# Pulse Duration
# pulse Duration
Gets the duration of the last pulse in microseconds.
This function should be called from an **on pulsed** handler.
Get the duration of the last pulse in microseconds.
```sig
pins.pulseDuration();
```
### Returns
A pin pulse is detected in the [onPulsed](/reference/pins/on-pulsed) event. You use **pulseDuration** inside that event to get the duration of the pulse that triggered the event.
The duration of the last pulse, measured in microseconds.
### ~ hint
### Example
**Simulator**: This function needs real hardware to work with. It's not supported in the simulator.
The following example waits for pin ``P0`` to be pulsed high, and then
displays the duration of the pulse in microseconds on the LED screen.
