A photocell sensor for a boom barrier typically consists of two main components: a transmitter and a receiver. The transmitter emits a beam of light, usually infrared, towards the receiver. The receiver, positioned opposite to the transmitter, detects the presence or absence of the transmitted light beam. When an object, such as a vehicle, interrupts the light beam, the receiver detects the change and triggers the boom barrier to open or close accordingly.
The key advantage of using a photocell sensor in boom barriers is its non-contact nature. Unlike traditional sensors that rely on physical contact with the vehicle, photocell sensors operate by detecting light, eliminating the need for physical interaction. This non-contact method ensures that there is no damage to the vehicles or the barrier itself.
Photocell sensors offer several benefits in terms of reliability and accuracy. They can detect vehicles of varying sizes, from motorcycles to larger vehicles, without any adjustment. The sensors are also highly sensitive and capable of detecting even small objects that might come into the path of the barrier.
