PCBA  Applications

• Personal Wellness and Mood Enhancement: The PCBA automates the diffusion of essential oils to create personalized environments, such as relaxing scents for stress relief in bedrooms or invigorating blends to improve focus in home offices.

• Spa and Hospitality Ambiance Creation: Used in hotels, spas, and salons to provide consistent, automated fragrance experiences for guests. The PCBA enables scheduled operation and remote control, ensuring a welcoming atmosphere without constant staff intervention.

• Yoga and Meditation Practice Aid: Enhances mindfulness sessions by dispersing grounding or calming scents like sandalwood or lavender on a timer, helping users create a dedicated sensory environment conducive to meditation.

• Air Quality and Humidity Improvement (Ultrasonic Models): In humidifying diffusers, the PCBA's ultrasonic transducer control adds moisture to dry air while dispersing scent, addressing comfort and air quality simultaneously in homes or offices during winter months.

• Healthcare and Therapeutic Support: Employed in complementary therapy settings to disperse scents believed to support wellness, such as using eucalyptus in a steamer-style diffuser to help clear sinus congestion during colds.

• Smart Home Integration and Scene Setting: Connects to smart home ecosystems (via Wi-Fi/Bluetooth). The PCBA allows users to integrate aromatherapy into routines—like starting a citrus blend when a "Good Morning" scene is activated on a smart home hub.

• Retail and Commercial Space Scent Marketing: Powers commercial-grade diffusers that consistently release branded or appealing fragrances in retail stores, showrooms, or real estate open houses to influence customer perception and behavior.

PCBA Features 

1. Ultrasonic Transducer or Heater/Pump Driver Circuitry: The core of the PCBA includes a driver circuit (oscillator and power stage) for the ultrasonic transducer that creates a fine mist, or a control circuit for a heating element/pump in nebulizing or evaporative models.

2. Multi-Mode Timing and Mist Intensity Controller: Features a microcontroller that manages user-selectable modes: intermittent (e.g., 30 seconds on/30 seconds off), continuous, and adjustable mist output levels to control scent intensity and water/oil consumption.

3. Water-Level and Dry-Run Protection Sensor Interface: Integrates sensors (optical or conductive) to detect low water levels. The PCBA's logic automatically shuts off the transducer or heater to prevent damage, ensuring safety and device longevity.

4. Ambient LED Lighting Controller: Includes an RGB LED driver circuit that allows for customizable colored lighting. Modes may include fixed colors, color cycling, or lights that sync with misting intervals, adding a visual relaxation element.

5. Multi-Mode Connectivity (Optional Smart Models): In advanced models, the PCBA incorporates Wi-Fi and/or Bluetooth modules. This enables smartphone app control for scheduling, creating scent blends, and integrating with voice assistants (Amazon Alexa, Google Assistant).

6. Advanced Power Management (PMIC): Utilizes a Power Management IC to efficiently regulate power from the AC adapter or battery source (for portable models). It safely distributes power to high-current components (transducer/heater) and low-power logic circuits.

7. Simple User Interface Control: Designed with interfaces for touch buttons, capacitive touch sensors, or a simple IR remote control receiver, providing users with an intuitive way to change settings without complex menus.
