Fabricating my first temperature sensor board.

I have fabricated a wifi temperature sensor for my IoT project, IoT Plan.

The sensor board uses an ESP32 module for its core functionality: controller, wifi and temperature sensor. I paired it with a buck-boost voltage regulator that can be supplied by battery (3V) or micro-usb (5V) source. A 4-...

We live in a house built in the 60's, and we close off some rooms we rarely use to conserve energy. This year we have been tracking temperatures due to the installation of a new heating system. Wanting to collect more detailed measurements, I am creating a sensor network to collect temperatures auto...

Inspired by the short-comings of my first locked-in amplifier experiment, this is my plan to revisit the subject.

My main oversight in the first experiment was not quantifying the difference between measurements, both with and without noise, and to what degree the noise would have influenced out...
