Embedded based Industrial Temperature Monitoring Systems using GSM

Abstract: paper describes the design of a simple low cost microcontroller based temperature monitoring system using GSM technique. The temperature monitoring system using GSM undergoes three stages signal conditioning circuit, analog to digital converter and with GSM Modem the message is send to mobile.ADC is used because microcontroller works with digital inputs. GSM modem can be used to send and receive SMS through AT commands. At the transmitter side, the user sends an SMS to the GSM modem using AT commands. The LM35 is an integrated circuit sensor that can be used to measure temperature with electrical output proportional to the temperature. The LM35 sensor is connected to PIC microcontroller and varying temperature is sent to GSM modem, which is simultaneously displayed in LCD. The GSM modem performs the operation of sending message to a particular SIM number .GSM technology provides users with high quality signal and speech channels, giving them access to high quality digital communication at very affordable rates. GSM network operators can provide their customers with cheaper calling and text messing options.

Gsm based gas leakage detection system

Abstract: Gas leakage is a major problem with industrial sector, residential premises and gas powered vehicles like CNG (compressed natural gas) buses, cars. One of the preventive methods to stop accident associated with the gas leakage is to install gas leakage detection kit at vulnerable places. The aim of this paper is to present such a design that can automatically detect and stop gas leakage in vulnerable premises. In particular gas sensor has been used which has high sensitivity for propane (C3H8) and butane (C4H10). Gas leakage system consists of GSM (Global System for mobile communications) module, which warns by sending SMS. However, the former gas leakage system cannot react in time. This paper provides the design approach on both software and hardware.

Microcontroller based digital meter with alert system using GSM

Abstract: The objective of this paper is to design and implement the low cost digital meter using PIC microcontroller, which could be used for monitoring the temperature and humidity of our environment. In this paper, it is focused mainly for our homes. The temperature is measured using LM35 temperature sensor and the humidity is measured using DHT11 humidity sensor. The measured parameters are displayed through LCD screens, normally like a digital meter. Apart from acting as a meter, it performs the function of automated control system which controls the motor driver connected to the fan, based on the temperature sensed using the microcontroller. When the fire catches the home and the sensor values exceeds the limit, an alert SMS will be sent to the person living in the home through the SIM900 GSM module. Also, an SMS carrying the home address will be sent to the fire department which alerts the fire fighters to urge to the location so that they can protect the home from fire. This paper also proposes the idea of automatic humidity controller using dehumidifier controlled by the microcontroller through the relay module. Thus, the proposed microcontroller based automated digital meter model has been discussed in the paper.

LPG Leakage Monitoring and Multilevel Alerting System

Abstract: Liquefied Petroleum Gas (LPG) is an inevitable on e in day-to-day life. LPG is used as a fuel in a ra nge of applications including in heating and cooking appli ances, industrial applications, in vehicles and as a propellant and refrigerant. Due to leakage of LPG, it produces haz ardous and toxic impact for human beings and also f or other living creatures. To overcome this predicament, we need quittance. Thereby, we speculate some solution s to detect the LPG Gas leakage and make alert to the users who are using LPG Gas. In this paper we are using LPG gas sensor for sensing the leakage and produce the result in a udio and visual formats also alerts human via Short Message Service (SMS). The sensor has excellent sensitivity combined with a quick requital time. The sensor ha s also sense iso-butane, propane and cigarette smoke. This paper provides design approach on both software and hard ware.

IoT based Smart Vehicle Ignition and Monitoring System

Abstract: With the advancements in technology, several smart innovations are being introduced by automobile manufacturers across the world to enhance their product portfolio. These can vary from implementing simple solutions such as navigation systems, to more complex ones such as driver assistance systems, which in turn could monitor multiple parameters of the vehicle in order to assist the driver. This paper focuses on one such driver assistance solution which not only intimates the driver on the well-being of his or her car but also adds additional layers of security to prevent vehicular theft. Keeping in mind driver safety, the paper also proposes an idea to prevent the vehicle from starting in case of alcohol consumption by the driver and also incorporates an emergency alert system in case of accidents. A novel accurate method to calculate fuel levels of a vehicle has also been elaborated. This work has been designed and implemented using a Raspberry Pi - Arduino combination and is also highly cost effective.

Large Hall Temperature Monitoring Portal

Abstract: This paper is to describe the implementation of temperature monitoring system for large halls which helps in improving the condition of the surrounding temperature by monitoring the temperature readings using a specified portal. This system includes multiple temperature sensing devices located in different temperature monitoring zones to produce temperature output readings proportional to the corresponding zones. The temperature monitoring system automatically and sequentially collects and records temperature output readings into the database. Besides that, a portal then displays the temperature readings generated by the temperature sensing devices proportional to the corresponding zones together with the technician details that are in-charged for those particular devices. In addition, the portal also displays colour status bars that differentiates the surrounding temperature whether its too hot, too cold or its at optimum state. Being said by that, if the temperature readings exceeds its threshold limits, alert notifications will be sent to the technician’s mobile phone through the BLYNK Application.
