Application of measurement of non-electrical quantities (temperature,
distance, humidity and etc.) in industrial sector is quite large. My research
topic is about the method of measurement of these quantities by utilizing a
microcontroller, namely Arduino.
Being an open-source platform Arduino may be used to create electrical
projects. Arduino is made up of two main parts: a hardware programmable
circuit board (also known as a microcontroller) and software, known as an
IDE (Integrated Development Environment), that runs on your computer and
is used to write and upload computer code to the physical board. Popularity
of the microcontroller has grown among those who are just getting started
with electronics. Unlike most prior
programmable circuit boards, the Arduino
does not require a separate piece of hardware (known as a programmer) to
load new code into the board; instead, a USB cable is all that is required.
Furthermore, the Arduino IDE makes programming
easier by using a
simplified form of C++ programming language. Buttons, LEDs, motors,
speakers, GPS devices, cameras, the internet, and even your smartphone
or television may all interact with Arduino. Because of this flexibility, as well
as the fact that the Arduino software is free, the hardware boards are relatively
inexpensive, and both the software and hardware are simple to learn, a large
community of users has contributed code and released instructions for a wide
range of Arduino-based projects.
Sensors are devices that transform a physical quantity into an electrical
quantity, such as light intensity or temperature. The data signal is sent from
the sensor to the Arduino's output pins. The Arduino then records the
information. Sensors differ in functioning and design.
A photoresistor, also known as a light-dependent resistor or photocell, is
the light sensor utilized in this article. It is used to measure the brightness /
illuminance level of ambient light as well as detect light. The sensor owns
two pins which are symmetrical, and since it is a
type of resistor it is not
needed to distinguish these pins.
The resistance of a light photoresistor
decreases when the face of the photoresistor is exposed to more light. As a
result, we can determine the brightness of the ambient light by measuring
the photoresistor's resistance.
