Developers, makers and hobbyists interested in data logging applications may be interested in a new Feather and CircuitPython data logging guide created by Adafruit and written by Kattni Rembor. The project combines the Feather M0 Express, the Adalogger FeatherWing with real time clock and SD Card, and the AM2320 digital temperature and humidity sensor.
The project allows you to create a small battery-powered sensor that is capable of gathering temperature and humidity data. Using CircuitPython Code to graph your data, Kattni explains a little more “We use the short male and female Feather headers to keep the project slim. We add in a lithium ion polymer battery so the project can go anywhere. We’ll use CircuitPython to write up a program to gather information from each of the sensors and save it to a log file on the SD card. Once we have some data to work with, we’ll import it into a spreadsheet and turn it into an awesome graph!”
