Some car park management would require certain maximum height / size of vehicle that they allow to go in. This will be especially applicable for basement parking area. The traditional way of doing this is to put a gantry barrier to prevent over-height car to go in. With this traditional way, the person in charge of the car park might not be notified as he might not be around the location; and as a result, the oversized vehicle might force an entry.
Picobox will help to provide better a solution for this application. Infrared sensors would be place on point of entry and upon any object detected by the sensor, a signal will be sent to Picobox that would then notify the person in charge via SMS as well as automatically turning on an external buzzer or beacon light. With this solution, no matter where the person in charge is located, he can still be notified and manage the situation accordingly.
