IoT based Human Safety System for Coal Mines

Project Description:

1. Arduino Uno: Arduino Uno: The digital and analog input/output pins equipped in this board can be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
2. Wi-Fi Module: ESP8266 Wi-Fi module is generally used to establish the wireless communication between the devices. But this module is not capable of 5-3V logic shifting and will require an external logic level converter
3. Gas Sensor: The sensor which can detect the amount of specific gas level present the air is called Gas Sensor.
4. DHT sensor: The sensor which can detect the temperature and humidity at the same time is called as DHT Sensor.

Project Implementation:

1. Interface the Gas sensor and DHT sensor with the arduino
2. Now calibrate the Gas sensor for specific gas level
3. If that specific gas presence is more than the prescribed limit, immediately a sms will be sent to the respective authorities
4. Similarly the if temperature is higher than the prescribed limit, immediately a sms will be sent to the respective authorities
5. The present status of the gas level in the air and temperature of certain area will be updated in remote server for further server

Software requirements:

1. Arduino IDE : You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board
2. Thingspeak : Also, you need to create an account in the ThinkSpeak IoT platform to integrate the system onto the cloud and store the data online
