WEEK 6 - FYP I : SENSOR SELECTION

 Date   : 1.12.2023

Venue :

Time   : 3:00 - 5:00 pm

Activity:

For the week six i make a research about the sensor that i will be use for my project. Three sensor was been selected and it consist of speed sensor, vibration sensor, and temperature sensor.

Objective:

i.  To determine the sensor.

ii. To find knowledge of the sensor.

Content :

Figure 1 : Vibration sensor

Figure 2 : Temperature sensor

Figure 3 : Speed sensor

The figure above is the three sensor that will be use. First, the vibration sensor SW-420. Second, the temperature sensor Ds18B20 it suitable to detect heat from the metal. Lastly, speed sensor IR encoder sensor for detect speed rpm of electrical motor.

Here are the information of the three sensor:

Vibration Sensor Module comes with SW-420 vibration sensor, integrated with adjustable sensitivity via on board potentiometer. There are also LED indicators for power and the digital output status on board. It has a simple and straight forward 3-pin interface, VCC, GND and the DO (digital output). It supports 3.3V or 5V power.This vibration sensor module is compatible with any microcontroller that has a digital input, so of course any popular microcontroller such and PIC, Arduino and Raspberry Pi are compatible. A direct interface is essential to using this sensor.

DS18B20 Water Proof Temperature Sensor is the water proof temperature sensor which is able to measure the temperature in liquid. It provides 9 to 12bit centigrade temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of 55°C to +125°C and is accurate to ± 0.5°C over the range of 10°C to +85°C.

This is a basic kit that included an optical beam sensor with both digital and analogue outputs (opto switch, phototransistor). Any microcontroller may be attached to it using the 4-pin header (minimum 3-pin interface).It provides a 0V and 5V(0r 3.3V) output on the DO (digital output) pin and operates from 3.3V to 5VDC. When the beam is obstructed, it outputs a HIGH voltage; when the beam is unblocked, it outputs a 0V value. If there is an obstruction obstructing the sensor, your microcontroller can easily read the 0-5-0V pulse train to ascertain it. If you have a disc, speed detection may also be accomplished. 

Conclusion :

As the conclusion for this week, the three sensor was obtained and clearly to use as my part of project. For this sensor it can be use to detect temperature of the motor, the vibration of motor and the speed of motor.
