Sensors
What is sensor?
A sensor is a device that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena. The output is generally a signal that is converted to human-readable display at the sensor location or transmitted electronically over a network for reading or further processing.
What are the Different Types of Sensors?
In today’s world, you will be able to find sensors that are able to detect a number of different things. The following are some of the most common sensor types out there and a bit about each of them.Understanding more about the different types of sensors can help you determine which ones you might need to have for your own applications.
History of Sensors
Sensors have been around for quite some time in various forms. The first thermostat came to market in 1883, and many consider this the first modern, man made sensor. Infrared sensors have been around since the late 1940's, even though they’ve really only entered the popular nomenclature over the past few years. Motion detectors have been in use for a number of years
