The mining safety system ensures the hazard free working environment. The main purpose of the project is to reduce the mining accident and improve the working conditions. IoT based mine safety system has various sensors for several purpose and the Arduino Uno is used for better reliability. All the sensors are together considered as a unit and this system is placed in the mining industry. The various parameters such as temperature and humidity value, light intensity level, poisonous gas level in the air and trace of flame are observed from the working area by the sensors. These sensors values are sent to the Arduino for further process and if the values exceed the threshold level an alert message is sent to the mining control room. In any emergency situations the buzzer is used to alert the workers who are working inside the mining working area. The RF transmitter sends the accelerometer value to the Arduino. The wifi module enables the internet access to the mining safety system. All the sensed values are printed on ThingSpeak website which gives the Application Programming Interface (API) key to interface the system and ThingSpeak. Keywords- Internet of Things, Arduino, ThingSpeak, API key, Mining safety system I. INTRODUCTION Internet of Things (IoT), also sometimes referred to as the Internet of Everything (IoE), consists of all the web-enabled devices that collect, send and act on data they acquire from their surrounding environments using embedded sensors, processors and communication hardware. These devices, often called "connected" or "smart" devices, can sometimes talk to other related devices, a process called machine-to-machine (M2M) communication, and act on the information they get from one another . Humans can interact with the gadgets to set them up, give them instructions or access the data, but the devices do most of the work on their own without human intervention. Their existence has been made possible by all the tiny mobile components that are available these days, as well as the always-online nature of our home and business networks.
