[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 recognized. There’s no electrical energy accessible there both — whichever monitoring answer 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 certain 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 every thing as he goes – in truth, there’s entire seven blog posts on this venture, protecting the already accomplished software, PCB and 3D design levels of this venture.
These worklogs have loads of explanations and photos, and [Renzo] exhibits a wide range of totally different manufacturing strategies and tips for novices alongside the best way. The final weblog publish on 3D designing and printing the sensor enclosure was lately launched, and that possible means we’ll quickly see a publish about this method being put in and examined!
[Renzo] has been within the “intricately documented worklogs” enterprise for some time. We’ve coated his 3D printed PCB mill and DIY soldermask course of earlier than, and lately he was seen including an online interface to a 3D printer lacking one. As for LoRa, there’s loads of sensors you possibly can construct – be it mailbox sensors, burglar alarms, or handheld messengers; and now you’ve gotten yet one more venture to attract inspiration and data from. [Renzo] has beforehand accomplished a LoRa tutorial to get you began, and we’ve made one about LoRaWAN!
