Advertisement
This page describes a list of sensors used in Arduino board-based projects. The Arduino Sensors list covers temperature, humidity, ultrasonic, sound, water, collision, color, and wireless-related sensors used in Arduino board-based projects.
About Arduino Board
- It is a microcontroller-based board which uses the ATmega328 microcontroller chip.
- It has 14 digital input/output pins out of which 6 pins can be used as PWM, 6 analog inputs, a 16 MHz crystal, a USB port and power jack, an ICSP header, and a reset button.
- It is easy to program using a computer after connecting it using a USB cable.
- It can be powered ON either using a USB cable, power adapter, or battery.
Arduino Board
It is used for a wide variety of applications including 3D printing, wearable devices, IoT applications, and more. Many sensors can be interfaced with the Arduino board as per various applications such as temperature/humidity monitoring, motion sensing, distance measurement using ultrasonic waves, heart rate sensing, water level sensing, flame sensing, gas sensing, color sensing, and so on.
About Sensors
A sensor is a device that detects a change in some parameters and converts it into a measurable signal that can be used for some purpose. As it converts one parameter to another, it is also known as a transducer.
For example, a thermistor, which is basically a temperature sensor, can be used to measure change in temperature by detecting change in resistance. A motion sensor is used to sense the motion of an object or person. Motion sensors are mainly of two types, viz. active and passive, based on their working principle.
A sensor or transducer converts one form of energy into another form of energy.
Arduino Sensors List
The following table mentions the Arduino sensors list along with a description and link for further study.
| Arduino Sensors | Functional Description |
|---|---|
| Temperature and Humidity Sensor | This sensor type is used to measure ambient temperature or humidity, and Arduino takes the data and displays or performs some desired function as per programming done by the user. An LCD can be interfaced with the board in order to display these parameters i.e. temperature and humidity. |
| Ultrasonic distance sensor | It transmits sound waves at ultrasonic frequency towards an object and receives the reflected echo. It measures the distance of the object from the sensor by comparing the received echo with the transmitted signal. This sensor is used with Arduino in automatic car parking systems, robot design, and so on. |
| Infrared emission sensor | This is used for remote controlling applications such as controlling a TV or another Arduino board. |
| Sound sensor | This sensor type is used to sense surrounding sound and is used for voice changer projects. |
| Optical sensor | Sensing of light is known as optical sensing. The sensor used for optical sensing is known as an optical sensor. An optical sensor converts light rays into electrical signals. It uses a photo-resistor for its operation. |
| Gas sensor | Various types of gas sensors are used for the detection of different gas types. It converts chemical information in the gas into measurable electronic signals such as voltage, current, or frequency. These sensors are useful to measure emission levels of gases which are essential to keep them within limits for the safety of human beings. |
| Water sensor | There are different water sensors used for water level sensing and water flow rate sensing. |
| Line follower sensor | This sensor type is used to track the line. It can track a white line in a black background or a black line in a white background depending upon programming and the use of sensors on the Arduino board. |
| Motion sensor | There are two types of motion sensors viz. active and passive which are used for sensing the motion of an object or person. |
| Wireless sensor | There are various sensors used for wireless applications such as RFID, Zigbee, Zwave etc. . |
| Color sensor | The sensor device which does color sensing is known as a color sensor. It works based on the principle of wavelength identification of different colors. Color sensor-based systems are used for quality control applications in the textile industries. |
| Light intensity sensor | It is used to measure light intensity in units of lux in the range from 0.1 to 40K lux. |
| Barcode reader or scanner module | There are barcode readers or sensors interfaced with the Arduino board. |
