Each sensor has a finite sensing range, determined by the___________ floor of the sensor

The sensing range of a sensor is determined by various factors, one of which is the noise floor of the sensor. Here's why:

Noise Floor: The noise floor represents the minimum detectable signal level by a sensor in the presence of background noise. It is a measure of the sensor's sensitivity and ability to distinguish a weak signal from noise. Sensors are designed to operate above their noise floor to ensure accurate and reliable sensing.

Sensing Range: The sensing range of a sensor is typically defined as the maximum distance at which the sensor can reliably detect a signal above its noise floor. In other words, if the signal strength falls below the noise floor, it becomes indistinguishable from the background noise, and the sensor cannot reliably detect it.

Finite Sensing Range: Since the noise floor sets a lower limit on the detectable signal strength, it effectively limits the sensing range of the sensor. Beyond a certain distance from the sensor, the signal strength diminishes, and it may eventually fall below the noise floor, making it impossible for the sensor to detect events or objects beyond that range.
