Sometimes you need to know the temperature of something from a distance. It may be a smoker, a barbecue, or even a rabbit nest. This project from [the cautious mayor] may be exactly what you want.
[cautious mayor] monitor meat remotely, but don’t chatter endlessly.
It consists of a max31855 thermocouple amplifier, which is designed to work with common K-type thermocouples. It is connected to Texas Instruments cc1312 microcontroller, which sends thermal measurements through 802.15.4 protocol, which is the basis of ZigBee and thread technologies. It can send radio information over a long distance without using a lot of power, so that the project can use cr2023 coin cell battery. Coupled with the firmware of the dormant system when the system is not measured, [discreet mayor] expects the project to run on a battery for several years.
This information is extracted and recorded in the grafana setup, where it can be easily drawn. In order to increase utility, any temperature beyond the preset range will trigger the smartphone alarm through ifttt.
Paying close attention to temperature is the key to making delicious food with smokers, so this project should serve [the cautious mayor] well. For others who want to remotely monitor the temperature with the least trouble, it should also be done well!
