CHAPTER 5

IMPLEMENTATION AND TESTING

5.1 ImplementationIn this Medical Devices project using IoT System programming is used on

Arduino IDE microcontroller. The results of this project contains four

designs, namely:

1. MAX30100

2. MLX90614

3. ESP8266

4. SIM900A

5.1.1. MAX30100Results of the design of heartbeat series MAX30100 series on Arduino

Uno can be seen in the following figure:

Illustration 5.1: MAX30100

22

The heart rate sensor of the MAX30100 series uses a positive

voltage of 3.3 volts and a negative voltage coming from Arduino Uno in

the GND port. Then both cables are connected to port A4 which means

SDA and port A5 which means SCL in Arduino Uno. SDA is serial data,

while SCL is synchronous clock path. After that, because the MAX30100

requires a voltage to communicate I2C then the pull up is connected to 5V

arduino uno directly and given the resistance(resistor) equal to 10K on

SDA and SCL in the sensor.

5.1.2. MLX90614The design results of infrared body temperature sensor series

MLX90614 on Arduino can be seen in the following figure:

Illustration 5.2: MLX90614

23

The MLX90614 series body temperature sensor uses a 5 volt

positive voltage and a negative voltage coming from Arduino Uno in GND

port. Then means SDA and port A5 which means SCL in Arduino Uno.

SDA is serial data, while SCL is synchronous ctwo cables taken from the

SDA and SCL sensors are connected to port A4 which lock path.

5.1.3. ESP8266

Results of ESP8266 serial wifi design module on Arduino can be

seen in the following figure:

On ESP8266 it takes 3.3 volt voltage. In addition, ESP8266 also

requires RX and TX. Here RX and TX on ESP8266 are connected on pins

10 and 11 as communication between ESP8266 and Arduino Uno.

Illustration 5.3: ESP8266

24

5.1.4. SIM900AResults of GSM Shield SIM900 series design on Arduino can be

seen in the following figure:

In series GSM Shield 900A connected with 5 volt voltage and

negative voltage coming from Arduino Uno in GND port. Here ESP8266

is also connected simultaneously with SIM900 which usually receive data.

ESP8266 and SIM900 both require TX and RX, but the serial hardware

contained in the Arduino has only one pair. The devices in Arduino Uno

are actually only recommended for use on one module only. If in one

module using two serial software at once classified as ineffective in the

process.

5.2 Testing

In this testing, experiments were carried out on the heartbeat of the

MAX30100 series, the MLX90614 body temperature sensor, the ESP8266

wifi module, and the GSM Shield SIM900A.

In this project there are three testing, namely:

5.2.1 Functional testing

The results of the heart rate test rate of MAX30100 compared with

manual experiment with pulse in hand, infrared temperature sensor series

MLX90614 compared with thermometer experiment up to 10 respondents.

The ESP8266 data transmission experiments connect on wifi and send data

to the thingspeak server' and hosting server . Send an SMS experiment to a

different provider using Modul GSM SIM900A series. Trial server system.
