# 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

Create a session object, add an analog input channel, with the `'accelerometer'` `MeasurementType`.

```s = daq.createSession('ni'); s.addAnalogInputChannel('Dev4', 'ai0', 'accelerometer') ```
```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 = 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) -490 to +490 Gravities ```
