Introduction

This board is a remote thermocouple monitor. It is pretty much a direct implementation of App Note SBAA189 from TI. It uses a TI ADS1118 to read the thermocouple and a Particle Photon to connect via WiFi to the Internet.

The first intended use was to monitor furnances in a materials science laboratory, providing a way for researchers to check on the health of the furnance from home without having to physically go to the lab.

Getting Started

The fastest way to get started is to run the Particle app on your phone to claim the Photon, then flash the example app through the Web IDE. Detailed step-by-step instructions are located here. The example app updates the temperature to the SparkFun Data stream and the Particle cloud once every five minutes or so.

You can find the firmware libraries on github for the ADS1118 and for thermocouples.

Questions

How big is the Remote Thermal Monitor PCB?

It measures 48.3 × 52.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Remote Thermal Monitor use?

41 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Remote Thermal Monitor KiCad files?

From the ReclaimerLabs/Remote-Thermal-Monitor repository on GitHub, at the commit this page was made from: the board is electrical/Remote Thermal Monitor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Remote Thermal Monitor design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
