An Infrared light emitting diode (IR LED) is a special purpose LED emitting infrared rays ranging from 700 nm to 1 mm wavelength. Different IR LEDs may produce infrared light of differing wavelengths, just like different LEDs produce light of different...
  As water consumption and wastage increases day by day, water scarcity has become a growing concern around the globe. While some irresponsible people are overusing water and wasting it daily, a large population remain deprived of safe drinking water....
This article covers some important sensors used for different deep-sea applications, including civil, military, research, communication, seismic and energy. Mysteries of the deep sea, vastness of the blue waters stretching out to the horizon, and the tremendous potential of the...
Sometimes, after rains, the air feels moist. The water seems to have suspended in the air. However, in certain AC’s you click some buttons and the atmosphere brightens up. How and why does it all happen? Moisture forms up...
There is a very wide variety of industrial sensors available in the market, and selecting the right sensor for an application can be challenging. Industrial sensors cover almost all the sensor categories including proximity, position, velocity, level, temperature, force and...
An accelerometer is an electromechanical device that measures acceleration forces. The forces may be static or dynamic. If you have the amount of static acceleration due to gravity, you can find out the angle the device is tilted at with...
The latest sensors, including those used in IoTs and wearables, are soon going to revolutionise electronics industry. Be it a silent heart attack detector that detects the protein level of a patient or a posture-correcting chair that alerts the occupant...
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...
Foodborne diseases, commonly known as food poisoning, are a very common occurrence. According to the Centre for Disease Control and Prevention (CDC), roughly 48 million people in the USA get sick and about 3000 people die every year due...
It’s eight o’clock at night. Everyone has left for the day. Still, you see all the lights and electric appliances running in your office. Putting up signs like “last person to leave turns off the lights” is read and...
