In this project, An Advanced Underground Drainage Monitoring And Automatic Rescue System using Internet of Things is proposed to protect the sanitation workers form health issues. In India sewage can be cleaned from manholes and drains are a difficult and risky task for anyone, but these people/workers are forced to do these jobs just to earn for their family economy. In order to overcome this issues, a new device is proposed to monitor the human health while entering into the sewage and provide the health parameters in the real time to the officials outside or the control room. Particularly, blood pressure of sanitation workers and toxic gas level of drainage is monitored using this new proposed rescue system. The main component of this system is Arduino controller. There are three types of sensors such as Toxic gas sensor, Methane gas sensor and Ultrasonic sensor used for the proposed system. Water level indicator is used when drainage is full to find from ultrasonic sensor, SMS will be send through GSM technology. Methane Gas and Toxic gas sensor level is high, Buzzer will be ON at the same time location will be share automatically with the help of GPS. The received sensor details display on LCD at receiver with help of GSM. The performance of proposed system is compared with other existing system and shown to be more effective in terms of protect the sanitation workers from health issues.
