Many fire situations have represented the loss of lives and material costs due to the lack of early fire detection through smoke or gas sensing, which can become complex and critical Meanwhile, engineers worldwide develop and test multiple systems for smoke and gas detection, commonly based on sensor networks, digital image processing, or computer vision Furthermore, the detection system must work thoroughly with alarms and warnings that aware of a risk situation for prompt evacuation of the population in the surroundings based on a reliable data network topology with adequate device deployments that will let us know the moment a fire outbreak This paper presents a low-cost Internet of Things (IoT) prototype for fire detection in outdoor environments based on sensors and Low Power Wide Area Network (LPWAN), focused on the accuracy in the temperature and gas measurement at the moment a fire starts For its achievement, we integrated wireless components, development boards, and electronic devices, following the management of information updates through a database schema for the alarm settings based on the data gathered from the sensors

LPWAN Based IoT Surveillance System for Outdoor Fire Detection

Now Technology has spread in every field of our lives. In present era, Everybody is having some kind of connectivity with technology whether in form of mobile, laptop or others. Here we are going to discuss the use of technology in field of home security. In this system, we are using ARDUINO UNO microcontroller board. This system is based on door lock security with the help of 2 high level security passwords and simultaneously the system would be connected with owner’s mobile phone through GSM Module So that the owner could open the door from remote location also. When any authorized would try to open the door, he would have to enter 2 passwords when asked to do so. If he enters right passwords then the door will get open. But in case, he enters any of the two or both passwords wrong then the system would get alert and send a message to the owner to ask him whether it is he or not and work accordingly. This system will be guard to Homes, Shops, Banks and institutions etc.

This work focuses on exploiting the IoT (Internet-of-Things) technology by measuring certain physical like parameters and getting that data over a cloud. The data can be stored in realtime and could be monitored on ThingSpeak Channel which is an open source cloud platform. In this project work, a dedicated ThingSpeak channel was created by the user for this purpose. The parameters measured were temperature and humidity only and an integrated due point, humidity, temperature measurement sensor DHT11 was deployed for the purpose. The system reads and transmits the measured data wirelessly using Wi-Fi protocol through ESP8266 enabled NodeMCU board. Hence the communication established between NodeMCU and ThingSpeak platform is through a local hotspot Wi-Fi network established by the user. The code has been edited and compiled in the Arduino IDE and the working hardware prototype will validate the work.

Implementation of an IoT based Real Time Signal Acquisition System over the Cloud using ThingSpeak Platform for Multi-Zonal Temperature & Humidity Measurement

In last few decades, it has been seen that smart devices are taking over a lot of domains like entertainment, automotive, and health care. With all these smart devices, the main objective is to make the existing devices capable of doing much more than they are currently capable of, thereby making the lives of the users easier. The proposed smart inhaler system is an add-on to the traditional inhaler systems which can benefit the patients using modern-day technologies. The smart inhaler system consists of a piece of hardware, built on a thumb-sized development board, and an application that communicates with the hardware via Bluetooth and enables the patients/users to interact with the hardware. The proposed inhaler system not only performs the primary tasks of recording the inhaler usage and the remaining count but has a lot more to offer like keeping track of the usage in periods of weeks or months which assists in finding a suitable medicine for the patient. Furthermore, the proposed system is capable of monitoring, storing, and processing various analyzable data units. With the knowledge of parameters at hand, it becomes feasible to establish the cause of the attack and set some ground rules for preventing such a case in the future, also allowing for this data to be stored in a timely report format. Additionally, in an effort to solace the patient during an emergency or an attack, a handy emergency functionality is provided which alerts the patient’s relative and the nearby hospital, proving to be a life-saving feature. To top this all, the said application also establishes a path for easier interaction between the patient and the doctor using the provided ‘Doctors Network’ functionality. 

IoT-Based Intelligent Inhaler System with Temperature, Oximetry Measurement, and Emergency Functionality

Now a days, Home Security threat is the most challenging task in our life. To overcome this threat, our houses must be Smart. We can make our home Smart and secure. The technology gives us the opportunity to increase the connectivity of various devices hence we can get an overall security solution. Moreover, as the area of GSM Mobile is widening, we can remotely control and monitor the network enabled devices. The device can also send signal to the remote person whom we want to notify about the threat. The use of this system would be user-friendly, flexible and cost effective. GSM technology is simple, flexible and very reliable to use. Designed for global market, SIM800 is a quad-band GSM/GPRS module that works on frequencies GSM 850MHz, EGSM 900MHz, DCS 1800MHz and PCS 1900MHz. SIM800 features GPRS multi-slot class 12/ class 10 (optional) and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. With a tiny configuration of 24*24*3mm, SIM800 can meet almost all the space requirements in users’ applications, such as M2M, smart phone, PDA and other mobile device. It is broadly used transceiver standard.
