Emission Controller in Automobiles Using Black Box project is developed for the users to store and analyze the status of "Co" emitted by vehicles.

It mainly consists of a "Co" sensor and microcontroller unit. The "Co" sensor is connected with the silencer of the vehicle. It senses the amount of "Co" and sends signal to the microcontroller. Frequently the values are stored in the microcontroller.

When the vehicle is supposed to FC, the monitoring device will be connected with the black box. The monitoring device consists of a PC. The PC is connected with the Black box via USART. The software in the PC reads the data stored in the black box.

If the data stored is normal, the vehicle will be allowed for FC. Thus it is very easy to check the status of the vehicle while inspecting it.

Since microcontroller is used, the operations are very sensitive. This can be easily implemented in vehicles


The status of the "Co" is stored continuously.

In the time of FC, the data can be restored which helps to find out the amount of "Co" dissipated
