ent and similarly the other pair is fixed at down side of the train direction. Sensors are fixed at 1km on both sides of the gate. We call the sensor along the train direction as Ëœforeside sensorâ„¢ and the other as Ëœaft side sensorâ„¢. When foreside receiver gets activated, the gate motor is turned on in one direction and the gate is closed and stays closed until the train crosses the gate and reaches aft side sensors. When aft side receiver gets activated motor turns in opposite direction and gate opens and motor stops.

unchanged. F.M is also better able to transmit sounds in stereo than A.M. Commercial F.M broadcasting stations transmit their signals in the frequency range of 88 megahertz (MHz) The project is designed using F.M COMMUNICATION to avoid railway accidents happening at unattended railway gates, if implemented in spirit. This project utilizes two powerful IR transmitters and two receivers; one pair of transmitter and receiver is fixed at up side (from where the train comes) at a level higher than a human being in exact alignment and similarly the other pair is fixed at down side of the train dire..................[:=> Show Contents <=:]

he departure of the train is detected by sensors placed at about 1km from the gate. The signal about the departure is sent to the microcontroller, which in turn operates the motor and opens the gate. Thus, the time for which the gate is closed is less compared to the manually operated gates since the gate is closed depending upon the telephone call from the previous station. Also reliability is high as it is not subjected to manual errors.

T DEPENDENT RESISTOR
6.1 Description:
This practical is about using a light dependent resistor (LDR) as a sensor. The LDR must be part of a voltage divider circuit in order to give an output voltage, Vout , which changes with illumination.
A light dependent resistor is a resistor whose resistance decreases with increasing incident light intensity. It can also be referenced as a photo conductor. An LDR is made of a high resistance semiconductor. If light falling on the device is of high enough frequency, photons absorbed by the semiconductor give bound electrons enough energy to jump into th..................[:=> Show Contents <=:]
