ESP8266 NodeMCU ESP-12E interrupts dont work properly

Trying to use interrupts on ESP8266 NodeMCU ESP-12E
Here is waveform https://www.youtube.com/watch?v=sGJrUbsZiQ4
and here is code
I should be getting a positive pulse around 1/sec but the interrupt counter is going up 10 or more a sec.
I have the hall effect/amp/schmitt trigger circuit and nodemcu on the same 5v supply.
Any ideas why this isn't working ?

{
pulseCount++;
Serial.println(pulseCount);
}
void setup() {
#define DIGITAL_INPUT_SENSOR D2
// initialize our digital pins internal pullup resistor so one pulse switches from high to low (less distortion)
pinMode(DIGITAL_INPUT_SENSOR, INPUT);
attachInterrupt(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), onPulse, RISING);
Serial.begin(9600);
pulseCount = 0;
}
