Inside, things are a little more complex. The Kube uses the NodeMCU development board, and a custom breakout that [bkpsu] designed to interface with the display and sensors. For temperature and humidity monitoring, the Kube is using the ever-popular DHT22, and [bkpsu] mentions that he has future plans for things like motion sensors and direct control of RGB LED strips. All the data collected by the Kube is piped into openHAB via MQTT.
On the very detailed Thingiverse page, [bkpsu] gives background information on his design goals for the project, tips for printing out a high-quality case, a parts list with Amazon links, and pinout information for getting it all wired up. The PCB is even available on OSH Park for those who want a Kube of their own.
There are a lot of environmental monitors in the running for this year’s Hackaday Prize. Whether they’re soil moisture sensors for gardens or ultraviolet sensors for the beach, the entrants for The Hackaday Prize seem to grasp the inevitable truth that you need information about the environment before doing anything about the environment.
But what about sharing that information? Wouldn’t it be handy if there were an online repository where you could look up environmental conditions of any location on the planet? That’s where [radu.motisan]’s Portable Environmental Monitor comes in. It’s a small, pocketable device that measures just about everything and uploads that data to the Internet.
[radu]’s latest project expands on the capabilities of the Global Radiation Monitoring Network with more sensors and portability. Inside the Environmental Monitor are enough sensors to look at Alpha, Beta and Gamma radiation, dust and toxic gas, and other types of pollution. With the addition of an ESP8266 WiFi module, this portable device can upload sensor readings to the Internet, greatly expanding [radu]’s uRADMonitor network.
The ‘Internet of Flowers’ is upon us thanks to an artist named [Adrian]. He has designed a project that not only monitors the growth of Poppy Flowers but also monitors the soil, air and surrounding activity.
The entire project is based on a Raspberry Pi mounted in a purpose-built enclosure made from laser cut birch plywood. The enclosure is mounted in a window of an adjacent building that has a view of the flower bed. An internally mounted camera was carefully aligned so its field of view was mostly of the plants and would limit taking photos of unknowing passersby. The camera takes a snap shot every 5 minutes, see the time lapse video below.
A box containing sensors is installed in the flower bed. The intent of this project was not to have the Raspberry Pi spit out hard factual data regarding soil moistness, temperature and ambient noise, but to instead take that data from the sensors and send out a story-like narrative that makes the communication feel more personal.

[Daniel Klien] sent me his thermd environmental monitoring project. It’s written in perl, but the cool part is the sheer number of supported devices. It’s pretty rare when a single developer is given test hardware so he can add support for it.
Sure, this isn’t a hardware hack, but temperature logging is one of those irritating problems of hardware hacking. I’ve got loads of uses for it – coffee roasting, house management, battery charging, monitoring for my EV motorcycle project.
