I am looking for wireless vehicle sensors that could be laid out on the ground to detect if a parking spot is occupied or not.
I am looking for sensors that can integrate with any of the IoT backends i.e. major public cloud platforms, are reliable and of course economical so that we can scale the solution.Can someone recommend any vendor products that fit the bill ?
The use case is to implement a simple parking counter/display based on the parking availability from the parking /vehicle sensors.
The connectivity type could be cellular3G/4G or LoraWAN as long as it is economical.
