Abstract In the recent past, there has been cases of carbon dioxide leak related incidents and casualties. Carbon dioxide has been recognized as a significant worthy hazard in the industrial environment for about 100 years. low concentrations of carbon dioxide are not harmful, but on a high concentration can affect the respiratory function and the central nervous system. This prompted the development of this carbon dioxide gas leakage detection system as a safety measure to reduce this risk. This carbon dioxide gas leakage detection is developed with an Arduino microcontroller and an MQ-135 sensor for a highly accurate and fast response system. The detection system incorporates an LCD Screen for displaying the status and level of concentration of the gas leakage, a buzzer as an alarm to give audio alerts, indicating and alerting users on the gas leakage, a number of LED lights to indicate the gas leakage status. The system also incorporates a GSM Module which sends SMS alerts and make calls to users during the gas leakage regardless distance. The Arduino microcontroller is programmed using embedded C++ language and all the peripherals connected to it through its pins. When the detector is in normal state, the LED light is lit on Green to show a normal range in concentration of gases and/or absence of a gas leakage. When there is gas leakage, the system transitions into a harmful state. The system displays the status of the gas leakage on the LCD Screen just as other LED lights light up in conjunction with an alarm buzz giving an audiovisual alarm to the monitoring mobile device. Also, the GSM Module sends out SMS alerts and calls to designated users regardless of their distance from the gas leak vicinity to notify them of the gas leak in order to take immediate action to control the gas leakage situation. The gas leakage detection is not only highly accurate but cheap and portable and can be used for industrial and domestic safety.

Rapid technological progress has affected human life in a number of ways because of this fast growth in various fields, still there is a need to incorporate this skill so that we can change life easier for human beings. It is not possible to supply each and every home with LPG through Pipes in our country as construction of LPG is very small. Currently there is a Development LPG cylinder program reservation via IVRS or online that is greatest tough for the uneducated and busy schedulers to book the LPG cylinder beforehand. Next main issue facing users of LPG cylinder is "They are unaware of the status of completing LPG gas" which makes booking the cylinder much more time-consuming, which is mostly inconvenient. For this reason, most of the analphabets are unable to complete the booking, and usually , these phone line telephones are moreover not reachable because of the overcrowded calls or else telephones that are not functioning because of about procedural problems. The advises a program that is automate full LPG cylinder reservation technique without hominoid interference. The device endlessly monitors the heaviness of the cylinder and will automatically send notification to the approved LPG Manager once it exceeds the minimum threshold so that they perhaps distribute the LPG cylinder in step. In conjunction through the Automatic Cylinder Reservation, we have developed a safety measures for the user in which it continually tracks LPG gas leak [1i ]and warns consumer about it.

Gas is one of the needs that is widely used by the community. The use of gas is very much beneficial, for example, such as the use of gas in households and the use of gas in business or industry. However, there are things we must pay attention to when using gas in terms of safety. Because gas is volatile and there is a possibility of gas leakage which can cause a fire hazard. Therefore to reduce the impact of hazards that can be caused due to gas leakage, a gas leak detection device needs to be made using the MQ5 sensor and the status of the hazard level will be displayed through the android application. So that the existence of this tool will make it easier for users to know the level of gas levels and the level of danger of gas leaks. In this system there are 3 (three) levels of danger, namely safe, normal, and dangerous. If the gas level is high and in danger status, the system will provide information on the android application in the form of gas levels, danger levels and alarms. The use of Fuzzy methods in this system can be applied to explore knowledge and decision making, so that the Fuzzy method is applied to be expected to help in calculating the level of danger of gas leakage effectively and safely to use. In designing this system, the author uses the Fuzzy algorithm with the Mamdani method so that it can facilitate obtaining maximum results in determining the level of danger. From the resulting output can be information about the dangers of gas leakage.

Function of this system is to disconnect and reconnect the electricity supply to consumers. The introduction of the GSM technology and particularly the use of hand-held mobile phones has brought the innovative distance communication to remote locations. This utilization of this technology for the remote control of systems and appliances will make life easier, safe and quick from anywhere. GSM module was used for receiving short message service (SMS) from user’s mobile phone that automatically enable the controller to take any further action such as to switch on and off the consumer load at the incoming power supply. The system was integrated with microcontroller and GSM network interface using assembly language. AVR Studio 4 software was utilized to accomplish the integration. The system is activated when user sends the SMS to GSM controller circuit at electric meter consumption panel board. Upon receiving the SMS command, the microcontroller unit then automatically controls the incoming power supply by switching on or off the device according to the user command. In other words, the developed system reads message from the mobile phone and responds to control the devices according to the received message. The system can also give feedback to the user to inform the status of switching operation if such command is received.

This study proposes two prey–predator models with strong and weak Allee effects in prey population with Crowley–Martin functional response. Further, gestation delay of the predator population is introduced in both the models. We discussed the boundedness, local stability and Hopf-bifurcation of both nondelayed and delayed systems. The stability and direction of Hopfbifurcation is also analyzed by using Normal form theory and Center manifold theory. It is shown that species in the model with strong Allee effect become extinct beyond a threshold value of Allee parameter at low density of prey population, whereas species never become extinct in weak Allee effect if they are initially present. It is also shown that gestation delay is unable to avoiding the status of extinction. Lastly, numerical simulation is conducted to verify the theoretical findings.
