Introduction: Use Smartphone As Non Contact Thermometer / Portable Thermometer

Measuring body temperature with non-contact / contactless like a thermo gun. I created this project because Thermo Gun now is very expensive, so i must get alternative to make DIY. And the purpose is make with low budget version.

Supplies

  • MLX90614
  • Arduino Nano
  • OTG Micro to mini usb

Step 1: Wiring Connection

MLX 90614 have i2c communication, so in Arduino Nano use pin A4 & A5

Step 2: Prepare Library MLX90614

for library MLX90614 i use adafruit library, you can Open Arduino IDE and menu Tools -> Manage Libraries -> search MLX90614. and click Adafruit MLX90614 Library then click install in Library Manager

Step 3: Program Arduino MLX90614

Open Arduino IDE, Click File -> Examples -> Adafruit MLX90614 Library -> mlxtest.

Upload then see serial Monitor, you can see Ambient temperature and object temperature

Step 4: Prepare Circuit, OTG, and 3D Print Cover

After sample MLX90614 code work, prepare circuit between arduino nano and mlx90614 sensor like a picture. For OTG you can make DIY with Male Microusb and Male Miniusb

Cover Portable Thermometer can download file 3D in https://grabcad.com/library/portable-thermometer-box-1 and print with your 3Dprint Machine

Step 5: Upload New Code Arduino

Step 6: Install App Portable Thermometer From Playstore

You can search in playstore "portable Thermometer" or you can click this link Portable Thermometer or you can scan this qr-code

Step 7: Running Portable Thermometer

How to running Portable thermometer

  • Connect device in your smartphone with OTG.
  • active OTG Connection in your smartphone
  • Run application
  • click check now to check body temperature

Step 8: Video Project Portable Thermometer
