Vinduino Water-Smart Farming – Now With LoRa!

Our five rounds of Hackaday Prize 2018 challenges have just wrapped up, and we’re looking forward to see where the chips fall in the final ranking. While we’re waiting for the winners to be announced at Hackaday Superconference, it’s fun to take a look back at one of our past winners. Watch [Reinier van der Lee] give the latest updates on his Vinduino project (video also embedded after the break) to a Hackaday Los Angeles meetup earlier this year.

Vinduino started with [Reinier]’s desire to better understand what happens to irrigation water under the surface, measuring soil moisture at different depths. This knowledge informs more efficient use of irrigation water, as we’ve previously covered in more detail.¬†What [Reinier] has been focused on is improving usability of the system by networking the sensors wirelessly versus having to walk up and physically attach a reader unit.

His thought started the same as ours – put them on WiFi! But adding WiFi coverage across his entire vineyard was not going to be cost-effective. After experimenting with various communication schemes, he has settled on LoRa. Designed to trade raw bandwidth for long range with low power requirements, it is a perfect match for a network of soil moisture sensors.

In the video [Reinier] gives an overview of LoRa for those who might be unfamiliar. Followed by results of his experiments integrating LoRa functionality into Vinduino, and ending with a call to action for hackers to help grow the LoRa network. It sounds like he’s become quite the champion for the cause! He’s even giving a hands-on workshop at Supercon where you can build your own LoRa connected sensor. (Get tickets here.)

We’re always happy to see open-source hardware projects like Vinduino succeed, transitioning to a product that solve real world problems. We know there are even more promising ideas out there, which is why Hackaday’s sister company Tindie is funding a Project to Product program to help this year’s winners follow in Vinduino’s footsteps. We look forward to sharing more success stories yet to come.

Optimizing Crop Yield With IoT

For a recent hackathon, a group of strangers (now friends!) created Crop Squares — a system designed to optimize crop yield by better tracking weather and soil conditions.

The event was hosted in Madrid called Future Hacks Internet of Things Edition, with the goal to build disruptive IoT solutions to help change the world. In 54 hours.

The concept behind crop squares is to make a graphical user interface using Dizmo that clearly shows the status of your crops in a grid system. For the prototype they used an Arduino Pro Mini with moisture sensors in potted plants to detect moisture levels, while a Raspberry Pi also collected weather data for the area being watched. The Arduino used an ESP8266 WiFi module to transmit the data remotely. To demonstrate how the system could be used in an automated sense, they hooked up another Arduino (this time a Leonardo), to pour water once the moisture levels dropped below a certain threshold.

Crop Squares won the Best Pitch Award as well as the Best Integration of Dizmo — good job guys!

Speaking of moisture sensors — did you know you can build your own using some plaster of paris and nails?
