GSM based Industry Protection System

With heavy automation taking place these days, the number of industries as well as number of accidents in those industries have increased substantially. Human errors and manual safety systems lead to increase in industrial accidents. So here we propose a gsm based industrial protection system that detects smoke, temperature as well as light to keep track of accidents. The system needs to detect if the temperature of a machine or environment goes above a certain level, if it goes above a level, it is an indication of a malfunction. So here we use temperature sensor to detect a possible accident. Next indication is the malfunction or overloading of machines leading to smoke. We use smoke detectors to detect smoke and similarly a light sensor to detect light due to spark or any flash caused due to malfunctions. All these indicators/sensors constantly provide their input to the microcontroller connected to them. The microcontroller constantly processes this data. On encountering a warning signal from any of these sensors the microcontroller now communicates this data to a gsm modem interfaced to it and sends out an SMS message to intended user as a warning.

Alcohol Sensing Display With Alarm Project

We here propose an alcohol sensing system that measures alcohol intake, displays percentage of alcohol and also sounds an alarm if it is above a particular threshold. Here we use an alcohol sensor circuit along with lcd display and a buzzer alarm. Our system first uses the alcohol sensor in order to detect alcohol. The sensor provides analog output. This analog output is now provided to the microcontroller for further processing. Based on the input the microcontroller calculates the percentage of alcohol and displays the same on an LCD display. It also sounds an alarm if the amount of alcohol exceeds a particular amount. Our system thus allows to measure amount of alcohol and then display percentage of alcohol measured. Also a alarm is sounded that indicates that measured alcohol is above a particular percentage.

CNG/LPG Gas Accident Prevention With Gsm Alert

Gas leakage tragedies and accidents have lead to heavy losses over the years. So it is very important to detect any gas leakage and prevent any accidents. So we here propose a system to detect LPG/CNG gas leakage scenarios and provide a security alert to intended users. We here propose to build the system using a MQ6 gas detection sensor and interface it with Avr family microcontroller along with gsm modem for alerting through buzzer. Our system uses the gas sensor to detect any gas leakages. The gas sensor sends out a signal to microcontroller as soon as it encounters a gas leakage. The microcontroller processes this signal and sends out a signal buzzer and LCD with required message details.

Home And Industrial Safety Using Fire And Gas Detection System

Gas leakages and fire outbreaks in industries as well as houses have lead to wide destruction and losses in the past. Gas leakages and fire outbreaks both spread widely and lead to even greater loss of life and property if proper action is not taken on time. So here we propose a system that detects gas as well as fire outbreaks and alert us accordingly so that proper action may be taken to control it. For this we system we use a gas sensor along with a temperature sensor interfaced to the microcontroller. The microcontroller is also in turn connected to an LCD screen and a buzzer to show the alerting part. As soon as a fire starts the rise in temperature is recorded by out temperature sensor. When temperature rises beyond a certain limit it sends a signal to the microcontroller the microcontroller processes the signal and displays the fire alert status on LCD screen and also sounds the buzzer. Now the gas monitor too constantly monitors for any gas leakage. As soon as any gas is detected at the sensor it sends a signal to the microcontroller. The microcontroller now processes this data and sounds the buzzer and also displays the gas alert message on the LCD screen.

Machine Overheat Detection With Alert

This proposed system is used to detect temperature of devices that are overheated. This project is very beneficial especially in places like factories or industries consisting of big machines where it is very necessary to take some action in case the machine is overheated. The system uses a digital temperature sensor in order to detect temperature and pass on the data to the microcontroller. The 8051 microcontroller processes data and sends the temperature to be displayed on LCD screen. The display consists of 7 segment display unit to display up to 3 numbers. It consists of 4 push buttons for setting the high and low temperatures. Pressing set button allows user to increment and decrement the temperature of the system. The system uses 12V transformer to supply power to the system. We can set a limit to the temperature and in case if the system exceeds the temperature limit, an alarm rings to indicate that the system has exceeded the set temperature.
