# Sensor Events

The following list contains the names of all sensor events' parameters. With these names, you can filter your events and build amazing functions and interactions with Misty!

For example in the bump sensor Python function, to select a specific bumper you need to create an if statement where you verify: 

```python
if data["message"]["sensorId"] == 'bfr':
    #actions
```

 On this page, you'll get all the information about the name of the parameter, the comparison operator and the comparison value: 

### ActuatorPosition 

```python
 ActuatorPosition Event:
        ArmLeft = ("SensorId", "=", "ala")
        ArmRight = ("SensorId", "=", "ara")
        HeadPitch = ("SensorId", "=", "ahp")
        HeadRoll = ("SensorId", "=", "ahr")
        HeadYaw = ("SensorId", "=", "ahy")
```

### BumpSensor

```python
BumpSensorPosition Event:
        BackLeft = ("SensorId", "=", "brl")
        BackRight = ("SensorId", "=", "brr")
        FrontLeft = ("SensorId", "=", "bfl")
        FrontRight = ("SensorId", "=", "bfr")
```

### CapTouch Sensor

```python
CapTouchPosition Event:
        Chin = ("SensorPosition", "=", "Chin")
        Scruff = ("SensorPosition", "=", "Scruff")
        Right = ("SensorPosition", "=", "HeadRight")
        Left = ("SensorPosition", "=", "HeadLeft")
        Back = ("SensorPosition", "=", "HeadBack")
        Front = ("SensorPosition", "=", "HeadFront")
```

### TimeOfFlight

**Distance**

```python
    TimeOfFlightDistance Event:
        MinDistance = ("DistanceInMeters", ">=", value)
        MinDistance = ("DistanceInMeters", ">=", value)
```

**Position**

```python
TimeOfFlightPosition Event:
        FrontLeft = ("SensorPosition", "=", "Left")
        FrontRight = ("SensorPosition", "=", "Right")
        FrontCenter = ("SensorPosition", "=", "Center")
        Back = ("SensorPosition", "=", "Back")
        DownwardBackLeft = ("SensorPosition", "=", "DownBackLeft")
        DownwardBackRight = ("SensorPosition", "=", "DownBackRight")
        DownwardFrontLeft = ("SensorPosition", "=", "DownFrontLeft")
        DownwardFrontRight = ("SensorPosition", "=", "DownFrontRight")
```

**Status**

```python
TimeOfFlightStatus Event:
        MinStatus = ("Status", ">=", value)
        MaxStatus = ("Status", "<=", value)    
        StatusEqual = ("Status", "=", value)
```

### Face Recognition

```python
FaceRecognition Event:
        Label = ("Label", "=", "your_name")
```

### Object Detection

```python
ObjectDetection Event:
Description = ("description","=","knownobject_name")
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://lessons.mistyrobotics.com/python-elements/misty-python-api/sensor-events.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
