Environment Server

This new version of the Env server uses a Nano, DHT-22 sensors, Air Pressure Sensor, and a MAX485 for communication.   Note that I had to switch power on and off to the Air Pressure Sensor, it's readings increase when it heats up.   The sensor ohms at 5K, or 1 Ma at 5V, so switching it on and off is trivial, it does, however, require at least 20 Ms to stabilize after turn on.

Original Nano Env Server with of it's DHT22 sensors.

The Nano plugged into one of the screw terminal breakout boards mounted on my test board.   Note: the Env Nano is getting it's power from the NanoEth Nano..   Since I have a number of Nanos, I put a sticker on each stating the program loaded into it.   Interesting power distribution device.

Testing softwareserial in 2 servers.   Using a simple relay Nano (in port A out port B), I'm testing communication to Env server via Valve8 controller.   Rly Nano is top right, Env server is bottom right, and V4 is left.   You can see the V4 limit switches on the left.   Note USB cable into Rly, both the other servers are powered from Rly (USB)

Closer look at the V8 (4" slider valve controller).

Closer look at the Env server Nano mounted on a Nano expansion board and wooden base for the Nano Mount.   Note the ground and +5 volt distribution busses (lower center).

Closer look at the Gateway.

Closer look at the Env server nano.

This 5 port gigabit switch, on the south wall of the small shop bay, is connected to our 1Gb backbone (yellow CAT-5).

The Env server (environment server) temp install above the work bench.   I still have to mount the internal and external sensors.   The external sensor will be through the garage door that doesn't open an under the recess for the door.

From a different angle, note the V8 slide valve at the bottom of pic.   When I connect the Env server to the DustAutomation (DA) system, it'll be via the V8 controller which is nearby.

Housing for Env server.   Please see Nano Mount for more details.

After painting a distinctive color.

The Env server mounted in it's orange box.

Another angle.   Note how the cables fit into the mouseholes, its easy to remove the Nano from the box without unplugging any cables.   By the same token, its easy to plug in the cables before putting the Nano into it's box.
