DESC:TECHNICAL FIELD
[001] The embodiments herein generally relate to water purifiers and more particularly, to a system and a method for monitoring the water purifier, where the system is detachable and can be retrofitted to any type of water purifier.

BACKGROUND
[002] Along with the aggravation of environmental pollution, drinking water safety is more and more emphasized, unclean drinking water has huge harm to human health, and the TDS value in the drinking water becomes the key point of attention. Water purifiers and the like having a water filtering function are being introduced into homes by many users. Most of the water purifiers popularized in the market only have the functions of water filtration and purification, do not have the function of water quality detection, and users cannot know the condition of water quality at any time, so that filter elements cannot be replaced in time. Although some high-end water purifiers are internally provided with monitoring devices and have a water quality monitoring function, the high-end water purifiers are very expensive and cannot be popularized in a large area, and the traditional water purifiers popularized in a large area are discarded and replaced with high-end water purifiers with high prices, which is one of the main reasons that the high-end water purifiers cannot be accepted by most users. Further, the high-end water purifiers are subjected to high water wastage and the amount of water wastage is not known to the users. Therefore, some external monitoring equipment on the water purifier appears in the market, but the structure of the monitoring equipment is very complex and is provided with two water paths. When the external monitoring equipment is used, the filter element needs to be replaced after two conditions that the water quality is detected not to reach the standard and the total flow of filtered water of the filter element reaches the set flow are met. Therefore, the equipment has the disadvantages of various parts, higher cost, large volume and inconvenience in installation.
[003] Therefore, there exists a need for a system and a method for monitoring a water purifier, which obviates the aforementioned drawbacks.
