Personally, I have found indicators to be very useful in our everyday life. Indicators are forms of signals that represent various conditions in our world ranging giving an alert to indicating a position of an object. They come in different forms like digital displays, traditional lamps and needles.
Indicators have several important applications where they have enhanced safety, increased ease of use, and improved accuracy. For example, automobile indicators help to give an alert when another vehicle is behind while riding, while temperature indicators help to ensure that the exact temperature has been achieved in a given appliances. In addition, indicators such as fuel gauges, speedometers, rev counters, and pressure gauges, keep us informed about important conditions of our cars, helping us to remain safe and in control.
Indicators can also be used in medical equipments. Devices such as thermometers, blood pressure monitors, EEG monitors, and spirometers, provide indicators of the condition inside our bodies, helping the doctor diagnose and provide appropriate treatments for the patient. Furthermore, indicators can also be found in industrial applications such as control systems, wherein they monitor the process and control its variables.
In conclusion, indicators are useful as they provide us with various signals that inform us of various conditions, allowing us to take appropriate actions. Not just limited to safety, they can also help to increase accuracy, save time, and offer convenience. They are essential in many applications and are continuing to be developed with improved features.
