroller activates the spray mechanism to dispense a rose or jasmine freshener. The system also allows users to control the spray mechanism through voice commands.
This invention relates to a system for automatically maintaining a pleasant home ambiance by monitoring and controlling odor levels. The system comprises an odor sensor, spray mechanism, microcontroller, voice control system, and mobile/web application.
The odor sensor continuously measures the air quality and detects odor levels in the room. Based on the sensor readings, the microcontroller makes decisions to trigger the spray mechanism. If the odor level is low, a rose-scented freshener is sprayed. For moderate odor levels, a jasmine-scented freshener is used. If the odor level is already good, no action is taken, and a message indicating a good odor level is printed.
The system also includes a voice control system that allows users to issue voice commands to control the spray mechanism. For example, users can say "Spray rose freshener" or "Turn off the spray" to manually control the system.
Additionally, a mobile/web application provides a user interface to monitor sensor readings and manually control the system. Users can view the current odor level, temperature, and humidity, as well as trigger the spray mechanism remotely.
The system operates by continuously collecting data from the odor sensor. The microcontroller processes the sensor data and compares it with predefined thresholds. If the odor level falls below a threshold, the microcontroller activates the spray mechanism to dispense the appropriate freshener.
Users can interact with the system through the voice control system or the mobile/web application. The voice control system interprets voice commands and sends signals to the microcontroller to control the spray mechanism. The mobile/web application provides a visual interface for monitoring sensor data and manually triggering the spray.
The system's data flow and workflow involve data collection from the odor sensor, data processing by the microcontroller, decision-making based on predefined logic, and user interaction through voice commands or the mobile/web application.
The odor sensor integrates with the system to record real-time parameters of airborne contaminants and odor intensity. The sensor is continuously active and collects data at specific intervals.The microcontroller or edge device receives sensor data, preprocesses it for optimal accuracy, and detects whether odor levels require freshener dispensation based on predefined thresholds.
The automation logic within the system determines when to trigger the spray mechanism based on the odor levels. It integrates with actuators to send signals to the spray mechanism for automated freshener dispensation.
The voice control system receives and interprets voice commands from users for manual operation of the system, such as triggering the spray or turning it off. It integrates with the microcontroller to execute these commands.
The mobile/web application provides a user interface for monitoring and controlling the system. It allows users to view real-time sensor data and manually trigger freshener dispensation.
Implementing the system involves selecting appropriate hardware components, such as sensors and microcontrollers. The necessary algorithms for real-time data processing and decision-making need to be developed. Proper integration of sensors, microcontrollers, actuators, voice control, and user interfaces is crucial. Thorough testing and validation are required to ensure system performance, sensor accuracy, and the reliability of system actions.
For maintaining home ambiance by monitoring odor levels, the system continuously checks the odor level in the room.
• If the odor level is low (below 30), a rose-scented freshener is sprayed.
• If the odor level is moderate (below 60 but above 30), a jasmine-scented freshener is sprayed.
• If the odor level is good (above 60), no freshener is sprayed, and a message indicating a good odor level is printed.
• If the sensor data cannot be read, a message indicating a failure to fetch sensor data is printed.
• There is a delay of 10 seconds between each reading and freshener spray to avoid constant operation.

The provided code implements a Smart Home Ambiance Maintenance System that operates by fetching sensor data from a cloud-based API to monitor and adjust ambient conditions, particularly focusing on the odor level. This system simulates the process of obtaining real-time environmental metrics and making decisions based on these metrics to ensure a pleasant home environment.
Here are key points that can contribute to the novelty of your Smart Home Ambiance Maintenance System (SHAMS):
1. Integration of Sensors: The system that is proposed here is SHAMS which employs the odour sensor that can be used to measure air quality as well as detect odour quality in real time. This particular sensor is important to help predict when room freshener should be released in the room since it catalyzes change in the quality of air in the environment.
2. Automated Response Mechanism: The proposed system encompasses microcontroller that naturally activates the spray mechanism when the odour level falls below the threshold established by the user. This automation enhances the comfort of the user and at the same time, the consistent maintenance of the comfort of the home.
3. Voice Control Interface: A voice control system is incorporated that permit commands to be provided to the system through the voice. This feature comes in handy and convenient to use and women and men can regulate when and how the room freshener is dispensed without physically touching any device or interface.
4. Comprehensive User Interface: A mobile/web application supplements the system because it provides a friendly front-end to permit the user to view data acquired from the sensors and make her/himself a rough control system. This aspect improves user satisfaction by enabling the client to acquire current data regarding the quality of the air and to manage the settings of the system for themselves.
5. Customizable Freshener Options: SHAMS provides the availability of dispensing multiple forms of the room fresheners; rose or jasmine, per the user’s preference on scent. This feature distinguishes the proposed system apart from other systems that may have limited or fixed methods of dispensation of perfume.
