4 years ago I love this idea. My SleepIQ bed gives me heart Rate and Breathing rate data points and I can see elevations in heart rate days before actually getting symptomatic sick.

4 years ago @CCOSTAN, I didn't want to turn into a cyborg and don't plan to use this anywhere other than my home so thought I'd keep it simple. I've ordered a stretch fabric armband which I plan to add an Aqara temperature sensor too. I'll tear the sensor down outside of its case to allow closer contact to the body surface. I should have a working prototype tomorrow. Looking forward to seeing the results. With regards to heart rate, I have been considering seeing if my Wahoo heart rate monitor publishes the heart rate over BLE. If it does this would be neat for the maker scene and a great companion to the body temperature sensor.

4 years ago Not sure it makes the grade. The thing I found with the Aqara temperature sensor is that it isn't easy to have it in contact with the skin without using a lot of pressure due to how it is placed on the PCB board.
So now I need to go back to the drawing board and possibly even up the cyborg state a little. But even this simple test has got me thinking about IoT in healthcare and how beneficial making data available realtime is. Particularly now with COVID19 in minimising cross infection and improving medical professional productivity by having data readily available.

python heart_rate_monitor.pyAfter modifying the above python script to publish the BPM to an MQTT topic I was able to access the data in Grafana.
Objective
Our body temperature gives us a good indication of how well we are. It is also a sign of stress and many other things and I'm curious about the data. With a shortage of thermometers likely due to CONVID19 I'm curious if I can build a wearable thermometer to allow me to get some sample data. Other wearable devices like my Apple Watch provide me with data such as exercise (or lack of in my case) and heart rate but not my body temperature. If I get something that provides reliable data I thought it would be useful to keep to monitor when if I fall ill someday.
Adults. Among adults, the average body temperature ranges from 36.1°C to 37.2°C (97°F - 99°F).
