Project BREATHING
A Low-Cost semi Automatic Breathing machine with Automatic Air Purification System
TEAM π
An air purifier is a device that filters the dust and some of the heavy particles in air. And a ventilator is a device that is used to pump air to the lungs of patients who are unable to do it by themselves. This project is a fusion of both the products with reduced cost and for a type of patient who needs a ventilator but the surrounding is dusty and smokey.
Two parts are built individually, can be used as a room air purifier as well as a breathing system for critical medical care. This system is made semi-automated so that it can sense type of air surrounding it and choose the filtration process by itself.
Objective
Mainly this project is focused on combining two different mechanisms to produce a single detachable product that can either be used as a room purifier or a semi-automated ventilator termed as breather. The objectives of the project are-
-
Lessen the manual operation.
-
To save time,
-
Automatically adjust purifying settings,
-
Be budget friendly.

Abstract
In much of the world, people spend on average 65% of their time indoors at home. Therefore, it is important to understand the air quality in homes and how best to improve it. To create a safe indoor environment, Automated Air Purifier with smart control and sensor technology can be used, which promises to reduce indoor air pollutants effectively. The product will be useful for those who has allergic and respiratory diseases and for the places where the air is not so fresh.
​
The Automated Air Purifier operated under two automated operation settings:
i) The two suction fans in the front circulated automatically;
ii) a sensor-based mode in which a smoke sensor is used to determine the presence of smoke if the smoke is detected, the dedicated suction fan circulated and move the smoky air in another filtration stage.
Then the purified air is pumped out from the automated air purifier and gets into the storage bag. Then an automated ventilation system is employed to help patients who experiences trouble to breathe naturally. Best use of it is for a moderate-level critical patient. The storage bag is subjected to periodic squeeze with a mechanical mechanism 'circular motion to reciprocating motion'. The entire system will be driven by a microcontroller-Arduino UNO. Different types of filters for the filtration processes are planned to use which would be cost-effective and be user-friendly too. This project directs to an automated sensor-based approach to optimize the use of automated air purifiers for effectively reducing indoor air pollutants as well as reduce the manual labor. It would be a two way product, can either be used as a room purifier as well as medical purposes.
Methodology
The entire process can be subdivided into two steps.
​
The purifier part; Normal room air is sucked into the inlet chamber by the means of intake fans. If there is any presence of smoke, general fans would be turned off and the other fan would start running to let the air pass through the smoke filter. After that the general filter traps the polluted particles and while passing to the vacuum chamber. Vacuum chamber works like an one way valve, pure air is pumped from this chamber to the outlet chamber; so that no air flow can occur in reverse direction. Finally, purified air is forced to go through the outlet chamber by the outlet fan.
The Breather part; Purified air from the outlet is sent to a storage bag, which is under periodic pressing by a servo motor. Motor inputs are calibrated depending on the conditions of the patient.
