Create a schematic and PCB design (include layout, BRD, and BOM library files) for a multi-chamber ultrasonic piezoelectric atomizer controlled by an particle photon microcontroller.
The system is comprised of 5 separate chambers, filled with a fluid, at the bottom of the chamber is a ultrasonic vibrating mesh atomizing disc that is actuated by a ring piezoelectric.
There is one atomizing disc per chamber.
At the end of the chambers there is a fan that pushes the atomized fluid into the air.
The fan is to be controlled by PWM on the photon microcontroller.
Each piezoelectric disc is to be controlled by the photon particle microcontroller. https://www.particle.io/products/hardware/photon-wifi-dev-kit
Please either use the p1 or photon breadboard in your designs.
For control, each individual piezoelectric disc should be able to turn on and off within 1 second.
LED indicators for status of the atomizer shall be implemented, along with micro-usb connectors, power, and reset switches.
Piezoelectric Driver KS-W16-142K is currently being used. Please see attached datasheet for details.
Photograph of current piezoelectric driver which only supports one piezoelectric drive is attached.
