Abstract: Climate change is one of the major challenges in front of mankind. Air pollution is the primary reason for climate change and hence, monitoring air quality followed by air pollution abatement is essential to preserve the environment. Air quality monitoring can be done efficiently by developing compact, low power, and low cost sensors for sensing the air pollutants. We have developed MoS2 based sensors to detect NO2 at room temperature. A compact and low cost electronic circuit was designed and assembled to replace the table top read out circuit and make the device portable. The assembled circuit board can also facilitate interfacing the existing sensors that are available in the market such as temperature, humidity, CO. This work provides a proof-of-concept of developing a portable resistive sensor for detecting some of the air pollutants.
