Have you tried BME280 sensors? It seems for me that single BME280 sensor can substitute this sensors list:
DS18B20 (temperature sensor)
DHT11 (humidity sensor)
Si7021 (humidity sensor)
BMP180 (pressure sensor)

No, I haven't.

BMP180 (pressure sensor)Of course it is possible. I use the most popular types of sensors in the community, for which there are many ready-made examples. Also, everyone can solder just necessary sensors for him to make its own device.
But despite this, I am ready to discuss a set of sensors in my "Multisensor"..... and I don't have ordered pcb's , it means that something can be changed
-
Is it possibe to add any additional sensors to the build, like PIR?
-
I have received the pcbs from PCBWAY. Quality as always on top + a small price (10$ - 10pcs). I am going to solder two versions with different radios ASAP. To be continued...
-
The first MDMSensor board is assembled (NRF24 version). Now I'm going to test it and make enclosure.
-
Very cool. What kind of connector are you using to connect to the programming pads?
-
@TD22057, This is Industrial Card Edge Slot Socket Connector
I use my own handmade an adapter for programming.
It has a lot wires, instead this i made the MDMSAccessory "Programming" few days ago.
-
Possible to add also other battery holder like CR123 or CR2450 to the board?
-
@MiKa Yes, i think it is possible. I already have some improvments for this device, but i have no free time to do this, because i am working on MDMSNode "Power" now.

Hi @kalina. Sorry for rebumping this topic with an unrelated concern.
I am interested in the enclosures you've made for this design and for your gateway.
I have finished a design of my own and now I want to design the enclosure, but I have found that is very expensive to have a custom case built for this prototypes boards, specially when dealing with low volumes.How do you deal with this issue? Have you found a cheap plastic case manufacturer?
Thanks!

I look for an enclosure on the Aliexpress site, but all these enclosures not ready for using, they require machining on CNC machines.
-
I have made the firtst device with enclosure already...
-
Is that 3d printed or did you do some injection moulding?
-
@hek I hope he did some cnc work on it
-
@gohan Yes, you are right, this is done by cnc router.
