How do i remove the noise from this signal? or apply fft on it? Theres no relation between time and voltage. Aim is to: remove noise, smooth the signals, then detect peaks.

you can use a lowpass filter to smooth the signal, but it affact you to detecct the peak. FFT is used for periodic signals, and it may not perform well in your application.
