This isn’t about connecting a temperature sensor in your Arduino. ... or an artifact of the interrupts/code ... The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C ...

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 ...

By oversampling the Arduino’s ADC, an effectively higher resolution is obtained without adding any hardware or altering the voltage reference. Instead of reading the ADC once, the code reads the ...
