In this article, Wikipedia has curated a list of interesting-looking topics related to ‘smart sensors’.
Types of Sensors
There are many types of sensors, but this article will focus on six frequently used types of sensor. Each type of sensor has its own advantages and disadvantages, so it is important to choose the right type for the task at hand. 1. Ultrasonic Sensors Ultrasonic sensors are similar to audio sensors except they use sound waves to detect objects. They are good for measuring small distances and can be used in many applications, such as object tracking and motion detection. Ultrasonic sensors can be sensitive to multiple objects and can be difficult to use accurately in a noisy environment. 2. Optical Sensors Optical sensors use light to detect objects. They are good for measuring large distances and can be used in applications such as navigation and security monitoring. Optical sensors can be inaccurate in low light levels or when the object being detected is moving. 3. Magnetometer Sensors Magnetometer sensors use magnetic fields to detect objects. They are good for measuring orientation and movement, which makes them perfect for applications such as automatic car navigation and assisted living. Magnetometer sensors can be inaccurate in strong magnetic fields or when the object being detected is moving quickly. 4. Gyroscope Sensors Gy
Sensors in Action
IEEE Spectrum has a nice overview of smart sensors by Katherine Bourne. There are a lot of cool things happening with these sensors and it’s going to be interesting to see what comes next.
Smart sensors are small pieces of hardware used in a variety of applications, including environmental monitoring, safety and security, agricultural production, and manufacturing. By connecting to the internet or other networks, smart sensors can collect and exchange data wirelessly.
