[Renzo Mischianti]’s pal has to maintain a water tank topped up. Drawback is, the tank itself is 1.5 km away, so its water stage isn’t usually 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 stage 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 every thing as he goes – in reality, there’s entire seven blog posts on this mission, overlaying the already accomplished software, PCB and 3D design levels of this mission.

These worklogs have loads of explanations and photos, and [Renzo] reveals quite a lot of totally different manufacturing strategies and methods for rookies alongside the way in which. The final weblog publish on 3D designing and printing the sensor enclosure was just lately launched, and that doubtless 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 just lately he was seen including an internet 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 have got yet one more mission to attract inspiration and data from. [Renzo] has beforehand finished a LoRa tutorial to get you began, and we’ve made one about LoRaWAN!
