CHAPTER 5 IMPLEMENTATION AND TESTING

CHAPTER 5 IMPLEMENTATION AND TESTING 5.1 Implementation In 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. MAX30100 Results of the design of heartbeat series MAX30100 series on Arduino Uno can be seen in the following figure: Illustration 5.1: MAX30100 21

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. MLX90614 The 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: Illustration 5.3: ESP8266 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.

24 5.1.4. SIM900A Results of GSM Shield SIM900 series design on Arduino can be seen in the following figure: Illustration 5.4: SIM900A 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

25 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. 1.
