Smartphones are equipped with many different sensors that allow us to interact with our real-world surroundings. However, our growing dependence on smartphones is generating considerable new threats, owing to the army of sensors that are increasingly vulnerable to attack. Ever...
In this video, the presenter will show you how to build a motion based sensor that will send you an alert anywhere in the world via Email or a text message. And above all, this project can be built...
Biosensors are analytical devices that combine a bioreceptor (biological recognition element) and a transducer. The bioreceptor can be organisms, tissues, cells, enzymes, antibodies, nucleic acids, etc. It detects the target analyte. The transducer can be electrochemical, optical, thermal or...
Availability of real-time data and reliable transmission from the sensor to the receiver are crucial for medical, nuclear and autonomous vehicle applications. This article details how sensors meet the requirements of such applications. Sensing technology is evolving at a very...
Microwave sensors offer great advantages in security and energy savings with their high sensitivity Microwave sensors are cost-effective solutions to save energy expenses and secure premises of businesses. Their most popular use is in lighting, where these can save up...
Different types of applications require different types of sensors to collect data from the environment. This article takes a look at some common IoT sensors In an Internet of Things (IoT) ecosystem, two things are very important: the Internet and...
The pressure sensor is also termed as a pressure transducer or pressure switch. Depending on the type of output interface, pressure sensors are classified as analogue and digital. A pressure sensor may also be called a different name (such...
Never has the physical fitness training been so interesting before. From visualising streets of different countries while cycling to adjusting the resistance of the bicycle, virtual reality (VR) is bringing fun and intelligence to physical activities. Not only the VR...
Thermopile temperature sensors offer the advantage of non-contact temperature measurement, which has made them more popular than traditional contact-type temperature sensors. These sensors use infrared (IR) radiation for heat transfer, and are commonly used in portable devices such as...
Before working with sensors on any project, we must know its usage, advantages, limitations and characteristics. There are various parameters on which a sensor is chosen for any particular application like cost, size, weight, resolution, sensitivity, etc. In this...
