The present invention discloses a Lung condition monitoring device for performing ultrafast detection of humidity level in exhaled air while breathing out and therefrom detect condition of the human lungs in real time. The Lung 5 condition monitoring device comprises a mouthpiece for forcibly exhaling air there through, one or more humidity sensor to measure the variable electrical resistance based on level of adsorption of water molecules thereon of the humidity content of exhaled air and real time monitoring unit operatively connected to said humidity sensor and having correlating means for correlating 10 the change in humidity level and related variation in the electrical resistance due to exhalation to peak flow rate of the exhaled air for monitoring lung condition. The Lung condition monitoring device is also capable of wireless data transfer to any peripheral computing device such as mobile phone via wireless connectivity and show the test results on the mobile phone display with the help of a 15 proprietary application embodied in the phones operating system. The mobile interface increases the portability, data monitoring, and user friendliness of the device. Further, the mobile interface helps in storage and analysis of big time data for prognosis, diagnosis, and therapeutic purposes.
