Sensor technology refers to the development and use of devices that can detect changes in their environment and convert those changes into measurable signals or data. Sensors can be used in a variety of applications, including environmental monitoring, medical diagnostics, industrial automation, and consumer electronics. These devices can detect various physical properties such as temperature, humidity, pressure, light, sound, motion, and chemical composition. Sensor technology plays a crucial role in enabling the collection of data for analysis and decision-making in a wide range of industries and research fields. Advances in sensor technology have led to the development of smaller, more accurate, and more cost-effective sensors that are revolutionizing the way we interact with our surroundings.
