Arduino101Humidity 湿度和温度

Arduino101Humidity 湿度和温度组件让用户可以从 Grove DHT11 传感器收集湿度和温度数据。温度数据以摄氏度为单位，相对湿度以百分比为单位。

属性

• BluetoothDevice – The BluetoothLE component with a connection to the Arduino 101.

• Pin – The Pin on the Arduino board that the device is wired in to.

方法

• IsSupported – Tests whether the Bluetooth low energy device is broadcasting support for the service. If true, calls to TurnOn and TurnOff should work correctly. Otherwise an error will be reported through the Screen’s ErrorOccurred event.

• ReadHumidity – Read the current humidity from the attached sensor. On success, the HumidityReceived event will be run with the received humidity measurement.

• ReadTemperature – Read the current temperature from the attached sensor. On success, the TemperatureReceived event will be run with the received temperature measurement.

• RequestHumidityUpdates – Request notifications from the Arduino for changes in the humidity sensor reading. The HumidityReceived event will be run as samples are received from the Arduino.

• RequestTemperatureUpdates – Request notifications from the Arduino for changes in the temperature sensor reading. The TemperatureReceived event will be run as samples are received from the Arduino.

• StopHumidityUpdates – Stop listening for notifications of changes in the humidity sensor reading. This only has an effect if there was a previous call to RequestHumidityUpdates. There may be additional pending messages that will be processed by running HumidityReceived.

• StopTemperatureUpdates – Stop listening for notifications of changes in the temperature sensor reading. This only has an effect if there was a previous call to RequestTemperatureUpdates. There may be additional pending messages that will be processed by running TemperatureReceived.

事件

• HumidityReceived – The HumidityReceived event is run whenever humidity samples are received from the Arduino. This is usually a result of performing a read or request operation. The humidity value is a relative humidity between 0-100%.

Parameters:

 * <code>humidity</code> (<a href="http://appinventor.mit.edu/explore/ai2/support/blocks/math.html#number">_number_</a>) &mdash; The relative humidity, in percent.

• TemperatureReceived – The TemperatureReceived event is run whenever temperature samples are received from the Arduino. This is usually a result of performing a <a href=”#ReadTemperature>read</a> or request operation. The temperature value is measured in degrees Celsius.

Parameters:

 * <code>temperature</code> (<a href="http://appinventor.mit.edu/explore/ai2/support/blocks/math.html#number">_number_</a>) &mdash; The temperature, in degrees Celsius.
