1. A sensor, comprising:
one or more components configured to:
determine a time interval between a time of reception of a first trigger to selectively transmit or sample first sensor data and a time of reception of a second trigger to selectively transmit or sample second sensor data;
determine, based on the time interval, a predicted time of reception of a third trigger to selectively transmit or sample third sensor data;
initiate a set of sensor tasks based on the predicted time of reception of the third trigger, the set of sensor tasks being initiated to cause the third sensor data to be ready for transmission at the predicted time of reception of the third trigger;
receive the third trigger;
determine a delay latency value associated with an amount of time from completion of the set of sensor tasks to an actual time of reception of the third trigger;
calculate a deviation of the delay latency value from a target delay latency; and
transmit a data frame including an indication associated with the deviation of the delay latency value from the target delay latency.
