Abstract

SENSORs GAS sensors are at the core of IoT-based environmental monitoring that we survey in the paper. There are also gas sensors and approaches to detecting different gases quantum efficiently. IOT based technology will for long these sensors will be hooked up with a lot of devices for sending real time data between devices, monitoring them, and taking in own decision for automation purpose. These advantages come in the form of greater accuracy, more spatial and temporal implications, and enhanced data analysis (much of which is driven by artificial intelligence and machine learning). The paper presents recent progresses of gas sensor technologies and also provides new challenges/ opportunities from the gas sensor systems and technologies if sensors are embedded into the IoT nodes and applied to smart city, health and agriculture. But now that IoT ecosystem gas sensors are in play, environmental monitoring is about to get more efficient, reliable, and smarter. Thirdly, based on their internet connecting characteristics, the task completion and (de)transmission of data by the IoT end devices can be unmanned and the whole process can be completed automatically, so, there are lots of regularities can be used for the harmful gas detection and the environmental monitoring to improve their work.
