# 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!
