Bosch Connected Devices and Solutions make a LoRaWAN Parking Lot Sensor that detects the presence of a car in a parking space. This device enables interesting applications for car parks, like tracking usage, displaying the exact number of available spaces to reduce time searching for a free space.
We sell the sensors online, here:
To use this:
- create a TTN application and register your devices using the TTN console
- in your application, choose "Payload Formats" from the navigation
- paste the decoder function into the textarea
The unit sends a few different payloads that are well documented. A startup packet is sent when the unit is first installed, or reboots. Status updates are sent every time a car is parked or driven away from a space. The decoder function handles all of these.
This code is MIT licenced, and it works fine in our testing. We don't claim it to be excellent, pull requests are encouraged!
