Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, ... R-C components R2-C1 is vitally necessary to suppress ...

This project builds a real-time stress detection system using a PPG sensor and Arduino UNO R4. Pulse data is processed in Python to extract features and predict stress with a Random Forest model.

The pulse output signal from these devices is, in essence, an on/off switch which changes state at a frequency related to the fluid flow. As well as discussing the different sensors primarily used in ...

This project uses an Arduino Uno CH340G clone and a DHT11 sensor to build a compact weather station that measures temperature and humidity, calculates over ten derived environmental metrics, and ...
