We have developed a novel combination of indigenous mosses which rejuvenates air in closed spaces by removing particulate matter and reducing carbon dioxide and nitrogen oxides.

 

The Purpose

Modern buildings are designed to maximize energy efficiency and have reduced fresh air exchange. In addition, bad quality of city air and use of synthetic building /furnishing materials that evolve volatile organic compounds, causes a variety of health problems such as skin rashes, lethargy, respiratory congestion, asthma, allergies, etc. We have developed a novel combination of indigenous mosses (belonging to genus Sphagnum, Taxiphyllum and Vesicularia), which rejuvenates air in closed spaces by removing particulate matter and reducing carbon dioxide and nitrogen oxides. Mosses used are native to our country and would not be an invasive species.

The Technology

Our moss-based device includes an in-built soil moisture sensor and connected water pump to keep moss hydrated and growing without manual input. It can cover spaces on walls and ceiling and be an aesthetic addition to any home.

Additional Details

In addition to our moss purifier we have also developed smart home devices which is as follows:- i)PIR motion sensor ? PIR motion sensor is coupled to a 555 timer to enable time-bound functionalities such as automatically preparing coffee upon sensing motion in mornings or evenings as per pre-set directions. ii) WiFi module ? This enables connectivity between all moss-devices and creates an Internet of Things (IoT) platform. iii)Wearable accelerometer and gyroscope- We can utilize data from triaxial accelerometer and gyroscope to detect user muscle contractions and ?learn? state of user (active, lethargic and sleeping) then control the type of music.
