I am very new in this comunity and have no experiences with IoT and Lora. But i want to install parking sensors with the TTN Gateway and the whole TTN Backend stuff for my master thesis.
Till now i activated and installed the gateway successfully. For another project I activated an temperature sensor and receive the temperature via the gateway, so it’s working. I could write the appEui and the appKey to the sensor via USB cable.
My problem is that the parking sensors havent got a USB Interface, so I cant write the keys on the sensors nor configure them. I ordered the parkins sensors from this page http://www.iotsens.com/sensors_en/smart-parking-sensor-road-surface/ and received them without any installation or configuration instruction. After research I found similar sensors (https://market.thingpark.com/iot-devices/parking-light-sensors/geomagnetic-vehicle-detector-surface-mount#) with a short documentation (https://drive.google.com/file/d/0B6TBYAxODZHHa2pFN0dMWWR6alE/view). The documentation says that the sensors are always sending 5 Bytes, but the gateway is receiving 18 Bytes?!
After activating a parking sensor it sends three times data and remains silent after that. It doesnt sent any join request to which I could reply. Following an example of the payload: “80 52 00 03 70 80 02 00 01 78 9D C8 A9 F2 99 BC 7C A8”.
I want to forward the payload to an application which will forward the data again to a HTTP-Server. Is this possible without a successful join?
Has anyone experience in working with parking sensors and lora or any idea I could get further?
Thanks in advance
