This repository is Arduinio code (lib 2.5.1 based) to read PMS7003 data and relay it to a server, configurable over-the-air via WiFi Manager.

Features:

• Uses default serial port pins for debug/code load and swap pins for pms7003(no ESP8266 serial boot garbage)
• Periodic Reporting (10 minutes) of PM 1.0, PM2.5, and PM 10.0 data.
• Deep Sleep mode for 8266 and sleep mode for pms7003.
• Initial configuration of website/server destination via PMS_7003 WiFi Access Point.
• Allows over the air updates. Configure post response to send "update" to initiate.

Known Issues:

• WiFiManager.cpp needs patch to compile - see issues in that library.
• Access Point password protect didn't seem to work.
• Server port is hard coded - adjust as needed.
• Had one instance of ESP8266 locking up during thunderstorm. No water on board but wondering about EMF from lightning.

Project Construction:

• I just used point-to-point wiring. PMS7003 adapter board is recommended.
• Upside down blue electrical box from Home Depot seems to shield OK from rain. Recommend leave cutouts in. Oops, too late for me.
• Fiberglass mesh was added after spider added web inside unit which corrupted readings. However, spider mites are smaller than the mesh size so will block only larger insects.
