As you may expect, the brains behind this operation is an Arduino ... In this case, the temperature is read by a LM35 temperature sensor and that value, along with the time, is recorded to ...

The LM35 temperature sensor and red led are powered with 5V from the Arduino board. As you can see in the sketch on the first line I included the LiquidCrystal library (header) that includes useful ...

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 ...
