This is Traffic Signal for Emergency Vehicles & VIP Vehicles IOT Project.
In this project, we are using Raspberry Pi with connected traffic lights surround the box this will be placed in a three-way Junction
This is the 3 way Junction, whenever the emergency vehicle comes we have 2 tags, incoming tag and outgoing tag, When incoming tag senses wherever the signal is the signal transition will be happening to the box and green light will on.
When green will stop is that means the vehicle is moved away.
In this project we are using RFID Tag, this is used to sense the RFID tag, whenever the ambulance sees the RFID tag, and this will give serial data to NodeMCU.
NodeMCU send data over MQTT protocol to Raspberry pi saying that Switch on the green light on the particular root till it senses another tag.
Check the below project output video, this is how emergency alerting is happening in the traffic signal.
This main & objective of this proposed project work is an attempt to design an advanced vehicle security application that can identify vehicle accident detection and fire detection alert can send the details over GSM to authorized persons.
In present existing security models, there is no such automation system which will send alert to the user when an accident is meet or if it gets caught with fire. It is very difficult to identify the vehicle in this situation.
We are proposing the new security system for 4 wheelers, which will have given security to the vehicle. In this system, the vehicle will have Position sensor and bump sensors inside the car to detect the vehicle accident and we have a temperature sensor to detect engine overheating and alert the user in the car with buzzer sound and an alert is sent over GSM module.
The entire security system is controlled with Arduino UNO board. This complete system is designed taking into consideration the low range vehicles to provide them extreme security.

8051 Micro Controller Description:
Microcontroller is the single chip based device that contain memory, CPU, RAM and ROM. They also contain clock and they control the input and output signals. They are also called computer chip.Every device and products today work on the microcontroller; they are embedded with millions of products. They are used in the appliances and even in the vehicles. A single car has more than 50 microcontrollers.
AT89S52: they are the 8 bit microcontroller with 8k bytes of the available memory flash memory. They are high performance and low power consuming microcontroller. They are developed using the Atmel technology that create nonvolatile memory and they are compatible with the standards of industries. They uses flash memory, it means that they can be re-programmed.
They are made up of monolithic chips. They are less costly and flexible. They have 256 bytes of RAM and they have 32 inputs and output with timer that is based on the watch dog timer. They have two data timers that have three 16-bit timers, and six vectors interrupt architecture. They have serial port that is full duplex and oscillators and clock circuitry. They are based the static logic for performing operations. They have Idle that stops the CPU but the RAM, timers and counters are still working.
Introduction to GSM Based Home Security System Project:
When we talk about the security the one thing come in mind that whether our home is secure or not. It is must to secure our home first then look at other things. Our home has always important documents, money and other precious things, that need to be protected from the intruders or thieves. We also need to protect the home from fire and gas leak as they can also destroy our home. We can use security device at our home that will warn us from any harm by alarm or sending SMS to cell. We can use 8051 micro controller or 89s52.
GSM Based Home Security System Project Block Diagram:
They are low power chips. They are high performance chips with 8 bit and they is flash memory for storing data.This flash memory allows them reprogram when required. Flash are made up of monolithic chips as they are highly flexible and loss cost. They consist of 32 I/O lines, timers, pointers, oscillators, and clocks etc.
For this microprocessor we use the software called Kiel u- version. This provides tools for the development of the software of the 8051. With the help of this we can generate embedded applications. They use the protocol command named as AT command. They receive the message comes from the phone, then decode the SMS, authenticate the number. Then use their ports to control the specific appliances and after the operation send the feedback to the users for the confirmation.AT command sets are used for the GSM service to connect the device with the mobile phones.
Functions: they have internal RAM and ROM. Input output ports for programming, timers and counters, 8 bit status words. They contain two 16 bit timers with 4 banks of registers. The RAM used has the memory of 128 bytes. 80 bits are assigned for the general purpose of data memory.
