Components
Description
Arduino Uno
An open-source microcontroller based on the 8 bit ATmega238p microchip. It will work as an interface between the sensor and the mobile application described in this paper. This consists of additional components that help the microcontroller, such as a crystal oscillator, serial contact, voltage controller, etc. The Arduino Uno has 14 pins, including 6 pins for analog input, a link to the universal serial bus (USB), an ICSP header, and a reset button. The Arduino Uno provides an ICSP case.
Max 30100
The MAX30100 is a pulse oximetry and heart rate monitor sensor that can be powered by 1.8 V or 3.3 V power supply. A host microcontroller uses the I2C interface to communicate. The MAX30100 pulse oximetry subsystem consists of the ALC, a 16 bit sigma-delta ADC, and a patented disconnected time filter. It is ultra-low-powered, making it suitable for systems operating on batteries.
LM35
The LM35 is an integrated circuit temperature sensor with a temperature-dependent output voltage. It’s a compact, low-cost IC that can determine temperature anywhere between -55 and 150 degrees Celsius. It can easily be interfaced with any ADC or development platform, like an Arduino microcontroller. It can be linked.
Bluetooth module HC-05
The HC-05 is a module that can provide wireless functionality. We are using this module to set up communication between the Arduino and the mobile application. The HC-05 module can easily be coupled with microcontrollers because it uses the serial port protocol (SPP). Power the module simply by using +5V and connecting the module’s rx pin to the tx and the tx module pin to the MCU rx, as shown below.
LCD display
A 16 × 2 LCD display with I2C can show 16 characters in 2 lines. This means that you will only have four pins for the LCD display: VCC, GND, and SDA, as well as SCL.
Jumper wires
Without the requirement for soldering, flexible wire with connections on each end can be connected to other jumper wires or a pin header.
