The as-synthesized nanosheets are characterized using X-ray diffraction, Raman spectroscopy and Transmission Electron Microscopy (TEM). The humidity sensing behavior of SnS2 nanoflake sensor device were investigated in the range of 11-97% of relative humidity (RH) at room temperature. The response time of similar to 85 s and recovery time of similar to 6 s were observed for the SnS2 nanoflake based humidity sensor. A maximum sensitivity of 11.300% is recorded. We also investigate the SnS2 nanoflake based alcohol sensing properties towards methanol, ethanol and iso-propyl alcohol. An exclusive selectivity towards methanol with a response of 1580 is shown as compared to other analytes. The response time of similar to 67 s and recovery time of just 5 s were observed for the SnS2 nanoflake based methanol sensor.1 aBharatula, Lakshmi, Deepika1 aErande, Manisha, B.1 aMulla, Imtiaz, S.1 aRout, Chandra, Sekhar1 aLate, Dattatray, J.  uhttps://library.ncl.res.in/content/sns2-nanoflakes-efficient-humidity-and-alcohol-sensing-room-temperature
