The Electronic Car Park Guiding System is the perfect solution to ease traffic congestion for commercial buildings. With this system, motorists will find parking spaces with ease even if it is the last one. This will automatically increase customer satisfaction and patronage, increasing car park income. This system can tell you exactly how many spaces are available in your car park accurately and provide useful information and data via a software system. With the Car Park Guiding System, each parking bay is monitored with an ultrasonic sensor. The information on these sensors are then sent back to a central control unit for processing. The processor will then provide information to numerous active signages providing real time information to the customer. Data will be recorded on the occupancy and frequency accurate to each parking lot providing valuable information for the management.
