# Sensitivity

Sensitivity of an analog channel

## Description

When working with the session-based interface, the Sensitivity property to set the accelerometer or microphone sensor channel.

Sensitivity in an accelerometer channel is expressed as $\frac{v}{g}$, or volts per gravity.

Sensitivity in a microphone channel is expressed as $\frac{v}{pa}$, or volts per pascal.

## Examples

```s = daq.createSession('ni');
```
```Data acquisition session using National Instruments hardware:
Will run for 1 second (2000 scans) at 2000 scans/second.
Number of channels: 1
index Type Device Channel      MeasurementType             Range        Name
----- ---- ------ ------- -------------------------- ------------------ ----
1     ai   Dev4   ai0     Accelerometer (PseudoDiff) -5.0 to +5.0 Volts```

Change the Sensitivity to 10.2e-3 V/G:

```ch1 = s.Channels(1)
ch1.Sensitivity = 10.2e-3
```
```s =
