The goal of this project is to serve sensor data using a raspberry pi that include sensors:
- BME280 - including data for Humidity, Temperature, Barometric Pressus
- IMX90614 - non-contact infrared thermometer, used to determine the temperature of the sky to detect the presence of clouds. As the sky becomes more clear, the sky temperature is much colder. Comparing the IR temperature with the ambient temperature gives an indication of cloud cover.
- SQM-LE, or a Home-built SQM-LE - used to measure the sky brightness in units of magnitudes per square arcseconds.
These data can be pushed to a mosquitto MQTT broker, or served via a rest api.
On a clean raspberry pi lite install, run the setup script. It installs python, and python libraries, registers the service and enables it on reboots
pi@astro-sensors:~/rpi-astro-sensors $ ./setup.sh
Edit the main.py file to point to your MQTT broker.
Run the service with
pi@astro-sensors:~/rpi-astro-sensors $ systemctl start astro-sensor.service
Stop the service with
pi@astro-sensors:~/rpi-astro-sensors $ systemctl stop astro-sensor.service
Restart the service with
pi@astro-sensors:~/rpi-astro-sensors $ systemctl restart astro-sensor.service
