Labeled positions inside car counter area
Nwave’s platform supports hybrid solutions, enabling the integration of per-space parking sensors and car-counting sensors within a single parking facility.
This setup is particularly useful when monitoring the occupancy of specific spaces, such as EV-charging spots, within a broader parking area equipped with vehicle counters. For example, it allows real-time tracking of available EV-charging spaces within a larger facility.
This document outlines the setup process for an area managed by a vehicle counting system that includes four EV-charging spaces.
As shown, the parking facility has two entry points: one for entry and one for exit. Each entrance should be equipped with sensors running “Car Counter” (CC) firmware.
The four EV-charging spaces should use sensors with “Per Space” (PS) firmware installed.
All sensors can be registered under the same project, zone, and group.
For the sensors to function correctly, label each position as follows:
Entry sensor position - label IN
Exist sensor position - label out
EV sensor positions - label EV
Given that the parking area has a total of 20 spaces, set the zone capacity to 20 using the following instructions: https://nwaveio.atlassian.net/wiki/spaces/ND/pages/3018686469/Car+Counters+Getting+Started#Capacity-configuration
You can read more about the sensor positioning in these documents:
Once sensors are positioned and labeled, analytics, car counting, and real-time parking systems will begin processing data.
Now you can see full parking occupancy on the Analytics Car-Counters page.
Please note that per-space and car-counting systems are separate, and each requires data from distinct APIs. For full parking occupancy, use the following request to the car counters analytics API:
curl --request GET 'https://api.nwave.io/analytics/v1/car_counters/realtime/occupancy_summary?group_by=group&zone_id=123' --header 'x-Auth-Token: XXXXXXXXXXXX'
To retrieve occupancy data exclusively for EV spaces, use the per-space analytics API:
curl --request GET 'https://api.nwave.io/analytics/v1/realtime/occupancy_summary?zone_id=123&labels=EV&group_by=zone' --header 'x-Auth-Token: XXXXXXXXXXXX'
However, if you are using GraphQL API v2, you can obtain occupancy data for both CC and PS sensors using a single API.
