GETTING STARTED WITH CJMCU-30205 MAX30205 Body Human Temperature Sensor

In this tutorial we will use CJMCU-30205 MAX30205 temperature sensor to measure body temperature.

Step1: Hardware required

• Arduino UNO
• CJMU-30205 Body human temperature sensor
• Jumper wires

Step2: Connecting the Hardware

Wire the MAX30205 breakout board to an Arduino Uno(or equivalent) using the following connections.

Arduino	MAX30205 Breakout board
5v	Vin (3.3V is also supported, change solder jumper behind the board. Default will be 5V)
GND	GND
A4	SDA
A5	SCL

Step3: CJMCU-30205 MAX30205 Library setup

Before making the sketch make sure you have the Protocentral_MAX30205-master library if not, you can download it here .

After download the library extract it to the arduino library folder as shown below

Step4: Upload the sample sketch

1. Open the Arduino IDE to load the embedded code for Protocentral_MAX30205.
2. Click on File -> Open and Browse the .ino code for Arduino from Protocentral_MAX30205-master\arduino and export the application to Arduino.

Step5: Testing the circuit

Open serial terminal window, you should see the temperature values obtained from the Protocentral_MAX30205 Breakout Board as shown below.
