How to remove sensor drift?

I have taken continuous readings of body temperature from the temperature sensor. I have observed that there is a drift of the temperature value during baseline reading. What are the methods that I could eliminate sensor drift??

I don’t know if I understand your question well, maybe your can try to use Linear Interpolation to smooth the data you read.

Thank you for the information !!!

I had a similar problem with strain gauges, but in my case the cause was increased electric conductivity due to the sensor heating up over time due to body heat. In my case, i had to use a baseline sensor, that isn‘t fixed, so only got a change due to temperature. Then just subtract that value and you got the right value.

That is a good idea. I also realized that to use a separate temperature sensor to measure ambient temperature. Therefore, subtracting values will give the change of the body temperature only.
