TE HTU21D Element
The TE HTU21D element is used to read Ambient Temperature and Humidity.
SECTION FOR EELS ONLY, uncomment for EELS The [name] is a sensor element that can be imported into the Element Toolbox through the Add Elementbutton located in the toolbox from Embedded View.
The following properties can be changed for the TE HTU21D element:
The name of the element.
I2C Driver Instance
I2C driver instance to use for communication.
GPIO Driver Instance
GPIO driver instance to use.
TE Weather Shield
This sensor is included on the TE Weather Shield, which requires 3 extra GPIO lines to be used as a “chip select”. If this is set to false, the following 3 properties will be ignored.
Weather Shield CSA
Weather Shield Chip Select A GPIO Pin. Ignored if TE Weather Shield property is set to false.
Weather Shield CSB
Weather Shield Chip Select B GPIO Pin. Ignored if TE Weather Shield property is set to false.
Weather Shield En
Weather Shield Chip Select Enable Pin. Ignored if TE Weather Shield property is set to false.
The following triggers are available to execute events from within the TE HTU21D element:
Execute an event when the source element connected to the TE HTU21D triggers.
Execute an event when the temperature is read from the TE HTU21D.
Execute an event when the humidity is read from the TE HTU21D.
The following abilities are available for the TE HTU21D element when its source element triggers:
Trigger the element(s) that follow the TE HTU21D element.
Read the temperature in degrees Celsius.
Read the humidity in % relative humidity.
