@alf none of the smaller sensor will do actual pm10. The intergration time would be way to long to actually measure actual pm10 sizes reliable. They all calculate it from the measured pm2.5 values.

Hi all,

i am currently using microchip RN2483 for several projects (in none lora mode). Mainly because it's range was way better during several tests (compared to the RFM95 chip sets). But i really like mysensors also, so i wanted to see if a driver could be written for the RN2483 could be written by somebody. I am a c# programmer by trade and the normal arduino stuff i can manage just fine, but creating a driver for mysensors / rn2483 would be a bigger task for me. So if anybody would like to take on this, payed, challenge then just drop me a message!

ok thanks! Then i will order the dragino board to test if it will work. I really like the samd series, so i will just test it and see what happens.

Hi all,

i finally wanted to take the deep dive and get started using mysensors. I have got a few Samd21 boards laying around here with the RFM95 on it (from another project). I used them as dev boards and they are the:

Sparkfun Pro RF

Now i know that almost all these samd21 dev boards don't have any EEPROM on them. I have read quite a bit of posts about this on this forum also. But i can't seem to find any info (or i am totally not reading it right) if mysensors will break during build because of this (or that is just doesn't have the ability to store the node id etc, and just keeps asking for a new one during startup). I now there is the option to use the flash as a "sort of" EEPROM. I know there are some disadvantages to this also, but during development that isn't a problem for me. The idea is to just create a custom pcb in the end so i can just add EEPROM to it. I could also order multiple Sensebender gateway boards, but i don't know what the delivery time is form china (and i have got the other ones laying around).

As for the gateway. I was thinking about a PI for now with the dragino lora board. Did anybody use that one already?

but will each sensor node make his own connection to TTN? Or will the sensors use lora modulation and will only the gateway (or controller) connect to TTN?

Sorry you are right. Is wasn’t reading the post correctly (must have been a little sleepy...)

@mfalkvidd but for none lora purposes a single channel gateway might be just fine. I am also new to my sensors but I have designed several sensors in the past using the microchip rn2483. But then not as a Lora node. They where outdoor temp and humidity sensor which you can stick into the ground. They communicated with a base station several kilometers away (roughly 4km).
We also tested the rfm95, but the performance of the rn2483 was quite a bit better.

That was before I found the my sensors project though. I am thinking about using mysensors now for a new project, but Indoor coverage is pretty important. Large building with loads of concrete and steel. So propably the rfm95 will be best for this also (I have no experience with the nrf5 series, so I don’t know how the coverage of that is).
