To improve operations, each sensor contains a passive RFID tag. All configurations are selected from the calibration app which interacts directly with the sensor via a RFID transceiver. The sensor ID is capable of being read even without sensor battery or when sensors are broken.
A commissioning app allows operators to follow a pre-configured route (i.e. an ordered sequence of parking bays) and to manually introduce the occupation status of each parking bay. The app stores all values. It periodically requires to validate the identity of the sensor which is being inspected. In case a sensor cannot be validated, the auditor probably did not follow the pre-configured route correctly and the data is discarded. The application automatically retrieves the real occupation information of the sensor from the system servers. This ensures agile and accurate inspections while also minimizing the likelihood of human errors.
