This isn’t about connecting a temperature sensor in your Arduino. This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno ...

In our case Arduino is the master and 3 x TC74 sensors are the slaves ... notice is that the data is already printed in degrees because this is a digital temperature sensor so we won’t have to do any ...

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 ...
