Just found your channel, Oida! Nice work! I did my Bachelor's Thesis on that topic with OpenSprinkler open HW & SW but was running into some kind of buffer overflow (on the esp8266), when adding the libraries for INA and SHT31, as well as the MQTT publishing. I still think (as OS has an api) it might save you some time, if not directly, then maybe as template or inspiration. Furthermore, have you looked into Mi Flora Plant Care Sensor, or the Miyo Sensor S2? You could add a small solar panel to your soil humidity sensor (like miyo did), to make it autonomous. Finally, maybe you want to look into applying conformal coating to the edges of the pcb, if they haven't already. Otherwise, moisture can slowly seep into the pcb from the raw cut fiberglass edge. I've had limited success with nail polish, I'd use epoxy or the like if I'd do it again.
Thank you so much, glad you like my project! I was already familiar with the Mi Flora sensor, but the Miyo sensor is new to me - thanks for the tip. I had read about coating the PCB edges before, and I plan to cover that in the #4 part of the series, when buiolding a prototype. I was thinking of using conformal coating (422C) instead of epoxy since it's more liquid and might seal the fiberglass better through capillary action. What do you think about that?
@@creativemakerat I'm looking forward to that. - Sounds like fun! You might already know it: For solar, Andreas Spiess's (sensorslot) superpower project Discord has a link to a Gdrive with cool Power Systems BOMs & schematics, including one for solar with the LTC4162 charging ic. MPPT might not be necessary.
I don’t have much long-term experience yet, except for the sensor in my houseplant. After six months, it still looks just like it did at the start. I’m currently setting up a test setup for my garden - more details will be shared in the fourth part of the series. For this test, now I’ve also coated the sensors on the side with protective lacquer to prevent the fiberglass from absorbing water. We’ll see over the next year how well the sensors hold up.
Thanks for the part 2 👍
looking forward to the next part, I like that you have replaced my searching time to viewing time, thanks for the work
Thank you for the feedback. I'm glad the content was helpful to you.
Can't wait to see the next parts! You do an excellent job at explaining the concepts and it's easy to follow!👏
Thank you for the kind feedback. I really appreciate it! 😊

Damn, again a cliffhanger… 😄
Good news, the next epsiode is coming tomorrow evening!
@@creativemakerat Literally hanging onto the edge of my seat here :3
Great video just subscribed!
What about long time running ? Wondering about oxidation and UV.
