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
