[Renzo Mischianti]’s good friend has to maintain a water tank topped up. Downside is, the tank itself is 1.5 km away, so its water degree isn’t sometimes identified. There’s no electrical energy obtainable there both — whichever monitoring resolution is for use, it needs to be low-power and self-sufficient. To assist with that, [Renzo] is working on a self-contained automation project, with a solar-powered sensor that communicates over LoRa, and a controller that receives the water degree readings and powers the water pump when wanted.

[Renzo] makes positive to prototype each half utilizing shields and modules earlier than committing to a design, and has already wrote and examined code for each the sensor and the controller, in addition to created the PCBs. He’s additionally ensuring to doc all the things as he goes – the truth is, there’s entire seven blog posts on this challenge, masking the already accomplished software, PCB and 3D design phases of this challenge.

These worklogs have loads of explanations and footage, and [Renzo] reveals quite a lot of totally different manufacturing strategies and tips for learners alongside the best way. The final weblog submit on 3D designing and printing the sensor enclosure was just lately launched, and that seemingly means we’ll quickly see a submit about this method being put in and examined!

[Renzo] has been within the “intricately documented worklogs” enterprise for some time. We’ve lined his 3D printed PCB mill and DIY soldermask course of earlier than, and just lately he was seen including an internet interface to a 3D printer lacking one. As for LoRa, there’s loads of sensors you may construct – be it mailbox sensors, burglar alarms, or handheld messengers; and now you might have another challenge to attract inspiration and data from. [Renzo] has beforehand completed a LoRa tutorial to get you began, and we’ve made one about LoRaWAN!
