Abstract: A contactless gate position sensor includes an optical time-of-flight sensor positioned within a predetermined proximity of a gate for detecting a closed position of the gate and an open position of the gate. The optical time-of-flight sensor has a predetermined field of view. When a predetermined portion of the gate is within the predetermined field of view, a status of the gate is set to a closed status. When the predetermined portion of the gate is outside the predetermined field of view, the status of the gate is set to an open status. The status is detected by the optical time-of-flight sensor and transmitted using a data communication network.
