Android Things driver for Sensirion STH2x series humidity and temperature sensor

NOTE: these drivers are not production-ready. They are offered as sample implementations of Android Things user space drivers for common peripherals as part of the Developer Preview release. There is no guarantee of correctness, completeness or robustness.

How to use the driver

Gradle dependency

To use the this driver, simply add the line below to your module's build.gradle.

dependencies {
    compile 'com.wusp.androidthings:sht2x:0.0.3'
}

This driver also need kotlinx.coroutines, add kotlinx.coroutines to module's build.gradle too.

dependencies {
    compile 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.17'
}

Sample usage

//Using i2c bus name to initialize SHT2x sensor
val p = PeripheralManagerService()
val device = SHT2x(p.i2cBusList[0])

val job = runBlocking {
    try {
        //read the humidity in not hold mode.
           val hData = device.readRHinNotHold()
           if (hData != null) {
               val humidity = convertToHumidity(hData)
           }
           delay(500)      //delay to execute
           //read the temperature in hold mode
           val tData = device.readTinHold()
           if (tData != null) {
             val temperature = convertToTemperature(tData)
           }
    } catch (e: Exception) {
        e.printStackTrace()
    } finally {
       device.close()  //close device to release resource
    }
}
