Meshtatic Adding Telemetry Environment Sensors

Here we take a quite look at how you can add an Environment sensor to any meshtatic lora board which has an I2C bus.

Great Matt, they have made all this easy now in the latest firmware. I see it will also will do canned messages. Time to update my firmware.

And as my node is on the same local mesh as to Matt, I can vouch for the all environmental & motion detection messages 😂

Perfect explanation thanks very much, better than I could have done it. I use this feature it's great.

Hello, did you have to solder the terminal strips on the Heltec and the BME before connecting on the breadboard? The holes and spacing between them are tiny. I just thought I'll mount the boards on the terminal strips without soldering and added the wiring but I don't get environment data so probably the BME is not "seen".

Is it possible to send a signal back the other direction

[mtsdawson]

Great video, thanks! Question... what about soldering this sensor AND the GPS board to the Heltec. I'm using Pin 2 for the GPS, so no issues there... but I need a Ground. Can I solder both boards to the same Ground Pin 1?

Great stuff, I have those sensors. Thanks for sharing!

Hey, i have a small Problem with the t114. Im to dump to connect / Run a AHT20/BMP280 or BME/BMP280 Sensor with meshtastic (meshtastic flasher Version 2.5.15.79da236 Beta)

Im to dump ... Do you have the right Pins (original meshtastic config for sda scl) to connect the Sensor?
Greetings from Austria

It looks like you're putting 5 volts to the BME280(?). I was under the understanding that the I2C lines should be 3.3 volts. And if that sensor is anything like the SHT31's that I have here, the I/O voltage is the same as VCC... so 5 volts VCC means 5 volts I/O. What am I missing (as I try to get my Heltec V3 to recognize any of my SHT31 sensors...)?

Great video, going to add my BME20 now. 2 questions. Can I add more than one sensor/ module at the same time? I want to add GPS and BME20. And what are canned messages? Thanks.

[irreverend_]

I don't suppose the AHT10 can be made to work easily? I have a few of those kicking around already

[Vikingza]

Thanks Matt, do you know of any info for the following sensors that would work with Mesh Tastic?
1. Wind speed and direction
2. Vibration sensor (to monitor the vibration on a radio mast)

Can one run 2 i2c sensors on the same unit? I am asking as I would love to use meshtastic with a wind sensor (speed and direction) and BME280 Sensor to do weather reporting on an hour or 2 hour cycle.

[daveys]

I have one of those air quality sensors but only used it on Arduinos. I fancy doing something with telemetry, as I already have nodes set up.

[bladdesdfsdf]

Please can you make a video for the BME680?

[SpookieNZL]

So? Do I need to purchase 5v or the 3.3v version? I intend to use on Battery Power. But while using the USB-C to flash it etc it I have it wired up for Battery. Would the USB burn out the 3.3v version? Little confused. Thanks.

[milliondollarboner]

Thanks for the video, great stuff. Quick question, have you managed too get the sensor data out if the mesh into something like NodeRed? I'm trying to figure this bit out!
Thanks

[fshieldsii]

Great video.
Just a little note on I2C... it is pronounced "eye-squared-see", not "eye-two-squared".

[GDDX]

Thanks Matt, nice video as usual.
How about taking exactly the same hardware and showing how to connect it to the ThingsNetwork given that many people are likely to get disappointed with Meshtastic once the hype cycle is over? There is a german video that describes it but didnt find a good english version.

[IndependentNewsMedia]

Nice video, keep up the good work, God bless.

[AutieTortie]

Did you say "I2square bus"?! You mean I²C bus 😂😂😂😂
