This project will describe the construction of our portable parking sensors.

Data from ultrasonic sensors, the system will see the LCD screen via bluetooth. Our system will provide benefits across the board is very simple to carry and install. When we want to we can arrange another vehicle from a vehicle.

Step 1: Materials:

2 Arduino (no matter nano models will suffice)
HC-05 and HC-06 Bluetooth Modules
HC-SR04 Ultrasonic Sensor
LCD Display (16 x 2)

The bluetooth module that we use to communicate before we begin our project will need to configure the AT.

You can see how to do it here. >>Communication of the Bluetooth module

Step 2: Transmitter and Receiver Circuit:

The receiver section as the LCD can form connections.

If the LCD screen serial converter you do not need to make this connection.

We use normal contact pins for Bluetooth communication modules of the software. You do not need to add a separate serial communications library.

Step 3: Software Part:

After installing the software, bluetooth modules in the open position when the two systems will automatically connect to each other.

Once connected, you can see from the screen LCD. We set the maximum distance of 200 cm in software. If maximum visual distance of the sensor 4 metredir.ist you can change up to 4 meters.
