Arduino Temperature Sensor Project

Description:

I'm working on an IOT temperature sensor for a side project. The latest prototype (above left), is of a Huzzah ESP8266 Wifi Arduino board paired with a type-K glass braid thermocouple (MAX31855 breakout board). I was able to upload thermocouple temperature data via Wifi to an Azure IOT monitoring hub.

The original prototype (above right) used a infrared temperature sensor (MLX90614) with a micro pro trinket 3V Atmega328 Arduino. I played around with a 7-segment display in order to view live temperature data in C / F, and interface buttons in order to set a threshold warning level.
