Result and analysis :

Maxsonar-EZ1

The Maxsonar-EZ1 sensor offer a very short to long range detection which is from 0-inches to 254-inches plus with a very low power consumption. It has provided sonar range information from 6-inches out to 254-inches with 1-inches resolution. Object from 0-inches to 6-inches are range as 6-inches. It has 3 modes selection for the output range which is:

~ Serial, 0V – 5V, 9600 Baud
~ Analog, 10mV/inch
~ Pulse Width, 147us/inch

EUART of PIC16F887

The Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) module is a serial I/O communication peripheral. It is also known as Serial Communications Interface (SCI). It contains all clock generators, shift registers and data buffers necessary to perform an input or output serial data transfer independently of the device program execution. As its name states, apart from the usage of clock for synchronization, this module can also establish asynchronous connection, which makes it irreplaceable in some applications.

Conclusion :

• Maxsonar-EZ1 will send the output if in ASCII format. For maxsonar-EZ1 sensor, the output are in RS232 format which mean that the HIGH(1) bit are at 0V while the LOW(0) bit are 5V, so need to connect the TX of sensor connect to NPN while RX of sensor to TX of microcontroller as shown in figure above. 

FYP S2 WEEK 2

Content/procedure:

FYP S2 WEEK 1

Tittle of activity :

• 1st FYP briefing

I'm attending the briefing about FYP at Gemilang Hall, UniKL BMI by FYP Committee about the what to do and not to do. Just like the ordinary briefing like last semester that tell the basic thing and just adding the info about Engineering Day's shirt and the new features like this blog so on.

In this week also I got to meet my project supervisor to discussing about the progress of my project. Basically my project had undergo the simulation development but I just complete half of it. The sensor and camera part still in research in order to combine it with the main micro controller. Futhermore, I had bought some of the components to be used in this project.
