Outline: ESP8266, Lua, MQTT, & Temp/Humid/OLED Project

Wow! What a mouthful.

Here’s the objective:
Design and build a compact devise utilizing the components listed above (title) to develop an easy to construct, stand alone, sensor capable of detecting temperature and humidity, and having it display locally and remotely on like devices.

So what does this really mean?

I’m looking to design & build a circuit board that allows for a plug-in of a ESP8266 module (don’t know which one yet), plug-in of a OLED (display) module, and have it communicate over WiFi through a MQTT broker. Each module would subscribe to every other module’s information such that each module would display the temp and humidity of other locations within the network.

With the use of an “Internet” based broker, this network need not be local…in fact it could be world-wide. I know there are project out there like this, but I’m looking to develop the hardware assembly in a form that makes it easy for kids to build.

My goal is to take this start to finish, eith the selection of components, the drawing of the PCB, the making of the board (etching and drilling), the assembly of components, the programming of the module, and the development of the broker.

Package this up as a set of directions that kids can follow and make it a segment of “Explorer Series” of the T-Recs summer camp.

Looking for ideas and suggestions, so please feel free to comment.

Thanks all!


Learning More About ESP8266 , LUA, and MQTT

I got to attribute my sudden interest in the ESP8266 cheap WiFi module yo Peter Scargill’s work on putting together a really good blog. He mentions that a fellow is merging MQTT code with an easy to use interpretive language called LUA. I would love to see a Forth language formed for the ESP8266…how cool would that be?

For the MQTT/LUA thing you can visit I think the BIN file is ready to flash onto the ESP chip. I’m still waiting for my modules to arrive. Hopefully soon and then I can give a play-by-play about how to make stand alone devices….as I’m hoping to do with the kids in my camp this summer.
