Just one correction: MLX90614 accuracy is not very high - it is 0.5°C, but you can get version with accuracy of 0.2°C (not 0.02°C) in a limited temperature range around the human body temperature. However this is still very cool and useful project!!
@@HowtoElectronics Actually even with offset compensation, and the sensor Emissivity set to "0.98" according to it's datasheet "for human skin", it's still inaccurate! However I got my hands on the MLX90614ESF-DCI (supposedly medical grade) and it's accuracy is not what I expect.... even tho this is little more stable than the regular one.... My code has some functions that will get some samples (10 to 50) and calculate the average temperature, and even with that it's not working 100% of the time as expected (that's because I'm using a medical IR thermometer to compare the measures and adjust the offset!) One interesting point is the medical IR thermometer, the internal sensor is a little small than the MLX90614, and it has only 3 pins, so it may works with PWM... not sure... I may try to reverse engineering this thing one day...
Actually he was sitting in front of the Air Cooler and room temperature was around 27deg. For calibration we have to compare the value of some standard thermometer and add some calibration factor in the code.
Good Job po sir/ma'am I request for you that show or share me your Schematic Diagram and Code your work in this DIY infrared Thermometer because I need your diagram in May Project School thank you.
Sorry to ask, can i know is possible to use body temperature sensor ,heart rate sensor and spo2 sensor connect to ardiouno uno and then ardiouno connect to wifi module and gsm module. The wifi module will send input data to think space and gsm module send sms to phone in case on red alarm

Actually we can calibrate the sensor in code part comparing the reading of any standard sensors.
@@HowtoElectronics Interesting, I was not aware of this. So, after calibration you can get better precision? In that case this is excellent!

Thank u for this video ..such a wonderful equipment in covid-19 situation..superb voice cover..😍
Cool project, but if your friend is 30 degrees Celsius he is a rapidly cooling corpse. Is there way to correct the temperature offset?

Can you show us about water quality device like Ph value, oxygen level, ammonia level, water temperature.
Thanks
Nice project
Awesome great project. Very useful during Covid-19. You could have made this video few months back, that would have been great.
Thank you so much once again for this very informative and useful gadget 🥰🥰
Hi, Can I know how to calibrate the sensors as the reading is not too accurate.
he should around at 35-6℃ even the room temp. is pretty low.
you got new sub,,,....
good keep working hard....
Keep supporting Nepali brothers
Hi dear friend. How many degrees does it measure? Thank you for the video.
Nice one bhai
Wow!!
How did you programme the pro mini? Where is the code?
thanks for sharing. Does the MLx90614 have a duty cycle? can it be left on for 24/7 for temp logging with out burning out the IR.
thank you
good work
I have this temperature sensor but the standalone one without pcb how can i use it for this project?
Hi , i need to built this thermometer with microcontroller and without Arduino , can you help me
the measured forehead temperature is 30.xx degree c?
बहुत खूब भाई☺️♥️❤️

What are the Certification, is it approved by WHO is it Chinese.
You can use this for personal application. And MLX90614 Sensor is used in the device approved by WHO.
How to draw that circuit diagram and connections ?? can anyone tell me its urgent!!
If we replace the battery with 3.7 v to 9v
Which jumper wire is used?
I want MLX90614 library for proteus.. please share the link..
can we use ISB-TS45D sensor instead of MLX90614 sensor because MLX one is too expensive??
You can use any sensor. But you need good programming skill to use that sensor with microcontroller.
Sir pleace add circuit diagram
This is awesome. But I have one issue. Can you please change your intro? It has become old and it irritates a lot.
hahaha, thanks for feedback bro. We will soon make a new one.
What is the use of laser in this system?
To point the object
Good Job po sir/ma'am I request for you that show or share me your Schematic Diagram and Code your work in this DIY infrared Thermometer because I need your diagram in May Project School thank you.
The link for code and circuit is given in description.
30C - это нормально??
Any way to get the STL file?
The file link is given in website article. You can visit from the link in description.

Yes you can upload the data to server for max30100 and mlx90614.
