Week 16. Applications and Implications¶
What it will do ?¶
For Final project I am making a small air humidifier device that can be placed on a table in any interior. It is improving air quality in the area and also it’s serving as a lamp when LEDs are on.
Who has done what beforehand?¶
-
Humidifier with using piezoelectric atomizer - Aditya Agrawal

Processes¶
Questions to be answered¶
-
how water level can be low above the fog maker but full in the tank. How water can be delivered to the fog maker.
-
different voltage consuming outputs on one board.
-
electronics isolation from water.
How will it be evaluated?¶
-
Test board with all the outputs and inputs work in one system and able to be controlled by the microcontroller.
-
Different voltage consumption parts achieved with voltage regulation system.
-
All parts assembly with solved water isolation problem.
-
Programming the microcontroller to have an ability switch on and off the outputs and the inputs systematicly and in the right order.
