This isn’t about connecting a temperature sensor in your Arduino. ... The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

The new e-Health sensor platform adds sensing capability for nine different biometric parameters, such as pulse, blood pressure, oxygen in blood (SPO2), electrocardiogram (EKG), airflow ...

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 ...
