I'm looking for a sensor to use as body heat sensor for medical project
Hi everyone, I'm looking for a sensor to use as body heat sensor for medical project, I'm trying to use LM35 with esp32 and IOT system but my problem is that I don't find it suitable (casing)
So any suggestions on what to use, and thank you in advance

You will need a PPG for the SpO2 & heartbeat - but yes, it will work with them in parallel

Hey @aymen ammari I found this for you, it has higher temperature range and a very precise accuracy and a temperature tolerance of +-1%.

What kind of casing type are you looking for. And where will it be placed
I'm using one of these in a medical device for one of my projects

I want to design something to stick on my finger to measure temperature / heartbeat / SPO2 All at the same time
It can work with Max30102 in parallel right?

What is PPG? 🤔
It's photoplethysmogram - https://en.wikipedia.org/wiki/Photoplethysmogram
Here's an article on it's use - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6426305/
Photoplethysmogram
A photoplethysmogram (PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue. A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. A conventional pulse oximeter monitors the perfusion of blood to the dermis an...

Photoplethysmography (PPG) is an uncomplicated and inexpensive optical measurement method that is often used for heart rate monitoring purposes. PPG is a non-invasive technology that uses a light source and a photodetector at the surface of skin to measure ...
Great. The sensor I sent should be a good one.
Thank you, this helps a lot
