Statement
I want to be able to test sensors, by turning on a related device that would trigger the sensor, so that I can be assured that the sensor is working.
Background
Some sensors can be 'tested' to cause a temporary spike in their measurements to ensure that they are functioning properly (at least, that false negatives are not an issue). Suggested method for doing this, is to have the test method turn on some type of actuator that would cause an increase in the sensor's measurements (LED shone on a photosensor for example).
Acceptance Criteria
That, when this action is called:
- That the test actuator is turned 'On'
- That is is turned on during the period of measurement (I don't want a piezo buzzer ringing for an hour)
- That the test actuator is turned on for the specified number of test cycles
- That the test on state is captured when measurements are taken (to distinguish between test and real data)
