Here are IoT interview questions for fresher also as experienced candidates to urge their dream job.
Top 10 IoT Interview Questions and Answers:
1) what is the internet Of Things (IoT)?
Internet of Things is a network of associate smart devices give rich data,however it can also be a safe nightmare . The goal of IoT is to increase to internet connectivity from standard devices like computer, mobile, tablet to relatively dumb devices sort of a toaster.
2) Explain Raspberry Pi
Raspberry Pi may be a computer which is capable of doing all the operations sort of a conventional computer. it’s other features like onboard WiFi, GPIO pins, and Bluetooth so as to speak with external things.
3) How to run Raspberry pi in headless mode?
Raspberry pi in headless mode are often travel by using SSH. the newest OS has an inbuilt VNC server that’s installed for taking remote desktop on Raspberry Pi.
4) What are the elemental components of IoT?
The four fundamental components of an IoT system are:
a)Sensors/Devices: Sensors or devices are a key component that helps you to gather live data from the encompassing environment. All this data may have various levels of complexities. It might be an easy temperature monitoring sensor, or it’s going to be within the sort of the video feed.
b)Connectivity: All the collected data is shipped to a cloud infrastructure. The sensors should be connected to the cloud using various mediums of communications. These communication mediums embrace mobile or satellite networks, Bluetooth, WI-FI, WAN, etc.
c)Data Processing: Once that data is collected, and it gets to the cloud, the software package performs processing on the gathered data. This process are often just checking the temperature, reading on devices like AC or heaters. However, it can sometimes even be very complex, like identifying objects, using computer vision on video.
d)User Interface: the knowledge must be available to the end-user in how , which may be achieved by triggering alarms on their phones or sending them notification through email or text message. The user sometimes ability need an interface which actively checks their IoT system.
5)What are the disadvantages of IoT?
The disadvantages of IoT are:
a)Security: IoT technology builds an ecosystem of connected devices. However, during this process, the system may offer little authentication control despite sufficient cybersecurity measures.
b)Privacy: the utilization of IoT, exposes a considerable amount of private data, in extreme detail, without the user’s active participation. This creates many privacy issues.
c)Flexibility: there’s an enormous concern regarding the pliability of an IoT system. it’s mainly regarding integrating with another system as there are many diverse systems involved within the process.
d)Complexity: the planning of the IoT system is additionally quite complicated. In addition it’s deployment and maintenance also not very easy.
e)Compliance: IoT has maintain own set of rules and regulations. However, due to its complexity, the task of compliance is sort of challenging.
6) Define Arduino
Arduino may be a free electronics platform having easy to use hardware and software. it’s a microcontroller capable of reading input from sensors to regulate the motors programmatically.
7) List mostly used sensors types in IoT
Mostly used sensor types in IoT are:
d)Motion detection sensors
8) Mention the essential difference between IoT and sensor businesses?
A sensor business doesn’t need a lively internet connection to figure . Internet of Things requires an impact side to figure .
9) What are the benefits of IoT?
Key benefits of IoT technology are as follows:
a)Technical Optimization: IoT technology helps tons in improving techniques and making them better. for instance , with IoT, a manufacturer is in a position to gather data from various car sensors. The manufacturer analyses them to enhance its design and make them more efficient.
b)Improved Data Collection: Traditional data collection has its limitations and its design for unresisting use. IoT facilitates immediate action on data.
c)Reduced Waste: IoT offers real-time information resulting in effective deciding & management of resources. for instance , if a manufacturer finds a problem in multiple car engines, he can track the manufacturing plan of these engines and solves this issue with the manufacturing belt.
d)Improved Customer Engagement: IoT allows you to enhance customer experience by detecting problems and improving the method .
10) What are the foremost common IoT applications?
The most common IoT applications are:
a)Smart Thermostats: Helps you to save lots of resources on heating bills by knowing your usage patterns.
b)Connected Cars: IoT helps automobile companies handle billing, parking, insurance, and other related substance automatically.
c)Activity Trackers: Helps you to capture pulse patterns, calorie expenditure, activity levels, and skin temperature on your wrist.
d)Smart Outlets: Remotely turn any device on or off. It also allows you to trace a device’s energy state and obtain custom notifications directly into your smartphone.
e)Parking Sensors: IoT technology helps users to spot the real-time availability of parking spaces on their phones.
f)Connect Health: The concept of a connected healthcare system facilitates real-time health monitoring and patient care. It helps in improved medical decision-making supported patient data.
