Putting an old digital clock (with an outdoor thermometer) on steroids with ESP32 #ESP32

Michal Jirků owned a well aged digital clock with indoor/outdoor thermometer. The device deserved an upgrade.

First step is to figure out what protocol does the outdoor temperature sensor speak to the clock…  I scored on 433.9 MHz.

I turned to the final architecture.

I’m a big fan of HTTP. It’s easy to debug, ubiquitous, dead easy to target. So the following makes sense (to me):

Read about the implementation on the post here.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
