How do you connect the DHT22 to the board?
I see in the photo that it has male headers soldered to it.
Wouldn't it be a beter idea to put the DHT22 directly on the board, next to the SDS011 connector or opposite side in the area of the SDS011 input?
Experience learned that the wired connection between DHT22 sensor is a weak point because of the thin leads of the DHT22 sensor.
Having it to close to the NodeMcu or WeMos is also a problem because it radiates extra heat and can influence the data.
For our LoraWan version we put the DHT22 underneath the NodeMcu. Not our best idea ;-)
In June we're going to deploy an extra 100 sensors in Brussel (influencair.be), It would be cool to have a pcb like this.
