Abstract- Earthquake early-warning systems detect the first quivering of a major quake, triggering alarm systems in advance of the most violent shaking. The Alert system that has been proposed for all over the world would use a network of digital seismometers deployed around the state to give populated areas up to a minute of advance warning (depending on the location of the epicentre). The alerts would allow businesses, residents and public agencies time to get ready. The purpose of the study focuses on the sensor data to decide if an earthquake is occurring. Finally experimental results are provided showing that the system will support the expected performance with the sensor data. A possible extension of the approach could be implementing one wireless sensor networks using thinkspeak for data acquisition.

Although an earthquake, happens, we should first grasp the range and earthquake is totally unpredictable, this research presents sinuousness of the damaged areas for supporting the a real-time and economic countermeasure to this natural rescue activities. For collecting the information around hazard. Through opportunistic applications and online the damaged areas widely and rapidly, the aerial images services into SPs is possible to monitor a whole area, are useful. In our previous study [l], we have proposed learn their physical characteristics, and most important, the method of detecting the damaged areas before the detect seismic movements to raise early warnings in earthquake and after the earthquake. In the method, two order to provide extra time for making better decisions. images are registered manually, and hence, it is Just to mention, the seismic activity is increasing, and troublesome for detecting the damaged areas taken by consequently the risk that it occurs also is of interest; so various locations. In many methods of detecting the that in April 2014 there was a world record number of damaged areas are not automatically registered. In this large earthquakes greater than 6.5. paper, we propose a new method of automatic detection of the damaged areas. The damaged areas are detected METHODOLOGY automatically and displayed graphically on thinkspeak webpage by our proposed method. The combining of the EXISTING SYSTEM sensors accelerometers, gyroscopes, GPS, etc. and the different connectivity options allows to have well- As soon as an earthquake is detected, the equipped IoT devices on our hands and, through these, microcontroller activates a relay that cuts off electricity automatically monitor our movements, locations, and supply. It also sends pulses to a servo motor attached to workouts throughout the day; and beyond that, it can be the gas valve which rotates in order to turn a gas valve the key to the solution of problems in other areas as off, cutting off gas supply. If there is no earthquake event transportation ,medicine , weather , social , or the but a gas leak is detected, then the microcontroller seismology, that is the field our research focuses; and platform simply turns off the gas supply[2].

Welding power supply Uses electricity to melt the surfaces of the metals in order to join them together through coalescence. The electricity is provided by a welding power supply, and can either be AC or DC. Arc welding typically requires high currents typically between 100 and 350 amperes. Some types of welding can use as few as 10 amperes, while some applications of spot welding employ currents as high as 60,000 amperes for an extremely short time. Older welding power supplies consisted of transformers or engines driving generators. More recent supplies use semiconductors and microprocessors reducing their size WORKING: and weight.

The internet is basically an informal term for the world-wide communication network of computers more specifically called the network of networks. Internet not only links computers but also people through them. It was primarily designed to share information between networks. In today’s world people use internet for a variety of reasons: from browsing for information to chatting and even online services like shopping, banking, video conferencing and so forth. As the years progress, the services provided by the Internet grows endless. The “Internet of Things” refers to the concept that the Internet is no longer just a global network for people to communicate with one another using computers, but it is also a platform for devices to communicate electronically with the world around them. IoT represents the next evolution of the Internet, taking a huge leap in its ability to gather, analyse, and distribute data that we can turn into information, knowledge, and, ultimately, wisdom. There are a variety of IoT platforms like Thingspeak, Grovestreams, Thingworx, Xively and so on which provide IoT services to the users for a price.

The idea behind Google assistant-controlled Home automation is to control home devices with voice. On the market there are many devices available to do that, but making our own is awesome. In this project, the Google assistant requires voice commands. Adafruit account which is a cloud based free IoT web server used to create virtual switches, is linking to IFTTT website abbreviated as “If This Than That” which is used to create if else conditional statements. The voice commands for Google assistant have been added through IFTTT website. In this home automation, as the user gives commands to the Google assistant, Home appliances like Bulb, Fan and Motor etc., can be controlled accordingly. The commands given through the Google assistant are decoded and then sent to the microcontroller, the microcontroller in turn control the relays connected to it. The device connected to the respective relay can be turned ON or OFF as per the users request to the Google Assistant.

Email: [email protected] Received: 15 January 2021; Accepted: 17 February 2021 Abstract: Wireless sensor network (WSN) is considered as the fastest growing technology pattern in recent years because of its applicability in var- ied domains. Many sensor nodes with different sensing functionalities are deployed in the monitoring area to collect suitable data and transmit it to the gateway. Ensuring communications in heterogeneous WSNs, is a critical issue that needs to be studied. In this research paper, we study the system performance of a heterogeneous WSN using LoRa–Zigbee hybrid communi- cation. Specifically, two Zigbee sensor clusters and two LoRa sensor clusters are used and combined with two Zigbee-to-LoRa converters to communicate in a network managed by a LoRa gateway. The overall system integrates many different sensors in terms of types, communication protocols, and accuracy, which can be used in many applications in realistic environments such as on land, under water, or in the air. In addition to this, a synchronous man- agement software on ThingSpeak Web server and Blynk app is designed.
