For several people, bedroom is the most comfortable place in the house. Many people use the bedroom for activity and working too. But, how if the bedroom has uncomfortable condition, like there’s a strong smell from cigarette or the temperature and humidity are not ideal. The room conditions should be maintained for creating ideal and healthy air quality.

Based on that problem, I try to make Smart Air Purifier and Diffuser with Intenet of Things technology, so it can connect to the internet and get access from the smartphone. How this device works by filtering air using High Efficiency Particulate Air (HEPA) Filter and scent the room by aromatherapy steam. The device can be placed on the table and work 24 hours for keeping the room conditions. Beside that, there is alert mechanism by turn on the buzzer if somoone open the door when I’m sleeping, it prevent from theft.

I have been used many sensors for finished or on-going cyber physical projects. Sometimes the sensors work well as I expected and some sensors are not, easily configured or not, and cheap or expensive. It depends on the budgets for buying these sensor.

FYI, the sensor really has constrain. As we know the sensors manufacture like Senserion, DFRobots, Adafruits, etc build with their different specification.

In this article, I’ll give you the basic information about the sensors on several purpose of measurement.

I’ll keep updating the page.
