Visualizing room temperature pattern with IoT

On my desk there is an IoT device that measures temperature and log data to the Internet. It is a hobby project build with Texas Instruments MSP430 series MCU, with an IR temperature sensor TMP006 (Infrared Thermopile Contactless Temperature Sensor) also from TI.

The temperature data are published via an OpenWRT TP-Link router to Exosite which is running a partnership program with TI on IoT services.

Last night I noticed something I never noticed before – a clear pattern of a less fluctuating period (around 19:00 to 21:00).

Possible cause: I turned off the fan to go dine out. When I’m back the fan is back on, added to the environmental factor that my body temperature and the turbulence from the fan lead to the fluctuation – just wild guess, it’s weekend 🙂
