The system here monitors temperature, humidity, and smoke levels and alerts you if those levels reach a certain point.

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

First there were traditional temperature sensor ICs, but after deploying numerous nodes [Edward] was running into the limit of their accuracy. Could he use c lever code and circuitry to get better ...
