After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

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 ...

The coaster uses a TMP006 infrared temperature sensor which measures the temperature of whatever you place on the coaster indirectly. It also doesn’t use much power.

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

Aside from the Uno and the ultrasonic sensor, you also need a PHPoC Shield to connect the board to the internet and a power supply to power up your Arduino.
