+# lora-gps senseBox
+
+This is a GPS tracked senseBox measuring particulate matter concentrations,
+transmitting its data via LoRaWAN through [TheThingsNetwork] to [openSenseMap].
+
+[TheThingsNetwork]: thethingsnetwork.org
+[openSenseMap]: opensensemap.org
+
+It's based on
+- Arduino Mega (Arduino Uno should work to, just use SoftwareSerial for the SDS011)
+- Dragino LoRa- & GPS-Shield
+- SD-card reader (I used the one on the senseBox-Shield. Any other one should work as well, change the `SD_PIN` in `config.h`)
+- Novafit SDS011 particulate matter sensor
+- HDC1008 temp- & humidity sensor
+
+For mobile power supply I used an Adafruit LiPo charger + 5.6Ah LiPo.
+
+## Sketch setup & opsensensemap integration
+
+- Register a device under <https://console.thethingsnetwork.org>
+  - register a new application first
+  - register a new device
+  - note down the following values: Device ID, Application ID, Device EUI, App EUI, App Session Key
+  - add the HTTP Integration to your application and point it to POST to `https://ttn.opensensemap.org/v1.1`
+    (no authentication headers are required)
+- Register a senseBox at <https://opensensemap.org/register> (or use the script `register-osem.sh`!)
+  - select `mobile` for exposure
+  - select the location where you plan the first deployment
+  - select the model `Luftdaten with SDS011 & DHT22`
+  - enable TheThingsNetwork Integration, and insert your Device ID and AppId, choose profile `lora-serialization`.
+    Insert the following into Decode Options:
+    ```json
+    [{"decoder":"latLng"},{"decoder":"temperature","sensor_title":"Temperatur"},{"decoder":"humidity","sensor_title":"rel. Luftfeuchte"},{"decoder":"temperature","sensor_title":"PM2.5"},{"decoder":"temperature","sensor_title":"PM10"}]
+    ```
+
+- Insert the EUIs & App Session Key you received from TTN in `config.h`
+
+## Hardware Setup
+- Flash the sketch using Arduino IDE
+- Stack the senseBox Shield onto the Arduino, then stack the Dragino shield on top.
+- Remove the `GPS_TX` and `GPS_RX` jumpers on the Dragino Shield, and wire these
+  pins instead to the Arduinos `RX3` and `TX3` pins.
+- Wire the SDS011: RX & TX go to `RX2` and `TX2` on the Arduino, GND to GND, 5V to 5V ;)
+- Connect the LiPo to the LiPo-Charger, and connect the USB Output to the Arduino
+- Done!
