A thin wrapper around the Android Sensor APIs

Compose Sensors

This library is a thin wrapper around the Android Sensor APIs, designed to make it easier to work with them in Jetpack Compose.



In module build.gralde.kts file:

dependencies {

The library is available via mavenCentral(). Versions can be found on the releases page.

Core APIs

The core APIs provide composable access to the Android sensor framework classes:

// Get the SensorManager
val sensorManager = getSensorManager()

// Check if a certain type of sensor is available
val available = isSensorAvailable(type = Sensor.TYPE_ACCELEROMETER)

// Get a sensor
val sensor = getSensor(type = Sensor.TYPE_ACCELEROMETER)

// Remember a sensor value as State that updates as SensorEvents arrive
val sensorValue by rememberSensorValueAsState(type = Sensor.TYPE_ACCELEROMETER) { event ->
    // Transform SensorEvents

Per-sensor APIs

The per-sensor APIs build on the core APIs and provide convenience by:

  • Not having to pass the sensor type parameter
  • Handling the transformation of SensorEvents for each type of sensor, by using the SensorValue class
// Check if accelerometer sensor is available
val available = isAccelerometerSensorAvailable()

// Get accelerometer sensor
val sensor = getAccelerometerSensor()

// Remember accelerometer sensor value as State that updates as SensorEvents arrive
val sensorValue by rememberAccelerometerSensorValueAsState()
// Accelerometer sensor values. Also available: sensorValue.timestamp, sensorValue.accuracy
val (x, y, z) = sensorValue.value

The following sensor types are available:
