The project gives the solution for the problem in the manual scavenging processes. Manual scavenging refers to the practice of manually cleaning, carrying, disposing or handling in any manner, human excreta from dry latrines and sewers. The manual scavengers are exposed to harmful gases such as methane and hydrogen sulfide, which causes infections like hepatitis, leptospirosis, skin problems and respiratory system problems. The scavengers were affected by acute lung disease while inhaling methane gas in the scavenging environment. The proposed system monitors toxic gas (methane) in the scavenging environment and heart beat pulses of the workers, using multiple sensors. Light fidelity (Li-Fi) technology is introduced to forecast the monitored data. Li-Fi uses LED light source to transmit the data in a wireless manner this method is widely called as VLC (visible light communication). The detected values are sent to the receiver part through VLC transmitter and receiver. These values are displayed in the LCD in the receiver section to ensure the workers conditions. Thus by using this Li-Fi technology data transmission and reception can be done in problem less manner.
