The AM2320 is a fantastic little sensor that gathers temperature and humidity data. You can print it to the serial console to see the information live! But wouldn't it be great if you could gather that data and save it? You can! The Adalogger FeatherWing is a board with a real time clock and an SD card slot. Combine this with the AM2320, and we can save all that lovely data to the SD card and do whatever we like with it!

This project combines the Feather M0 Express, the Adalogger FeatherWing with Real Time Clock and SD Card, and the AM2320 Digital Temperature and Humidity Sensor. 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!

Things You'll Need

Here are the items you'll need.

Handy To Have

• Double sided tape - This will allow you to attach the battery to the bottom of the project. You can use any kind of double sided foam tape for this. We used adhesive hook and loop fasteners to allow for the battery to be easily removed if necessary. You could also wrap them all together with a cable tie. There are tons of options!
