Analog sensors are devices that measure physical quantities and convert them into continuous electrical signals. These signals can represent various parameters such as temperature, light intensity, or pressure. Unlike digital sensors, which provide discrete values, analog sensors produce a range of values that correspond to the measured quantity, allowing for more nuanced data representation. Common examples of analog sensors include thermistors for temperature measurement and photodiodes for light detection. These sensors are widely used in applications like automotive systems, industrial automation, and environmental monitoring, where real-time data is essential for effective decision-making and control.
