Week 5: Research sensors to be used in this project

Objective for this week : To find the correct sensors for my Final Year Project.

For this week i research sensor i want to use in this Final Year Project. I tried to identify the appropriate sensor and how to use these sensors in order to function properly in my project for this time.

In some of my research, I see there are a number of sensor example of sensors is:

1. Temperature sensor
2. IR sensor/ultrasonic sensor
3. touch sensor
4. Proximity sensor
5. Advance sensor technology

Criteria to choose a Sensor is:

1.    Accuracy

2.    Environmental condition - usually has limits for temperature/ humidity

3.    Range - Measurement limit of sensor

4.   Calibration - Essential for most of the measuring devices as the readings changes with time

5.     Resolution - Smallest increment detected by the sensor

6.    Cost

7.     Repeatability - The reading that varies is repeatedly measured under the same environment

For this Final year project i choose Ultrasonic sensor ,Function this sensor i choose is: 

Ultrasonic Application Technology is the thing which developed in recent decades. With the ultrasonic advance, and the electronic technology development, especially as high-power semiconductor device technology matures,the application ultrasonics become increasingly widespread.

• Ultrasonic measurement of distance,depth and thickness.
• Ultrasonic testing;
• Ultrasound imaging;
• Ultrasonic cleaning;
• Ultrasonic welding;

Conclusion:

For this week i research and understand all function sensor and know the important part of sensor for use to my Final year Project for this semester.
