IoT based wearable device using WSN technology for miners

Safety is of great importance in mining regions. An IoT based wearable device inculcating the safety features for mine workers is developed. It consists of helmet module and the base station module. Sensors used in this wearable device are the temperature sensor (DHT11), humidity sensor (DHT11), gas sensor (MQ4) and collision detection sensor (SW420). The various quantities monitored are communicated by wireless Sensor Network (WSN) technology. Helmet detection circuit checks for the presence of the device. The base station module consists of personal computer having access to the cloud. An IoT platform is used to update the real time data to the cloud, which can be accessed from anywhere around the restricted area. Miner is alerted using Organic LED (OLED) for temperature as well as humidity monitoring while a buzzer alert is made available to detect the gas level in the mine. Communication is through the inbuilt wi-fi of the controller. A notification alert is sent to the supervisor if any unusual situation is encountered. Thus a wearable device incorporating the various sensors, alerting mechanism and communication system is developed to enhance safety of the miner.
