How to get weather telemetry with a BME280 on your Meshtastic Heltec V3. 

And someone who explains in mostly English..thanks!!

Straightforward easy to follow explanation. Thank you.

Thank you for the video, just ordered one I'm going to give this a go, once we have the UK covered imagine harvisting that data to a database would be one amazing weather app!!

Great video and I love the format; short and sweet to the point.👍

This is great, I wonder what other applications tying sensors into the mesh could have. If air quality monitors could be used in place of barometers then I can imagine this being used by grassroots groups to deploy area-wide pollution monitoring across a town. Moisture sensors could make an off-grid early warning system for a flood-prone community. There's so much potential.

I have used it to measure the temp of my beehives so useful for some tasks.

Awesome video👍 and another 100% essential purchase😆

Twisting wires only works IF it's a balanced signal. This doesn't appear to be.

I would pull the twisted pair from a cat 5 cable

Fantastic,,,

Nice vid! Can you give us a breakdown of your handheld 3D printed case. I know what it's modeled after, just not with the window for the heltec and such. Possibly post the STL from the model? Thanks and keep up the great information and range testing!!

There are also pliers with a small handle on the base you can pull out - this will spin around the wires while grabbed into the jaws As for twisting helping - apparently yes! I was going to debate that these aren't differential signals but apparently it doesn't matter. These circuits still benefit from using twists to make the noise common mode over Signal and Ground just the same as Signal+ / Signal-

Question - you showed the BME280 that requires 5V for power. However, the Heltec v3 is powered by 3.3v (max 4.1v). Is there any loss of accuracy since the BME280 isn’t running at the 5V it’s expecting?

what meshtastic firmware are you using to use pins 41 and 42? or how did you configure the pins to work?

Your link is for the 5v board, but these devices have a logic level of 3.3v right? It would be unwise to overload them with 5v, they may not all tolerate the overvoltage. But besides that absolutely great video thank you! :-D

Is that weather data showing conditions inside the case or outside the case? I couldn't tell from the view.

Any ideas on how to connect a buzzer that will activate as soon as the temperature reaches a set value like a temperature alarm?

Which case is that buddy? Also, nobody mentions which module it is, 3.3V or the 5V version sorry to have to ask.
