Planet Arduino

Home monitoring is a big part of home automation, but it’s often overshadowed. Our attention tends to get hijacked by cool projects that perform physical actions. Whether it’s turning the lights on, changing their color, running a robot vacuum cleaner, pulling on the blinds or watering the garden. All these actions are very cool and very visible. Which makes it easy to ignore the background tasks that are the backbone of great home automation.

YouTuber and robotics maker RootSaid has been giving this a lot of thought. He’s put together an excellent tutorial on creating a self contained, real-time home monitoring module. It’s built around the excellent Nano RP2040 Connect, and sends everything to Arduino Cloud.

Home Monitoring for You, and Your Family

His objective was to create a compact bundle of sensors to keep an eye on various conditions around the home. This battery powered system can then be positioned anywhere, and monitored from Arduino Cloud. His idea is to install the module in an elderly relative’s home. That way, he can keep an eye on their environment from anywhere.

Of course, this doesn’t have to be used purely as a care system. That’s a great application for his environment monitoring platform, but it’s just as useful for your own home automation system. Too often, sensors (temperature, for example) are physically connected to other automation devices, like Wi-Fi mains switches. But chances are you want to know the temperature over by your sofa. Not down the back of the TV cabinet.

RootSaid to the rescue.

A Compact Home Automation Sensor Module

Let’s take a look at the sensors bundled into this compact package.

He’s got an LDR in there to monitor the light levels. This is perfect for bigger home automation projects, as it can trigger lights all around the house. Even outdoor lighting, if you wanted.

There’s a Bosch BME280 to keep an eye on the environment. This is becoming a popular device among the home automation crowd. It’s small, very low power, cheap, accurate, and gives you temperature, humidity and air pressure data.

Finally we have a gas sensor, which is a really interesting addition. Especially as part of his original brief for monitoring an elderly relative’s environment. It keeps a check on air quality, but being able to get alerts for gas leaks or rising carbon monoxide levels could be life saving.

Home Monitoring in Arduino Cloud, for Free

Finally he takes you through the Arduino Cloud set up, including a monitoring dashboard. Which is more good news, since all this is running from a single Nano RP2040 Connect. That means you’re only adding one Thing (with five variables), so the free tier is a practical option. If you want to begin comparing the data the module collects over time, you can then easily bump up to a subscription for longer data retention options.

Because he’s collecting data through Arduino Cloud, he’s automatically got smartphone access to it, as well. Or, if he wanted to share the data with members of the family or household, it only takes a click.

Although RootSaid is running his module from a 9V battery, there’s nothing to stop you using other power sources. The Nano RP2040 Connect will accept all kinds of voltage inputs. From USB to 12v PSUs, your power options are wide open here.

This is a project that no home automation enthusiast should overlook. It’s small, simple and very easy to build. But it’s also the gateway to creating a great home automation system. If you’re only just getting started, this is the project to begin with. It’s the tiny module where all the important data comes from to make your home truly autonomous. RootSaid’s excellent tutorial also makes it easy to see how you can expand on the project in lots of ways.

The Arduino Pro lineup continues to grow with the introduction of the new Arduino Edge Control. This is a remote monitoring and control solution optimized for outdoor environments. Easy deployment makes it suitable for smart agriculture, precision farming, and other intelligent control applications in remote locations.

Featuring built-in Bluetooth, Arduino MKR boards can expand connectivity with 2G/3G/CatM1/NB-IoT modems, LoRa®, Sigfox and WiFi. With solar power capabilities you can place it anywhere while leveraging AI on the edge. Once installed in the field, it can then be managed remotely using Arduino IoT Cloud (or other services). 

Real-Time Monitoring with Edge Control Sensors

You can also connect sensors, provide real-time monitoring, and drive actuators — commonly used in agriculture — thereby reducing production-related risks.

Particularly aimed at smart agriculture, the sensors can collect real-time data. Weather conditions, soil quality, crop growth and any other data you need. Once sent to Arduino IoT Cloud, the data value chain becomes valuable analytics that support business processes at various levels. For example, crop yield, equipment efficiency, staff performance and so forth. The Edge Control can improve crop quality, reduce effort and minimize error by automating processes like irrigation, fertilization or pest control.

Remote Access and Maintenance

With its robust design, the Edge Control is a fitting solution for applications in any outdoor setting. For example, using it on construction sites or in real estate to automate access control. Similarly, swimming pool maintenance and cleaning companies could monitor and control the condition of pool water from remote locations. As usual, we expect the Arduino community to come up with countless ingenious ways to implement this new technology.

To learn more about how you can use the Edge Control, check out how to get started.

The Edge Control is now available for €169/US$199 on the Arduino Store.

[Amitabh] was frustrated by the lack of options for controlling air pressure in soft robotics. The most promising initiative, Pneuduino, seemed to be this close to a Shenzhen production run, but the creators have gone radio silent. Faced with only expensive alternatives, he decided to take one for Team Hacker and created Programmable Air, a modular system for inflatable and vacuum-based robotics.

The idea is to build the cheapest, most hacker-friendly system he can by evaluating and experimenting with all sorts of off-the-shelf pumps, sensors, and valves. From the looks of it, he’s pretty much got it dialed in. Programmable Air is based around $9 medical-grade booster pumps that are as good at making vacuums as they are at providing pressurization. The main board has two pumps, and it looks like one is set to vacuum and the other to spew air. There’s an Arduino Nano to drive them, and a momentary to control the air flow.

Programmable Air can support up to 12 valves through daughter boards that connect via right-angle header. In the future, [Amitabh] may swap these out for magnetic connections or something else that can withstand repeated use.

Blow past the break to watch Programmable Air do pick and place, control a soft gripper, and inflate a balloon. The balloon’s pressurization behavior has made [Amitabh] reconsider adding a flow meter, but so far he hasn’t found a reasonable cost per unit. Can you recommend a small flow meter that won’t break the bank? Let us know in the comments.

During Fab10- Fab Festival in Barcelona I met Jin Shihui who introduced me to CandyProject, a research project exploring the process of spraying natural fiber to create a non-woven textile that can be used to produce anything from building components to ornamental artifacts.

By means of air pressure we separate the fibers from a roving allowing them to self-organize and reassemble due to the surface tension caused by a fine mist of adhesive. This creates a controlled fibrous aggregation producing an emergent morphospace encompassing the initial substructure.

The robot Jin is holding in her hands in the picture above uses air pressure to separate fibers into individual strands. While the fibers are still separated they are embedded with an adhesive spray and all parameters are controlled within the robot  with an Arduino Uno:

Designing an end effector for the robot to precisely spray the fibers allowed us to predefine the spraying protocol of any object, while also modifying the material properties at each of its parts. Varying degrees of material density, thickness, and rigidity could be achieved by simply adjusting certain parameters in the spraying process while always insuring repeatability and precision. Controlling these properties, coupled with the environmental and thermal nature of the fibers used, opens up a wide range of possible applications ranging from optimized building envelopes to furniture and custom made fashion. We want to share details of our project  so everyone can  build your own spraying tool and develop your usage with this technic.

Take a look at the video below showing the whole amazing process from growing to spraying the fibers:
