Three features of micro technologies

The use of micro technologies has revolutionized the way the human being is able to conduct his or her life on the domestic front, in the work place and for personal health reasons. Technologies in place are not only faster, they are more reliable too. This is pertinent where smart technology powered monitoring devices are concerned. It remains critical that such monitoring devices’ ability to make recordings of the human body’s vital signs remain accurate.

Three among many features of micro technologies help make this possible. This short article highlights low battery detection, rapid change detection and hysteresis. Interested readers place themselves in a better position to understand more when they explore further authoritative online guides that explain in full how micro technologies are put to use. Hysteresis can briefly be explained as a sensation of ‘chatter’.

This can happen when external noise and switching noise within a microcontroller occurs. This happens when a comparator’s input voltages are almost equal. A comparator can be defined as a smart monitoring device in layman’s terms. Micro technology’s comparator-based circuits are able to identify when a device’s battery is experiencing an insufficient charge that can disable important device functions.

Rapid change detection entails the ability of a comparator to not only identify a charge but also determine when a change in charge or voltage occurs. A copy of output is stored which allows for intermittent comparisons of held values to actual outputs which can control the change in battery or voltage charge. Using a single comparator within a microcontroller allows for much faster detections of change.

Dealing with low battery detection is also improved when a similar circuit from a comparator is placed in the microcontroller particularly when a low voltage detect peripheral is not featured.
