^70 - The Humidity Port

This port is a read only value of the current humidity.

This value will include any temperature offset configured in the device properties. It is not a raw value.

Syntax

LDA ^70,0 For the whole value
LDA ^70,1 For the fractional value

The value fluctuates wildly within a few percent. System Builder smoothens this out when broadcasting the value.

Example

Example of a task checking the current measured humidity.

Task1()
{
LDA ^70,0     // Get the whole number humidity percentage.
CMP #70       // Compare to 70%
BCC TooHumid    // If greater than or equal to the 70% it is too humid
CMP #50         //Compare to 50%
BRC JustRight   //If below or equal to 50% it is comfortable
Null
TooHumid:
    StartTask(2)    //Go start dehumidification task (usual fan low AC on)
    Null
JustRight:
    StartTask(3)    //Go start task to return HVAC to previous settings
    Null
}
