Hi, I was wondering if this ISR is too much for processing power of Arduino? The interrupt is set at 1kHz ISR(TIMER1_COMPA_vect) { //Interrupt at freq of 1kHz distance = getDistance(Lsensor); pressure = getPressure(Psensor); prSwitch = getPswitch(Pswitch); temp = getTemperature(tmp); …

Is this too big for ISR ?

It's nothing to do with processing power. Don't do Serial.print inside an ISR.
