Various sensors, including ECG, SpO 2, gyroscope, PIR, temperature-humidity, and BP, collect data processed by an Arduino microcontroller ... Oxygen saturation (SPO 2), Passive Infrared Sensor (PIR), ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

All you generally need is the Arduino IDE, which already includes most of the popular libraries for interfacing with frequently used components like ultrasonic sensors and LCD modules. The ...

Unlike an Arduino board that requires external components ... a momentary push button, a USB mic, an LCD screen, a camera, and a speaker to build this project. Having plants indoors is calming ...

This paper presents an implementation of smart, and inexpensive human body temperature detector by using portable electric system based on Arduino UNO ... person walk near the IR sensor, and display ...

2. This design is based on Arduino Nano board and built around an I2C LCD (module1). It uses an Arduino Nano (board1), an IR sensor module, a 5V relay module, jumper wires, a breadboard, and a few ...

The display is a 1.14 inch TFT LCD screen. Its keyboard is designed ... There’s also a HY2.0-4P interface for adding I2c sensors including temperature, humidity, light, or pressure sensors.

sensor on the back of the anti-epidemic watch, with red light and infrared light waveforms, can detect the heart rate and blood oxygen concentration (SpO 2) of the user (21). The data are calculated ...

There are two IR sensors, an ultrasonic sensor, a temperature sensor, LCD display and an Arduino UNO board used in this project. The temperature sensor will measure the person's body temperature, ...
