EarthPod

Code for the EarthPod environmental sensor pod.

Datalogging-Arduino

Hardware

The code in this folder is intended to be used in a sensor pod based on a Adafruit Feather M0 Adalogger. Connected sensors include:

Sensor	V1	V2
RTC	DS3231	DS3231
Gyroscope	FXAS21002C	FXAS21002C
Acclerometer/Magnetometer	FXOS8700	FXOS8700
Temperature/Humidity	si7021	SHT21
Air Pressure/Temperature	BME280	BMP280 or SPL06-007
Light Level	SI1145	BH1750
Wind Direction	TCS34725	N/A
Wind Speed	Handheld Anemometer	N/A

feather-sensor-logging-v1

Compatible with V1 only

This program will create a .csv file on the Adalogger's SD card that records the measurements captured by the sensors. This program is only compatible with the Adafruit Feather M0 Adalogger, and will not fit on the Adafruit Feather 32u4 Adalogger due to memory constraints.

feather-sensor-logging-v2.1

Compatible with V2 Only

This program will create a .csv file on the Adalogger's SD card that records the measurements captured by the sensors. This program is only compatible with the Adafruit Feather M0 Adalogger, and will not fit on the Adafruit Feather 32u4 Adalogger due to memory constraints.

feather-sensor-tests/SPL06-007

Test I2C communication for an SPL06-007 air pressure and temperature sensor.

feather-sensor-tests/anemometer

Test initialization and interrupts for a wind speed sensor from a handheld anemometer.

Datalogging-Python

Hardware

The code in this folder is intended to be used in a sensor pod based on a Raspberry Pi or Google Coral. The primary sensing hardware is the Coral Environmental Sensor Board, which provides ambient light, barometric pressure, humidity, and temperature measurements. This board is compatible with both the Google Coral and Raspberry Pi. Additional sensors can be connected to the Environmental Sensor Board through a series of Grove connectors.

enviro_logging.py

This program will create a .csv file that records the measurements captured by the sensors in the Environmental Sensor Board.

enviro_logging_wind.py

This program adds functionality for reading wind speed using the sensor from a handheld anemometer.

enviro_logging_wind_airflow.py

This program adds functionality for reading wind speed using a F662 Board Mount Airflow Sensor from Degree Controls.

MagnetRelease

MagnetRelease.ino

Arduino program for the twist-release magnet system used to deploy the pod.
