High value readings when I have almost anything else in my code. about pulsesensorplayground HOT 1 CLOSED

@kathblair
Looking at your code, it seems that you are trying to measure the GSR sensor at a rate of 200Hz (every 5mS) is that right?
Also, it looks like when you comment out the temp code, you are measuring the temperature sensor once every loop.

It's very possible that your GSR and Temp code is getting stepped on by the Pulse Sensor interrupt.

First, you probably don't need to sample the other sensors as often as you seem to be doing. both the temperature and gsr values will change rather slowly, and when you sample fast you get a lot of noise.

If you insist on sampling those other sensors, you might want to try building off of the BPM_Alternative code example. That code uses a software timer to time the Pulse Sensor samples. Using that would mean that all of the analog reads that you do are initiated from the loop, and they won't be stepping on each other.

Please try that and reply back if it fixes the problem, then we'll know how to move forward. There are a couple tools in the interrupt driven code that could help if that's true.

Also, please send a pic of your hardware setup so I can verify your Pulse Sensor hardware
