Arduino Project: IR thermometer using the MLX90614 IR temperature sensor from icstation.com

In this video we learn how to build a very usefull project. An Infrared thermometer, using the MLX90614 IR temperature sensor and the a Nokia 5110 LCD display shield. We are also using an Arduino Uno but you can use any Arduino board you like.

The project is capable of measuring the temperature of an object without touching it, from a small distance. It can measure temperatures from -70 degrees Celsius to 380 degrees. The accuracy is about 0.5 degree in room temperature which is great! Let's see the project in action. If I point the sensor at the cutting mat, the temperature it measures is

Now, if I point the sensor at my palm, the temperature rises to …. . You may wonder why it does not measure 36.6 degrees Celsius. That's because the skin temperature of a human, is different of the body temperature which is 36.6. The normal skin temperature of a person is between 32 and 35 degrees Celsius. Let's measure the temperature of more objects…. Cool isn't it?

Let's now see how to build this project. All we need is an Arduino Uno, the Nokia 5110 LCD shield and the MLX90614 IR sensor module. The sensor uses the I2C protocol so, it is extremely easy to make it work with Arduino.

Thanks Nik, I am discovering a new Arduino shield every saturday - thanks to your videos. Keep up the good work.

Great quick tutorial with the necessary explanations - thank you and keep bringing them.

Hello. Great channel and much appreciated. I will be using the mlx sensor to monitor the cheek area of someone's face to measure the response of skin temperature from transient emotional stress in psychometric testing. This involves custom digital filters of my own design.

Keep up the good work. Good I love this stuff.

Watching this to make device to help with corona outbreak

Hello sir may I ask if the Library for IR sensor for MLX906 is compatible with different IR sensor? Thank you sir

[muhd_fakhrulh]

can that MLX90614 IR sensor module be use on the arduino mini pro / arduino pico?

[deepakpandit]

Can I use this sensor as a person counting system?
using body heat

[Deejaydagting]

Greetings sir. Do you have any idea on how to implement this mlx90614 to an FPGA De0-nano board?

[yamaharblue]

How hard would it be to change the display to max temp during the period and also would it be possible to add 3 more IR sensors and display all 4 on the screen? Yes I'm a Noob. Thanks.

no encuentro la pantalla ¿se puede hacer sin la placa shield?

[ineffableseul]

is it possible to make infrared thermometer to be waterproof?

[fqenpzt]

it gives me error ( conflicting declaration ' const unsigned char uic []

[syafiqimran]

how can i simulate this mlx90614 in proteus simulation... plissss help me

[er.jugalmandal]

and its and your channel all videos are awesome

[oolesh]

hello I really love your videos!! I learned a lot from you thank you so much!!!

[gettic]

super video's, easy to understand and you use :D

[mangaluli]

Whats the maximum Temperature this can detect?

[encino]

Hello thankyou very much for this video. As a complete beginner it was very useful. Could you please tell me what sort of code I would need to play a sound when temperature reaches a certain number?

[fawadsami]

can this project be used in an industry ?
