nrf9160-aqi

This repo contains all the source code for our bachelor thesis called:

"Prototype of a cloud-connected monitoring system for EAQI, based on the nRF9160 SiP with an energy harvesting system"

We are 4 students (now through) studying Electronics Enginering (FTHINGEL) at NTNU in Trondheim, Norway. This thesis has been developed in collaboration with Nordic Semiconductor, where we were tasked with building a prototype of a weather station that was based on their chip, nRF9160, with an energy harvesting system. This system should also be able to send data to a cloud service.

This repo contains all of the source code from the thesis, including the sensor drivers for the air quality sensors, based on the nRF environment, and the Leshan/database code that we used for cloud services.

Use

Building the code for Thingy:91

west build -b thingy91_nrf9160ns -p -- -DOVERLAY_CONFIG=overlay-queue.conf

Building the code for the nRF9160DK

west build -b nrf9160dk_nrf9160ns -p -- -DOVERLAY_CONFIG=overlay-queue.conf

** (Note that for the nRF9160DK, Kconfig settings CONFIG_LWM2M_IPSO_TEMP_SENSOR, CONFIG_LWM2M_IPSO_HUMIDITY_SENSOR and CONFIG_LWM2M_IPSO_CONC_SENSOR needs to turned off) **
