Basic Sensor To Connect With Arduino For Students.(PART -1)
What Is An Arduino?
Arduino Is An Open Source Electronic Platform That Can Be Used To Learn Both Hardware And Software. It’s a single-board microcontroller that can be used to create digital devices.
With Arduino, we can create thousands of projects.
By connecting sensors, it can provide input to the board and display the result output, or you may view the output on your own computer.
To learn Arduino and complete projects, you’ll need a laptop or computer.
Arduino Software is used to provide inputs to the board (IDE).
Before we go on to sensors, we must first understand how they function and how to programme them using Arduino software.
We can begin with the basics, and then you can show interest in Arduino projects.
You must first take your Arduino board and LED.
Install the Arduino IDE programme on your computer.
You must select your board type based on your Arduino board type. To begin, go to software and select tools options. From there, you may select board (the default board is “Arduino UNO”) and adjust the board type
Follow these steps to code your board:
step 1: Go to the file menu and select example.
step 2: You see Basics and press the blink button.
step 3: Using an Arduino cable, upload your blink code to the Arduino boar
Place the LED in the Arduino as shown in the diagram.
Now we can see sensors and its working
IR SENSOR :
It’s an electrical device that detects and measures infrared radiation in its immediate environment.
In the year 1800, an astronomer named William Herchel made an unintentional discovery.
Because the wavelength of infrared light is longer than that of visible light, it is invisible to the human eye (though it is still on the same electromagnetic spectrum).
There are two types of infrared sensors: active and passive.
Active infrared sensors have two parts: they emit and detect infrared radiation.
A light emitting diode (LED) receiver is a device that receives light from a light emitting diode (LED).
When an object approaches the IR sensor, the LED’s infrared light reflects off of it and is recognised by the receiver.
It functions as a proximity sensor and is widely utilised in obstacle detection systems (such as in robots).
It has a wavelength of 780nm.
ULTASONIC SENSOR :
It looks a lot like bats. How does it manage to fly?
It emits sound in the opposite direction, allowing it to detect any impediments.
An ultrasonic sensor is an electronic device that uses ultrasonic waves to detect distance from an object and converts the reflected sound into an electrical signal.
It waves travel at a faster rate than audible sound.
Ultrasonic sensors are separated into two parts:
The transmitter (which uses piezoelectric crystals to create sound) and the receiver (receives signal from the target).
It is quite accurate. For broad detecting areas, the ultrasonic sensor HC-SR04 or HY-SRF05 is typically used.
It is used not just to measure linear distance, but also to determine its position in the X/Y plane.
It has a range of 2-400cm with good precision.
