How To make an environmental Monitoring system with BeagleBone and Arduino. by chrwei via instructables

This is a project I’ve been working on for a while, and still have ways to go, but I have enough success right now that I can I share what I’ve got. This covers connecting a Beaglebone and an Arduino via TTL serial and I2C, using a parallel LCD with an Arduino, using a DHT-22 with Arduino, and using DS18B20 1-wire sensors with a BeagleBone in the next week or so.

I believe that all the instructions here will apply more or less as-is to a RaspberryPI or pcDuino or any other little computer that supports TTL serial and i2c, and 1-wire for the DS18B20. As I get some ArchReactor (the local hackerspace) members to try this on their devices, I’ll update here confirming what devices work and add any relevant information.

My end-goal is to use several temperature, humidity, and other sensors spread through my house, including outside, and control my heat and AC and whole house fan in order to optimize and balance comfort and energy use. The details of how that will work are yet to be nailed down, and I’m going to start with monitoring so I can see what kind of data I have to work with.

This instructable will explain how to get started with using an Arduino and Beaglebone and a couple sensors and a display.

Stuff you’ll need:
– BeagleBone
– Ardunio
– TFT LCD
– Sensors
– lots of jumper wires!

I’ve had a BeagleBone for a while, but a Black should work the same. For the Arduino you can prototype with an Uno or other standard arduino compatible, but I’m using a breadboard arduino, and I’ll eventually make a PCB for it, so that I can integrate it into as small a case as possible. For the LCD, I’ve chosen an 2.8″ TFT with touch screen. There are certainly easier to use LCDs out there, but this one is only $18, and I have enough IO’s to make this run in 8-bit mode. I’m starting with the DHT-22 temp and humidity sensor, and I’ll be adding DS18B20 temp sensors soon.

BeagleBone Adafruit Industries Unique fun DIY electronics and kitsEach Tuesday is BeagleBone Black Day here Adafruit! What is the BeagleBone? The BeagleBones are a line of affordable single-board Linux computers (SBCs) created by Texas Instruments. New to the Bone? Grab one of our Adafruit BeagleBone Black Starter Packs and check out our extensive resources available on the Adafruit Learning System including a guide to setting up the Adafruit BeagleBone IO Python Library. We have a number of Bone accessories including add-on shields (called “capes”) and USB devices to help you do even more with your SBC. Need a nice display to go along with your Bone? Check out our fine selection of HDMI displays, we’ve tested all of them with the Beagle Bone Black!


As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
