Hazardous Environment Monitoring using Raspberry Pi Based Network
Project Area of Specialization Internet of ThingsProject SummaryIn underground mines communication is a major problem as the wired system gets affected due to seismic and other mining activities leading to low productivity and high cost. Another constraint is that the dynamic nature of mines, make the underground environment uninhabitable for the miners. Monitoring and navigation of mines have always proved to be a difficult task as there’s no way to monitor what lies ahead and in depths of mines. The conceptual framework of this project focuses on a wireless system for the monitoring of these areas and to avoid accidents. The proposed system includes Raspberry pi, microcontrollers, transceivers, sensors to transmit an image and sensor data to the user end to analyze and monitor the hazardous change inside the mines. With the help of effective communication from one pi to another using low power wireless nodes and readings of environmental parameters through sensors it is ensured that the area is safer for the miners to carry out their activities.
Project Objectives- To develop a real-time application to provide communication in underground environments.
- To implement continuous monitoring of environmental parameters, i.e. poisonous gas, high temperature, pressure, and humidity.
- To provide multi-hop infrastructure between nodes for transmitting sensor data.
- To implement low power and low-cost wireless system to measure the effectiveness and reliability of the system.
This system will comprise of two Raspberry Pi microcomputers in which one will act as a transmitter and the other will act as a receiver. The transmitter Raspberry Pi will be equipped with a Pi camera, an NRF24l01 transceiver module and several environmental sensors (temperature and humidity sensor, gas sensor etc.) . The transmitting Pi will take images from Pi cam as well as sensor data from the sensors and transmit it using the nrf module. The nrf module is used due to its low power consumption and high data rate. Several intermediate nodes will be placed between the transmitter and the receiver for the communication of data between them without the use of any internet connection. The nodes will be comprised of a microcontroller and an nrf24l01 module which will read the data from the transmitter, and then pass that data to the other node comprising of the same hardware as the previous node. The nodes will pass the data from the transmitter to the receiver. In case of node failure, a redundant node will be available so that the data reaches to the receiver without any disruption.
Benefits of the ProjectThis project will benefit the workers in underground hazardous environments. The environment can be monitored both visually and using sensor data.
Technical Details of Final DeliverableThe transmitting Raspberry Pi will capture images as well as sensor data and transmit it to intermediate nodes using nRF24l01 module. The data will be passed among nodes so that it reaches the receiving Raspberry Pi at the user end. No internet connection will be used in transmission of data from transmitter to receiver.The receiving Pi will upload the collected data to a cloud database in real time
