Abstract
An object counting device adjusts a signal to account for noise to improve object counting accuracy. A controller receives an electromagnetic radiation (e.g., light) intensity signal from radiation detectors and determines that its value is within a voltage threshold, thereby indicating that no object is passing through the radiation. The controller determines a derivative of the signal and that the derivative is less than a derivative threshold level for at least a predefined time. The controller then updates a base noise floor value to be the value of the radiation intensity signal to account for particles within a path of the electromagnetic radiation to improve an object counting accuracy. In some embodiments, the processor can scale the received radiation intensity signal in accordance with the updated base noise floor value.
