The gas leakage alarm circuit operates off a 9V PP3 battery.
Zener diode ZD1 is used to convert 9V into 5V DC to drive the
gas sensor module. A preset in the module is used to set the
threshold. Interfacing with the sensor module is done through a
4-pin SIP header.
Whenever there is LPG concentration of 1000 ppm in the
area, the OUT pin of the sensor module goes high. This signal
drives timer IC 555, which is wired as an astable multivibrator.
The multivibrator basically works as a tone generator.
Output pin 3 of IC 555 is connected ....etc

This project is developed using 8051 microcontroller, to avoid railway accidents
in automatic mode the railway gate, if implemented in the spirit. This project
uses two powerful IR transmitter and two receivers. one pair of transmitter and
The receiver is installed up-side (where the train runs) at higher levels than
a human being is precise alignment and is similar to the other couple is fixed on the underside of the
in the direction of the train. Sensor activation time is adjusted by this time calculation
taken with a certain speed ....etc

pcb layout for vehicle tracking system using gps and gsm modem

In Vehicle tracking project, you can track the location of your Vehicle. This project gives Minute-by-minute updates about vehicle location by sending sms through GSM modem. This SMS contains longitude and latitude of the location of vehicle. Microcontroller is the central processing unit CPU of our project. Microcontroller gets the coordinates from GPS modem and then it sends this information to the user in Text SMS. GSM modem is used to send this information via SMS. SMS will be ....etc
