@naturalblaze - I’ve made a couple of the ones shown here, the DHT22 sensors were shown farther up in that same thread and come on a board with a capacitor and resistor. It is connected to 3V3, GND and D4 when looking at this diagram.
And the board itself is powered by a 5V wall plug.
@anthony_maragou - to clarify your comment about direct connectivity, are you saying you favor those because you don’t need to have wifi in a particular area which is required by the ESP8266 wifi style sensor? Thanks
