Hi here, we have been building and using about 20 dust sensors and now we are looking into a (few) noise sensors, based upon the variant - NODEMCU and DNMS separated -
Are there at this moment complete noise kits available, that is with pcb’s , other parts etc or haven’t we arrived at that point in time yet and will we still have to shop ourselves ?
Deedee, thankyou for this info. It’s the first time I have to order pcb’s by sending Gerber files to a manufacturer; which was the reason for asking.
I’m interested to know if the sensors you build were indeed based upon the Esp8266 or was it Esp32 ?
Could you perhaps point me to info on the difference of versions V1.2 and V1.4 of the DNMS pcb ?
Hi, I don’t know the difference, but I can ask for you. I am in touch with Helmut Bitter, the developer of this sensor. He is very active. I saw that there is also a version 1.6 on his github hbitter (Helmut Bitter) · GitHub.
The prints I have ordered are version 1.2. These are with nodemcu version 3.0, but version 2.0 works as well.
The Nodemcu is a board with an esp8266.
You also need a teensy 4.0.
If create an account and login into github you can ask Helmut himself.
I am not sure if it’s performance is identical to the DNMS. There was a related discussion going on about a couple of years ago, but I am not sure about the current status. I wonder if @bertrik would like to chime in.
As far as I know there is not. My sensor is hanging about 4 m high, but that’s because I live on the second floor.
If you register your sensor at the sensor community you have to register the placement height and position (garden, street) as well.
I am thinking about putting a LoRa noise sensor on the roof as well. That’s about 16 m.
I have already built two LoRa operated multigeigers. LoRa was quite complicated to learn as the manual was made for an older LoRa version. I have written a new manual on how to configure a LoRa multigeiger.
Hi, Deedee, I found the PCB differences in the README.md from hbitter and they provide enhancements and small options to the print. Concerning your 2 sensors on the picture you sent, what were your main reasons for creating the new shape you use ?? Temperature perhaps ?
