Internet of Things (IoT) is the dynamic multidimensional web of technological heterogeneous artifacts. It is changing smart style of human life into ultra tech vibrant multi style of life. The usage of technology in the layman’s life and profession is the ultimate objective of modern scientific inventions. The drainage block is one of the tedious problems faced by all the developing countries. The drainage block yields many sanitation problems, highly infected diseases and flood monsoon seasons. The maintenance of drainage systems is highly expensive; the humans are involving the cleaning and maintenance activities. This is killing thousands of humans every year. This research article is proposing a new technique and giving the solution for finding the blockage of drainage using air, temperature and pressure constants. The sensors are used to identify the values for each parameter. The Automatic Drainage Block Identification Algorithm (ADBIA) is analyzing the values and predicting whether the drainage is blocked or not.
