Just got the dht22 temperature and humidity sensor working with the dev board for Texas Instrument’s new, <$10 wifi + microcontroller. Still early, but it’s looking like we’re gonna have quite power-efficient, meshable wifi on growerbot v2. Much more soon!
After *many* attempts, I’ve gotten the soil probe enclosure for growerbot v2 to where it’s 3d printable! There are 3 parts: the enclosure body, a press-fit lid that holds the solar panel, and the tip of the soil probe. i’ve successfully printed on both an ultimaker in pla and a lulzbot in abs; the abs should stand up to repeated use better. Here’s stls’s for you to print your own!
