![]() ![]() It works based on principle of wavelength identification of different colors. The sensor device which does color sensing is known as color sensor. There are various sensors used for wireless applications such as RFID, active and passive which are used for sensing the motion of It can track white line in black background orīlack line in white background depending upon programming and use of sensors on the arduino board. This sensor type is used to track the line. Water level sensing and water flow rate sensing. There are different water sensors used for Refer Gas Sensors > for more information. These sensors are useful to measure emission levels of gases which areĮssential to keep them within limits for the safety of human beings. ![]() It converts chemical information in the gas into measurable electronic signals such as Various types of gas sensors are used for detection of different gas types. It uses photo-resistor for its operation. ![]() Optical sensor converts light rays into electrical signal. The sensor used for optical sensing is known as optical sensor. Sensing of light is known as optical sensing. This sensor type is used to sense surrounding sound and is used for This is used for remote controlling applications such asĬontrolling TV or another arduino board. This sensor is used withĪrduino in automatic car parking system, robot design and so on. It measures the distance of the object from sensor byĬomparing received echo with the transmitted signal. It transmits sound waves at ultrasonic frequency towards objectĪnd receives the reflected echo. LCDĬan be interfaced with the board in order to display these parameters i.e. The data and display or perform some desired function as per programming done by user. This sensor type is used to measure ambient temperature or humidity and arduino takes Refer Article on Sensors and Transducers >įollowing table mentions arduino sensors list along with description and link for further study. Sensor or transducer converts one form of energy into another form of energy. Motion sensors are mainly of two types viz. Motion sensor is used to sense motion of object or person. Measure change in temperature by detecting change in resistance. Measurable signal which can be used for some purpose.Īs it converts one parameter to the other it is also known as transducer.įor example, thermistor which is basically a temperature sensor can be used to The sensor is a device which detects change in some parameters and converts it into Motion sensing, distance measurement using ultrasonic waves, heart rate sensing, water level sensing,įlame sensing, gas sensing, color sensing and so on. Many sensors can be interfaced with arduino board as per various applications such as temperature/humidity monitoring, It is used for wide variety of applications including 3D printing, wearable devices, IoT applications and more. It can be powered ON either using USB cable or power adapter or battery.
