@Wolffyx This is quite a simple sketch, and I don't see how there could be a conflict between the temp sensor and the Pulse Sensor. Try increasing the baud rate? Set it at 115200 and see if that helps? Also, you could try to use a different sketch, like the PulseSensor_BPM sketch. Modify it so that it only prints the Pulse Sensor BPM values and the Temp values, and then look at the Serial Plotter? Also, you should try to have the sketch print the raw Pulse Sensor signal as well as the temp values to the serial plotter so you can see what is happening to the signals. That might provide a clue.
Also, please send along a picture of your Pulse Sensor so I can verify that it is legit.
Here is a pic with the pulse sensor .Tried the PulseSensor_BPM sketch same problem .
@Wolffyx Thanks for the picture. It explains alot. You are not using an Official Pulse Sensor. I cannot help you troubleshoot your problem, because I have no idea what is in that hardware. Please support the original makers and purchase legit Pulse Sensor. You can find them at these internet locations. www.pulsesensor.com www.adafruit.com www.sparkfun.com www.amazon.com www.mouser.com www.digikey.com
I am trying to combine the two sensors (pulse sensor and LM35 temp),but there is a problem with them when is a noise at the pulse sensor .The values are fluctuates especially the LM35 it goes from 31 degrees (normal value ) to 25-50 and even the pulse one . Here are the results . The code is this(I got the code form the Getting_BPM_to_Monitor sketch and added the LM35 code)(board is Arduino Uno) :
