control of lighting, heating or blinds is done according to a time schedule, the Arduino RTC happens to be an indispensable chip.<\/p>\n<h3>3. data loggers<\/h3>\n<p>Arduino RTC is used in data loggers that need to accurately track the time and date of events, such as temperature, humidity or atmospheric pressure measurements.<\/p>\n<h3>4. monitoring systems<\/h3>\n<p>In monitoring projects, for example, in the context of environmental or health monitoring, the Arduino RTC allows you to mark the exact time of recorded data.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div
