Embodiments include breath intoxicant monitoring systems and methods of operating a breath intoxicant monitoring system. In an embodiment, a breath intoxicant monitoring system, includes a first detection element, a second detection element, and a control module. The first detection element can be operable to detect a level of an intoxicant in a user's breath and to provide a continuous signal indicating the level of intoxicant. The second detection element can be operable to detect a level of the intoxicant. The second detection element includes a different type of element than the first detection element. The second detection element can have greater accuracy than the first detection element. The control module to selectively operate the second detection element based on the signal received from the first detection element, and to indicate whether the level of intoxicant in the user's breath exceeds a threshold.
