in this project we will instal a GSM modem in front of any railway corssing . it will sense railway crossing open or close. then our system will give message to our system. it will sens message to particular number from sim1 via gsm modem. Arduino will work as ac controller in this unit. in the receiver side we will use again gsm modem with sim2 , which will receive message open or close. this sim 2 will give message to arduino 2 at receiver side. arduino 2 will display that message on LCD display or LED display.
LCD use 16×2
arduino Uno 3
sim – 2nos
GSM modem – sim 300/900
USE of project- project can be used for traffic routing if railway crosssing is closed or open then our system will sense railway crossing position and will display phatak open or close at pre location so that emergency vechilces should not face difficulties near railway crossing
