The advantages of light sensors is that they are really good security systems. The disadvantage of them is that they're really easy to set off.
The advantages are that:1. They are vary useful in security problems.2. They protect things.3. sensors can be placed in dangerous location where people can be hurt.4. sensors can record data that people do not senseaccurately such as humidity.
disadvantage of ECG is that there are so many rays are passed from our body and these are very effective for our health the advantage of electro cardio graph is that from this we know the disease of heart
Advantages-Many things are controlled by infrared. sensors are invisible to the naked eye and are very reliable. Disadvantages- Most infrared sensors must be lined up or they will not work

It's situation dependent.
ECG stands for ElectroCardioGram
SENSORSAdvantages:It can accomodate new devices at anytime.Very accurate.Disadvantages:Expensive .Self heating.
Never. An ECG is a test, not an illness or disease.
An ECG provides information about the wearer of the ECG's heartrate and rhythm of the heart. It provides information about wether it is normal or abnormal.
