Properties
The following properties can be changed for the INA219 element:
Name
The name of the element.
I2C Driver Instance
The I2C bus used to communicate with the sensor.
I2C Address
The I2C address the element sends data to.
Shunt Resistor Value (Milli-Ohms)
The resistance value of the shunt resistor. The INA219 requires a calibrated resistor for the shunt.
Gain
The sensitivity gain for the sensor.
Voltage Range
The default voltage range for the sensor.
Bus ADC Resolution
The resolution (in bits) for the ADC that samples the sensor’ bus line.
Shunt ADC Resolution
The resolution (in bits), sample rate, and sample time for reading the shunt’s voltage. Increasing this value will make voltage readings more accurate, but will take longer to sample.
Triggers
The following triggers are available to execute events from within the INA219 element:
Triggered
Execute an event when the source element connected to the INA219 triggers.
Current Read
Execute an event when current data is read (in micro-amps).
Bus Voltage Read
Execute an event when bus voltage data is read (in milli-volts).
Power Read
Execute an event when power data is read (in milli-watts).
Shunt Voltage Read
Execute an event when shunt voltage data is read (in milli-volts).
Abilities
The following abilities are available for the INA219 element when its source element triggers:
Trigger
Trigger the element(s) that follow the INA219 element.
Read Current
Read the sensor’s current data.
Read Bus Voltage
Read the sensor’s bus voltage data.
Read Power
Read the sensor’s power consumption data.
