readTemperature

Read the temperature value from the Humidity sensor or the Air Pressure sensor

Syntax

temperature = readTemperature(mysh)

temperature = readTemperature(mysh,'usehumiditysensor')

temperature = readTemperature(mysh,'usepressuresensor')

Description

temperature = readTemperature(mysh) returns the temperature read from the Humidity sensor. This is the default syntax of the function.

temperature = readTemperature(mysh,'usehumiditysensor') returns the temperature read from the Humidity sensor that you specify as an extra argument.

temperature = readTemperature(mysh,'usepressuresensor') returns the temperature read from the Air Pressure sensor that you specify as an extra argument.

Examples

Read Temperature from Sense HAT

You can read the temperature from Sense HAT by using the following command.

readTemperature(mysh) 

ans = 

  305.0798 

Read the temperate from Sense HAT.

Read Temperature from Humidity Sensor of Sense HAT

You can read the temperature from Humidity sensor of Sense HAT.

readTemperature(mysh,'usehumiditysensor') 

ans = 

  305.0798 

Read the temperature from the Humidity sensor by specifying ‘usehumiditysensor’ as an argument to the function.

Read Temperature from Pressure Sensor of Sense HAT

You can read the temperature from the Air Pressure sensor of Sense HAT.

readTemperature(mysh,'usepressuresensor') 

ans = 

  304.3313 

Read the temperature from the Humidity sensor by specifying ‘usepressuresensor’ as an argument to the function

Input Arguments

mysh — Connection to SenseHAT

SenseHAT object

Connection to a SenseHAT board, specified as a sensehat object.

usehumiditysensor — Argument to specify that the sensor to read temperature from

Argument to specify that the temperature has to be read from Humidity sensor.

usepressuresensor — Argument to specify that the sensor to read temperature from

Argument to specify that the temperature has to be read from Air Pressure sensor.

Output Arguments

temperature — temperature

The temperature value read from the Humidity sensor or the Air Pressure sensor. The output of this method is a double and the unit of measurement for temperature is Kelvin (K).
