Gas or liquefied petroleum gas (LPG) is a chemical substance resultant from petroleum and could be dangerous in industrial places or those that deal with this substance. Gas leakage causes many health issues. So, to prevent such catastrophes and in order to maintain a clean air environment, the workspace atmosphere should be frequently monitored and controlled. The proposed monitoring gas leakage detector system is based on Internet of Things (IoT) technology. NodeMCU ESP8266 Wi-Fi is used to be the microcontroller for the whole system. The combustible gas sensor (MQ2) is used in order to detect the presence of methane (CH4) and carbon monoxide gas (CO). MQ2 sensor will detect the concentration of the gas according to the voltage output of the sensor and the ESP8266 will send the data reading from the gas sensor to Blynk IoT platform over an IOS phone; data visualization is done using Thingspeak IoT Platform. Besides, a fan will immediately work upon the leakage occurs along with an alarming buzzer.
There are many serious accidents on human life caused by electric current columns, and it is possible for the Internet of Things to find solutions to prevent the risks that occur, as in many fields such as medicine, agriculture, industry and others. In this paper, we will show monitoring and tracking of the current that passes through the electrical poles and the possible leakage, in addition to monitoring the temperature and humidity in the area, and knowing the condition of the light in the column according to morning and evening, this proposed system that will perform a general purpose added to the region. using Open source NODE MCU board, GPS positioning, current sensor, temperature and humidity sensor that provide desired data via open source platforms that we have chosen to be ThingSpeak that easily to handle.
