Node.js module for Open Thermal Camera

Node.js module that communicates with the Open Thermal Camera (OTC) via serialport. OTC communications protocol uses COBS, for which we have used cobs Node.js module.

Installation

Module is available on npm

$ npm install otc

Examples

There are a few examples of how to use the module in /test-otc and /test-mlx MLX90640.js is used for parameter extraction and getting temperature from bytes. It is just a JS version of original MLX90640 library published by Melexis
